announcer: from our studios in new york city, this is "charlie rose." charlie: we begin this evening with our continuing coverage of election 2016. republican presidential candidate ted cruz scored a strong victory in yesterday's wisconsin primary. the outcome dealt a significant blow to front runner's donald trump's passing the nomination. it could also pave the way to a contested republican convention. mr. cruz: three weeks ago, the republicans said wisconsin was a perfect state for donald trump. >> boo! mr. cruz: but the hard-working men and women of wisconsin stood and campaigned tirelessly to make sure that tonight was a

victory for every american. [applause] charlie: on the democratic side, bernie sanders beat hillary clinton by 14 points. mr. sanders: do not tell secretary clinton. she is getting a little nervous. and i don't want her to get more nervous. but i believe we've got an excellent chance to win new york and a lot of delegates in that state. charlie: joining me now from washington's jeanne cummings. she is the political editor for "the wall street journal." here in new york, the hosts of bloomberg's "with all due respect" and the managing editors of "bloomberg politics," mark halperin and john heilemann. and if you have not seen "the circus," you should go see that, too. also here, mike barnicle. he is a political commentator and contributor to msnbc. i am pleased to have all of them here back on this program. mark halperin, i begin with you. what did wisconsin change? mark: every three episodes i'm on here, i like to quote one of my father's jokes, and today i will quote this one. "only two people understand how the international economic system works, and,

unfortunately, they disagree." there is so much ambiguity now amongst very smart political observers in the game, journalists, people watching from afar who know a lot about what everything means right now. what wisconsin did on the republican side was put donald trump on the defensive and made it mathematically more difficult for him to get a majority, although not impossible, and it made ted cruz the primary opponent. john kasich is more marginalized now than he was before. and it gives cruz a chance to continue to have momentum coming into the northeast. on the democratic side, it may give bernie sanders a chance to extend his fight, extended his streak of victories. and it made it possible for him, if he wins new york, to continue along, and to continue win and make it harder for hillary clinton to claim that race is over. charlie: has bernie sanders winning in new york become more possible? mark: i think it does. it gives him momentum, and it puts her more on the defensive, and that showed his ability to win in a state with some diversity, and it showed her inability to put him away.

there is really no reason why a frontrunner shouldn't be winning wisconsin against someone who mathematically has a very tough time getting majority. it still is a challenge for him to do well in new york, but the clintons have been worried about new york for longer than they have been worried about wisconsin. they know that sanders' message will play very well here, and she has to worry now that, if he does win new york, that he will go all the way to california, with a real credibility and a real argument to say, "i'm still in this." charlie: and good momentum. and voting groups that support him come into play as well. mark: still a big delegate challenge for him, because she has a lead and the democratic rules make it hard to catch up to someone with a lead, but he will be able to go to california. and i've started to think, as long as the republicans are going to have a contested convention, it makes it easier for sanders to say, "hey, our convention should be contested, too. let the delegates have their voice in philadelphia as the republican delegates will have their voice in cleveland."

charlie: you want to add to that, sir? john: well, that was very comprehensive. charlie: yes, that was. john: i'm not sure how much i have. charlie: that's why i said "add." and mention your father. that's not bad. john: well, there's no question that -- the other thing on the republican side is that what happened in wisconsin has emboldened the "never trump" forces. they've been looking for a blueprint to try to stop trump for a while. charlie: but is there a blueprint now? john: there is a little bit more of a clue. first of all, it gives them a sense he can be beaten. and there are states on march 15 where people spend tens of millions of dollars, in florida, and trump still waltzed to victory in those states. in this state, a combination of a determined effort on the part of the republican establishment in wisconsin, in the form of scott walker, in the form of much of the elected establishment there, the talk radio hosts on the conservative side, and strategic voting. voters who, in many cases, did not particularly want to vote for ted cruz, were not particularly pro-ted cruz, but who looked at the landscape and said, "what we really want is donald trump not to get to 1237 delegates, and we have to stop

him. and so, we are going to hold our nose and we are going to vote for the person who has the best chance to win here, in hopes of playing the long game and getting to cleveland and then having a whole new election on the convention floor." jeanne cummings, what are the lessons from last night? jeanne: well, i think wisconsin is a very unique example.

