tavis: this is the cofounderf twitter wch has become a cultul and social phenome around theorld, as if you didn't know. and bizas named to the list of the 100 most flualeople in the wor. last ek when twitter crashed, following a hacker' attack, it became one of th biggest stories the planet in a matter of hours. biz stones here. glad thave you here. how you doing? >> excellent. >> you survid the crash. >> we did. >>hat have you learn on this si of the crash? >> this is wt is called denial of svice attack. it i pretty common on the the internet. it is not going away anyti oon. whate learned, you got to tune ur systems t handle thi scale of assault. we spent 200 catching with the popularity o twitter, getting there thnically so we're stabl and along comes this massive attack -- we

learned lot from it. we worked behind the scenes from folksrom google and oer companies to figur out how to op the attacks and better deal with them in e future. tavis: does that mean -- you said how toetter stop the attaks. >>etter deal wit them. you don't really stop them. tavis: that's whai go askin you can't op it. >> n it is -- beeve it or not, there's not so great pple out tre on the intert. this kindf attack is basically, i don't kw if you mow exactly wha this is -- it is milons of sort of zbie computers that have all been infected with a piece of software that is just waiting dormant from a command for somebody. they wait uil someone utilizes them. and then they say, everyone go, thisebsite,illions of illegitimate request which then block out all t legitimate reests from aone

accessing the site. th's how they den service to legitimate use. tavis: i assume to be hacked ans you have gotten to a evel where you're gnificant enough and big enoughnd the story comes big enough for the hacker to succefully try to hack you. it is a back ended complimt. mitc you're not a targetntil you bece pular. tavis: much bter said. you say it easier tn i did. what is the nickname biz come from? >> unfortunate it comes from me not saying my full ne when i was a kid. my full name is cistopher isaac stone. i couldn't say christopheri said biz bur it kind of sound the same. it stuck and i tri to go by isaac st of my lifnd do i in some places. t biz, oer people find out

ople call me biz they want to call me biz tavis: it is reportedo much the ccess you've had and some placeseen repted. the ck story was. ll me what you were doing. tell me your back story prior to twitter. > before, i was working at ogle and before th another start-up. i n't know how far back you want to go. i was at atartup that was a rival start to myurrent cofounders startup whi is calledlogger. knew of eachther through the internet. i left mine. he sent m a note a said why don't you join us. that's when we actually met. originally sort of an arrival way. and then we became colleagues a google and w looked working together so much, that we both left google and we started working on anothertartup that was a podsting sartuthat had to do with audio on the internet. we weren'ts as interested in thats as we shld have been. that led to experentation that

led to twitter. tavis: how do you conex-if yulizeomething that grows -- this phenomenally big i such a short riod ofime? >> iis an interesting questi. it has gwn faster than anythg we worked on befe. it hasrown at a phenomenal rate. it is a great chaenge. it now a very interesting and intriguing technical challenge for our enginrs too. thway you deal with it, you focus on the team. and the core. wectually think it -- when we think of ttter internally, we think ofhree things.ñ twitter the technology and the product and th company. andhe culture. and we -- we give eql atteion to those thing what we reallyant to build is a companyand what weeally want t focus on, notss necearily the triumph of technology but the triumph of hunity. what pple will do with a simple technolog that's what we wt to happen. our jobecomes keep the service

running tohe best of our abilit tavis: you sd something a moment ago. it got my attenon. it is at the heart f me of what is best about twitter. that is, used by humanity. the humanitarian purpos that twitter has en used for. there's all kd ofxamples. we could snd hours talking about the sties in the news and ttter has been successful employed. e flip side of that question, though, is did you gs ever imagine all eillyness -- i laughed at what people ant to knowr care what i cog ery minute othe day. other celebrities provide more infoation than i provide. did u ever think that wld be one of the usageof it? >> we dinitely. the very firstxperience -- i had with ttter. we creat the prototype in abt two weeks and my cofounder jack dorse and i, we cated it in two weeksust to see who would like this.