it was a pretty perfect storm. ted cruz's victory there is very important because the math now a donald trump can't get the 1237 delegates he needs unless he's going to have to rely on delegates that are not that is of course where he has been week. cruz is in colorado picking up some of those unbound delegates. charlie: when you watch what is happening this year the the toory he's been on

bit like what mark's father said. mike: it is endlessly fascinating. we have to look at it from the other side as well. the delegate selection. the objects of their attention. the volatility in this country among the electorate and the feelings about the country, where the country is headed -- it is a sense of, you get, clearly, a sense of anger and a sense of optimism, the spending -- depending on who you are speaking with. you go to the sanders crowds. there is a vibrant, young sense of optimism that bernie can change this. you go to the truck rallies and the cruz rallies and you get a the trump rallies and the cruz rallies and you get a sense of frustration, someone is taking our country from us.

donald trump is strong enough to get the country back for us. it has been a ten-month lesson in changing culture in this country. charlie: everybody thought that donald trump would change presidential. i did not see that last night. and the whole idea was that now he needed to show that he was more presidential. and the circumstances of wisconsin are less likely to produce that because it goes back to his core. this is a contest. it's about winning. and i will do all these other things after i win. >> you can look at the last three weeks and focus on where he has not been more presidential and created more problems for himself on twitter and through some interviews, but you also look at his speech to ai pac, which got overshadowed, because brussels happened the next morning. he gave a pretty well-written speech, first time in his life reading from a teleprompter. you can see the hires he has made, the old hands, the

establishment of a foreign-policy team, which some people found underwhelming, but at least he took that step. he constantly refers to the fact that his wife and daughter say to him, "you need to be more presidential." it's a one-person operation, with all due respect -- this is the way he has operated. donald trump is, in one way, the most surprising person any of us have ever covered, and, in other ways, he is the most predictable. you see the things he says and does, and they are a product of his way of operating in the world. and that has not been, for most of his life, presidential. that's just not his thing. >> he has tried it or mainly to take the advice of his family intermittently to take the advice of his family and behave in a more presidential fashion.

his incapacity to control himself, in terms of wanting to be the center of attention at promiscuously doing interview after interview, television show, tweeting all the time, retreating other people's tweets regardless of who they are from. it comes in the middle of a week in which the combination of sending out that tweet, which overshadows all of that other stuff, it gets amplified by his opponents. he has a campaign manager who gets arrested for battery, accusation that involves a young female reporter. in a moment where he is totally unprepared in the conversation with chris matthews for a basic question about what he claims to be his possession on the question of life and abortion, he totally screws it up in a way that causes potentially irreparable harm within a hugely important part of the electorate going forward and also,

obviously, in wisconsin. his lack of preparation keep bursting through -- but his core charlie: it's a bit like the old story from vietnam, the scorpion and the turtle. i stung you because it's my nature. jeanne: john raises a really good point about the amount of damage that he did to himself. if you look at the exit polls, trump has generally gotten about 36%, 35% of the women. when you look at exit polls in the prior primaries. you look in wisconsin, he got about that number. however, cruz beat him by more

than 10 points with women. the women who had been with trump, like many of his supporters, stayed put. there are very loyal to him. they are willing to tolerate a lot of mistakes. however, those are not with him right now. they moved. if that keeps up, that's going to create more opportunities for kasich and cruz to keep chipping away at the margin of victory that he needs, that trump would need to try to seal the deal. charlie: late deciders are not voting for trump, correct? >> given the fact that he is uniquely a solo act in american politics, a solo act. he is flying alone, listening to only what he hears in his head. he has no message discipline. given the fact that running for president is largely about message discipline -- doesn't this spell his doom? so far, anybody who has

predicted his doom has proven wrong, up until, literally, this week. this is the first time he has paid a price electorally for some of the errors he has made. he has made errors with impunity throughout the race so far. charlie: is it reaching a critical mass? we all know he is coming to new york, his home state. he is expected to win a huge number of delegates here. he caused himself some damage in the sense that we already discussed. he has made a contested convention way more likely because the way he lost in wisconsin, and he has done long-term damage for any potential you might have to become the president of the united states, because he has alienated, in a profound way, women and hispanic voters. there is no world in which you can be the president of the united states if you have a disapproval rate of 70% from the hispanic vote and the female vote in america.

>> trump is the nominee before the convention. trump wins the ballot at the convention. cruz wins the nomination at the convention, or someone else does. paul ryan, john kasich, whoever. charlie: an increasing number of people believe it will be paul ryan. do you believe that? >> i believe that's the most likely non-trump/cruz outcome. i said this morning and got some heat for it that trump is still the most likely nominee by a lot. of the four outcomes, two of them involve trump becoming the nominee. that's becoming, after last night, until we see that he can right the ship, it's becoming less likely that he will be the nominee, but he is still the most likely. >> do any of you three experts think that donald trump gets to a second ballot in cleveland? >> and wins? >> does he get to a second

ballot? if he can't get there in one, does he get to a second ballot? charlie: what do you think? >> i think no. jeanne: there are some states that are -- state delegates that are bound twice, but they would not amount to enough to make a significant difference on that second ballot. charlie: i want to go to the democratic race in a moment. let's suppose you are ted cruz. what do you do? you've got more organization. you've got more discipline. you shown you are willing to fight back at trump, on the heidi business especially. what's his strategy? >> accumulate as much as -- as many delegates as possible informally. i believe that they believe scores of delegates will be forced to vote for trump on the first ballot who would not vote for him on a subsequent ballot.

charlie: how has it changed? >> every state is different. they are bound because they are elected -- the press often over-excesses on over-obsesses on electability. i believe that when we get to the convention, if trump has not won it -- charlie: how far back do you want to go? mark: to reagan. charlie: john f. kennedy said himself that if rockefeller had been the nominee, he would have beaten richard nixon. >> by doing well in head-to-head polls, acting like someone who could win --

>> regardless of what you think about the republican party's propensity to elect the most electable, the people in the room will be focused in a laserlike way on the question of electability. the broader electorate, maybe, maybe not. in that room in cleveland, that's the only thing they are going to be focused on. charlie: bernie sanders. mike: it's amazing how much of the energy and movement behind bernie sanders that the clinton campaign missed for so long. from utica to rochester to syracuse, doing extremely well. charlie: how much of it is anti-hillary clinton and how much of it is pro-bernie? how much of it is a genuine understanding on his part and the voters are of what his camp -- voters' part of what his campaign is about? mike: i think it is pro-bernie,

because the audience he has attracted, the people who support for him -- support him, vote for him, donate money in the millions, recognize in him someone who has been espousing the same message consistently for 30, 35 years. and he is sort of unique on a public platform today, given the way politicians change their minds and their views on a weekly basis. charlie: a lot of people have been wrong about bernie sanders, haven't they? >> to some extent, he was underestimated, certainly from the beginning. but when reporters went out and saw his rallies and talked to his voters and learned the passion that they had, i agree with mike that it is more properly and less anti-hillary, but not -- more pro-bernie and less anti-hillary.

ted cruz says, "i agree with bernie sanders. the 1% has gotten too rich under barack obama." when ted cruz starts talking like bernie sanders, you know the guy struck a chord. jeanne: one of the things that has really struck me about this campaign is that the motivating -- the animating factor, for both bernie sanders' supporters and the donald trump supporters, are very similar. both of them are attracting working-class people who feel frustrated with the system and they are not doing as well economically. so, the motivations on both the far left and the far right are very, very similar.

this goes to what michael said earlier. their solutions are very different. bernie's supporters are turning to want government to help them solve these continuing problems and frustrations that they have had, whereas trump's supporters want him to blow the system up, the system that they think has been keeping them down. so, it's a solution to very similar frustrations and problems that we see animating so much of the edges of the campaigns. the republican party, the donald trump is nominated, they have big problems. their nominee with those problems or they nominate someone else and he convinces his supporters that they have been cheated, and i'm going to stay as a factor in this one way or another. it's a dilemma you don't want to

have in a political party. donald trump has started laying down the predicate for the complaint that he has had the nomination rightfully stripped from him. he is already making that argument. the people who follow him will believe that argument. those people will not vote for the republican nominee if it is not donald trump, if they believe the establishment has stripped away what was rightfully his. basically, if you put them under sodium pentathol, they would say, we know we are going to lose the general election, we understand that. we are trying to keep our party from being split in two. we need to try to hold the senate, hold the house, not have this be a cataclysm. charlie: that's the reason they come to a different view of the man they hated so much.

he will lose to hillary clinton, but it will not be a cataclysm on every ballot in the country. charlie: the democratic party, the dlc, the idea of a guy who, because he had been in arkansas politics, understood that you had to be very centrist to win -- >> i don't think it's dead, but it certainly is on life support. the reason is not the similar from what's gone on in the republican party as well. i think you have millions of people sitting out there, and we have been speaking around us and to this this evening, but politicians in power today in the house and senate, especially in the senate, seem to have no idea and they cannot articulate the pain, the hurt, the damage that was caused in 2008, 2009, to so many people who lost jobs, homes, 401k's, any sense of hope for an immediate future for

their children. >> and i think bernie sanders also speaks to the iraq war and the pain that has caused america. charlie: does that resonate? >> it does, for so many families, left and right. trump says the same thing. trump says wall street has rich people off, the iraq war was a mistake. >> one of the principal reasons that the iraq war resonates, if you stand in those crowds, charlie -- the people who were damaged in 2008 and 2009, it is their children, largely, who go to places like iraq. >> people in new york and washington talk about those things as an important public policy. these are deeply emotional, resident, personal things, losing a family member, having a family member wounded, not being able to retire -- these are big, relatively recent historical events that sanders and trump talked to with emotions -- talk to with emotions.

>> i've been a lot -- to a lot of sanders events and talked with senator sanders. he is very clear, when he first got into the race, he wanted to prove, more than anything else, that his positions, the arguments he wanted to make were not fringe positions to his great fear was that he would lose very badly and that he would, in fact, do the opposite, that he would be relegated, that the arguments he was making would be consigned to the dustbin of fringehood. that's the exact opposite of what has happened. the democratic party of bill clinton is dead. the party of bernie sanders, the arguments he is making our way or the democratic party is now. he has dragged hillary clinton to the left on almost everything. the heart and soul and mind of the party is now a much more progressive/liberal party than it was 25 years ago. you could not be a competitive candidate in the democratic primary right now if you were bill clinton with those positions, the clinton -- that

he advocated in 1992 would find no purpose in the democratic party now. that's why bernie sanders has been so powerful, he is where the head and the heart of the party is. charlie: thank you so much. pleasure to have you here. back in a moment. stay with us. ♪

♪ charlie: chris cox is here, the two products officer at facebook. they command 1.6 billion users around the world. he has driven some of the most successful initiatives, like the like button and the news feed. yesterday, they unveiled pushing and to live video. it will have a host of new pictures that will allow users to communicate with friends across mobile devices. i am pleased to have chris. welcome. guest: thank you for having me. charlie: so, you are at stanford. you completed the undergrad and you are getting an engineering degree. zuckerberg arrives. guest: it is 2005, mark and dustin and chris had moved out to palo alto and they were recruiting folks who had dropped out of stanford to help them scale facebook. at that point, it was 5 million american college students.

and there were about 30 employees or so and i wanted to meet mark, i had written about him in the stanford daily, that was about the most prestigious paper you can read about him at that time. the world was not taking this stuff seriously and working at startups was not considered a good idea. charlie: and mark was not think about 1.5 billion users at that time. guest: no. i went to the office, mark was not there, justin timberlake was not there either. but i met the head of engineering and a guy named adam d'angelo, early employees. i really liked them. they were smart and humble and a dedicated. and they had an idea that facebook was the seed of collaborated directories, something that had never existed before. they thought of it as a wonderful thing and i was

attracted to the personalities in the company, the vision they had and i consulted my parents and people that i was friends with and luckily i ended up making the right decision to join. charlie: what is facebook today? guest: it is super focused on how people communicate and connect with each other using technology, that is our core mission. all the way up to facebook and instagram, which is about trying with large groups of people.

oculus we think of as virtual reality, we think about that is enabling a new type of communication where you are sharing experiences with people in an immersive setting. charlie: people talk about you as having brought to facebook a strong sense of emotional intelligence as well as iq, in a sense that being able to communicate with people who want to come to facebook and at facebook, about what facebook means, the culture, and why -- and the mission. guest: i started about nine years ago doing an orientation talk where it is like your first day at facebook and i command and i come and talk to you. charlie: what do you tell them? guest: i talk about the idea, the history of the company, that we are still working on this idea of building a collaboratively working directory and the way that people can communicate with each other.

that is a simple thing. but i also talk about the idea of building a medium that comes with it. and how it is a huge response ability to pay attention to details, bill something that is high-quality, and to do a good job of helping people understand. charlie: and what will be facebook live? which you watched today. on cbs this morning. guest: yes, it was an honor to a live show talking about the live version of this. so it is interesting, a lot of the ways that we learn what to pay attention to is by watching things and observing what people are excited about. and we began with a live in 2015, we brought it to public figures when they're asking about an easier way to do q and a, something that the liberties celebrities, and athletes and journalists use. we saw early traction among

people from niche scientists, astronauts, athletes come all the way up to political candidates and the white house. charlie: you said at sporting events, we know that twitter will be streaming the nfl games on thursdays but you had said that what you visualize is taking it in the locker room. almost getting access to live access to places you are not normally. guest: yes, i think that people want to be behind the scenes and there is something about the experience about going with somebody to a place where you are not normally on the screen, that is really exciting -- both for the athletes, villanova just did a live thing from the locker room. i saw it live last night, and the soccer team in the u k, doing goalie warm-ups.

which is not something that he would ever see on tv, but it is great to watch because you have a picture of what the life of these athletes that you see on the screen so often, is actually like. charlie: what do you think it will change? guest: it is early to tell. one of the things we are hearing is up and down the spectrum, from musicians is a great example, just giving a server connected to them with their fans. or even filmmakers, steven spielberg was live last night. charlie: how was he live last night? guest: he was talking about his upcoming film based on the route dahl book. he was sitting there in a room, answering questions about what it was like making the "bfg," and it describing his experience.

charlie: and it was users asking questions? guest: people who followed him and came to see it. he opened the application, had the video on the phone and he was recording and sending that image. charlie: it was a smart phone? guest: yes, it is available on iphone, available in about 60 countries right now. the coolest thing is steven spielberg is somebody that i never have really gotten to see in an unproduced environment. charlie: that is great. it was cool to be able to get the chance to see him. and he also felt that excitement. you can tell, i do not know exactly what he felt, but it seemed like he was having a very candid, good experience. charlie: how is this different from periscope?

guest: the most important thing is scale. you have many people getting millions of views, you have people who have a huge following with them and their ability to reach those people in one place tap is very powerful. charlie: how did they announce it? guest: they go to their application and hit a button that says live. and their followers get a notification and people can subscribe to say that they want a notification when this person goes live. charlie: so if you wanted to participate in this interview and watch it and you can tap in life with steven spielberg, you do it. guest: so what he is looking at is a picture of the video and comments coming in, and he also sees reactions coming by, because people are hitting "like," and "love," and if he is explaining something sad, he will see a sad face.

but then he can do something that is really neat, have a raw and authentic reaction to people who are there. this is like people and their friends doing this. i have a son and i infrequently i am frequently having experiences where he is doing things for the first time, and i want to show my family, my extended family who is around all over, i want to tell them, hey check this out. suddenly that can be a powerful experience for both of us. one feature we launched allows you to go live in just a group on facebook, which for me -- charlie: so the only people who could access would be those people. guest: exactly.

so basically i am sharing a lot of photos with my son, about 100 photos a week, and they all get a notification to check it out. charlie: and they can talk about it, ask about it. guest: it is really cool. charlie: my sense is, we know that facebook has benefited from mobile. we have seen all aspects of the surge come away know what cloud is doing, but video seems to get more emphasis now. because of what it is doing with streaming, how it is affecting the cable business. more than anything, video has merged into the internet. guest: it is really interesting. if you look at the traffic that goes over the internet every day, about half of that is video. i think what is interesting is

now, if you look at all the things you do on your phone, messaging and the reading the news, entertainment, even gaming and shopping my travel, sports, more and more of that is using the media of film in terms of how you experience it. with messaging, maybe you are doing more voice calls. social networking, maybe you're looking a video and looking at instagram. more and more people are creating their first video. the first time for hundreds of thousands of people that they created a video on first -- on facebook. it never occurred to people that they could do that. so we are just beginning to see the transformation of our mobile devices into things that have moving pictures and where we are comfortable. charlie: it goes beyond data. guest: it does.

if you just look at live alone, the amount of every structure problems that need to be solved in order to simultaneously stream the same frame at the same moment in time to hundreds of thousands of people all around the world. charlie: you did not just wake up and start doing this. guest: we are so lucky we have this engineering team. we are able to build something for people to make it easy for them to do, whether they are on moto e in new delhi at night, or on a new iphone in new york. a part of what is so hard is building these experiences that can be used in different places all over the world. ♪

♪ charlie: i was with mark -- what is the number? guest: it is just over 1.5 billion. you expect to have 2 billion users? guest: the thing we are focused on right now, the people coming onto facebook today, what experience are they having? if you look, about a third of people coming onto the internet are going to be new. if you look at what is a new person -- charlie: is it india? just because -- guest: the size of the country

and the growth. data plans are getting more affordable. charlie: so more phones in india compared to china? guest: i would have to check on that, but i know that there is a lot of mobile phone adoption. when i was in delhi in january, they were announcing the billionth phone that had been gotten. there is a lot of entrepreneurial energy around the adoption of phones in india, but when we look at somebody using facebook there, they are on a phone that maybe you and i have not used for a few years. they are on a 3g network and it is slow. so building stuff that works well there, making instagram work well there, requires a huge infrastructure. guest: sending researchers to spend a lot of time there.

we need to sit down with people and ask them to walk us through the experience and ask why something does not work for them. charlie: what is your mission today? guest: to make the world more connected. what it means for us is as more funds get adopted, making better tools for your experience. if you look, there is an interesting example where, we were looking at how people were using live so far and there is a guy -- charlie: how are they? guest: there is a guy who is a migrant, his name is bekhari, and he runs a group of about 1000 syrian migrants and it is a place for people who have recently come to germany to have a place. charlie: so that he can talk to them and work on assimilation.

guest: yes, basic things. charlie: has anybody seen my -- guest: all sorts of questions. and he started doing the live q and a's. one thing he started, helping them apply to german universities. these are things that we could have never imagined to be possible with the tools, but it is a reminder of how important it is that we build these in an open way. charlie: when people talk about the voice of the user, what do they mean? guest: when we talk about building things, a lot of what we are trying to do is remind ourselves that no matter what we are doing, we need to pay attention to the person who is using the product. even when we are talking about how we build something, pay attention to the language that we use. that is probably what they mean.

charlie: when they say that you are the chief product officer, the first thing i imagine is that you are the guy that is in charge of developing the products for facebook. you are the connecting link between creating products and making sure that they are maximized in terms of use, and in terms of their connection. guest: yes. but what is so interesting is that what state -- what used to be building products for people who look like us, sitting in a shared office, this is a skill that is immense, one billion people a day. it is people in thailand, indonesia, people speaking a lot of different languages and it requires scaling. and our ability to understand. charlie: when you sit with those smart people at facebook. and you think about -- they would love to know -- guest: i am thinking myself.

charlie: am i going to ask that question? the 10 smartest people you know and you think about the possibilities, help us understand the idea of what might be possible, because so many people are connected. what does that do in terms of possibilities, and both good and bad? guest: i mean, the thing -- charlie: social media has been abused, as we know. guest: did we spend a lot of time figuring out where there are bad actors. it is pretty amazing how rare and far between the stories are, given how intensely facebook is used every day and i think that is a testament to the work that we did to make it safe. when i look further out, some

scenarios we are excited about is taking more immersive experiences, rather than sharing just text or a little photo, or a high-resolution photo, sometimes you want to send the whole 3-d, 360 experience, as if somebody could be there with you. charlie: so a kind of virtual reality? guest: it will start with 360 film, a medium that is just starting to get traction. charlie: and video. guest: imagine having video stitched around and it is 3-d and then having that about 16 frames per second, four k per i. so a lot of information. when you think about something like when your son is taking his first steps. you want to capture it, so you can show it to the grandparents. but it would be really cool to be able to invite people to come see it and be there with you, closest friends and family.

and if they can use a phone to explore that experience, put on a virtual reality headset to experience it, that would be an interesting scenario and a powerful scenario. charlie: is it true that more and more institutions, public and private, corporations or government, are using facebook to make their announcements? guest: we are definitely seeing people across the board. charlie: four an announcement from an athlete. guest: absolutely. and you have seen political candidates, you have seen them on your show, and i think it is because of their is a direct -- there is a direct connection. people love that feeling of being immediately connected and to have it in a way that feels casual and less produced my that is something that more institutions are doing. hughes who was therefore obama

in 2008 and then got into journalism. what is the possibility in terms of around the world, of using --facebook politically? the idea of twitter as a factor for people who are trying to create revolution, it becomes an important tool. guest: i think one of the most interesting things in my experience, that started to happen, is more discussion. it is one thing to have a politician say something, but it is another thing, where i think that facebook really goes, is to have it diffused and have people discussing topics as they arise with the people close to them, distant from them, and have debates arise.

there was a recent article in the new york times that was basically on young men being emotional. it was really good. charlie: i am not young. i read it. guest: first of all, the piece was really good. second of all, the discussion i saw happening among people i know was just as powerful. people were reflecting on their own upbringings, what they want to see with their children and when i look at facebook -- charlie: so it was the community talking about this? guest: it was going to the newsfeed. charlie: coming about how you created newsfeed? guest: it is a personalized feed of stories that is created instantaneously for each person on facebook. and it is interesting, for the average person there are thousands of candidates' stories they can see, and maybe they will only scroll through 100.

we want those people to get the most interesting stories each day. we have done some ranking to help them get the best stories. that endeavor has become one that is more about understanding what is meaningful to people. if we just look at what is clicked on, you'll get something that were maybe people who have clicked on something say, i really didn't want to read that. or they will be inspired by something, but when i click on it. charlie: so are you -- so did you invent the like button? guest: i cannot take credit for it. i worked with a lot of people on it. clicking on the like button is like coca-cola, a secret recipe. guest: it is a feature that if you press and hold the like button, you can leave a wow, or a love. we wanted to give people a

lightweight way of expressing a emotion. we study the most common expressions that were universal. charlie: wow, love. guest: exactly. it actually changes the experience of using facebook, because now you are not is looking at the story, you are looking at the audience's response to that story. charlie: people have talked about google and search and they have suggested that at some point, you know where i am going, that a challenge to search will take it from people being able to use their friends on facebook as a means to search. has that idea gotten off the ground? guest: there are a couple of things that people are excited about using that for.

charlie: thinking, my friend i can trust them more. and they understand me better than anyone. guest: so finding people on facebook is already fantastic, you can find relatives, friends, and just looking for people and that is common. we also started to roll out the ability to find what people are saying about a topic, maybe breaking news or what is at interest right now. and now we are starting to roll out post search. charlie: what is the method for watching the growth of this? guest: we would like to see it out. part of the reason that we put so much energy on this is that in early days, we saw that this was not just public figures among celebrities, people who are already in the public eye, it was people trying things out for the first time. or dj jazzy jeff, people that i certainly was not paying attention to, suddenly were

given a window into their lives. so every opportunity we have to create that connection is a huge, a pretty special thing for us. charlie: can you mentioned -- you mentioned how ripe it was -- the market was in india. and mark was with me in china and we could see the great wall. do you hope and expect to be able to somehow figure out a way to have access to china and one billion plus people? guest: we would love to be. it is obviously a complicated conversation, i do not have a law on that one. unfortunately, no. charlie: do you have time for your reggae band? guest: i wish. turns out i discovered some of the most amazing reggae musicians in pol out though.

a group called rafa, amazing musicians. since having our son i do not get to play with them anymore, but every once in a while. charlie: thank you for coming. guest: thank you so much for having me. ♪