we asked our colleagues try it over the weeke. i was tryingt out. it was the fir weekend. my wife and i just bought our first house and i had t rip up the carpet fm the previous owners and it wa a hea wave in berkeley at the time. itas terrible work. i was doffering this i did not want to discover. i was curng, why did we buy this house? my phone bzed, it wa evan my other counder. said i'm snipping wine after a massage in napa valley. i thoht this is funnye's doinghat and i'm doing this. and laughed and that lahter product i want toork on. it made me lau. but in m opinion, humor is mor important than people give it credit for. it is a very important delivery mechanism for information. a lot of times hum is where truth is. humor is a way for hans to

convey things they wouldt otherwise beomfortable doing. th sillyness was actually t me a signal this was a great thing to work on. after this, we started realizing during earthakes and wilires, it was a usefu tool to disseminatenformation through a groupf people. tavishow big of the celebty embrace of it has been to th fostering of it. >> theelebrity embrace and then you can put these inrnational event that is hav occurr -- muss the celebrity -- sort of embracement ot. and i thk it helped me grow. the celebritys have large vomes of people already. you have someone like lance armstrg andartha stewart using the service. th're interested -- ther are peoplenterested in what they'rdoing. narally they attract people that want to follow tem on twitter. t flip sid is they ve a werful tool. someone like ashton kutcher has access to 3 million people like

that. he sends a message to 3 or 4 million pple. it is growing every day. for us, i think, the adoption from intertionally well known pele has been a goodrowth mechanism. but i thinkhe flipide of it, it is valuabl for the celebrites. tavis: do yo know, and what does your researc tell you about the e group -- ian ptty much guess the group that most embracewitter. i think now about -- i was talking to my mom. my mom has a cellhone. people's gndparents have cell phes. its a technology tha everybody eveually over tame came to embra. can you seeeniors embraci twter? absolutely. we don'tnow a lot of informtion demographically speaking becausehere he don't ask people too much information. anecdotally we see a wide rain of -- ran of people. i'vead people tell me my whole senior center is getting on

twitter. there'over 4 billion mile phon in use on the planet. every one is a twitter ready device. becausewitter works on texting or sms. that's most ipiring to me, there'snly 1 billion web uss. those are fwi twitter ready. u put them together,ou have a wide swath of peoe that will have access to theetwork. wh surprises me about s.m.s., its available in parts of the world. they can ask a questionn twitter. does anyone kno if i could get a better pri for for this grain? then they have access t a real-time netwo. and someone says you could charge double. and then that person's life h been changed because they cld charge double. and two we knowhe price of grain. that could be intereing infoation. itter has on top of it, search

functionality. everythis as it comes in in al-time is indexed at subsecond speed. you could srch twitter for what anyone i saying at anytime tavis: the next question. thiseeps popping up. how do thesehree brillnt guys that come up wit a ver simple but brillnt concept ever turn this int money. everybodys using it. the numbers you lai out now, how much bigger, it can be, where is the money in thi >> first off, iis not just us three guys. thers about 50 or so people working up in a hoft in s francisc working hard. it is all of us rking together team. there's tremeous potential for money and revenue. what we want to do as a company is have a positive impact on the world, and not through the technology but what pple will do throughhe technology. that's the main goal. the open exchae of information could have a positiv impact. we need to fuel thatrowth a

with money, order to dohat we need great sustaable businessnd a business model. theompany was fnded two years ago. what we have csen to do is foc on value ove profit. the way we define value is getting theystem to beorking on as manyell phones as possible in all regions of the world. at's our focus. that being said, wha we want t do is start showing signs of life in terms of generating revenue. ma people are asking the same question you'r asking. i think they're asking it because they wan to know, are you going to be around? we like the service,e want to invest in the service. thers 10,000 different apications and companies being built on top of th twier platrm. we opened up our infrastructur they want to say,rove to us th you're going to be around a while. we want to show signs of le is year. begin to do that b -- interacting with the -- with the manyommercial account tt is have already popped up o twitter. and twitter, y can't think o

it lik a social nwork. it is not about areou a friend of mine? it is abo millions rah millions of dferent sources of informati that you chooseo curatend follow. tavis: what you say about those commerci interests and showing a revenue stream this year, does tcha mn advertisement? >> no, you have cpanies lye like coomast and they're using twitter. or a cookie shop? fran. saw a sign. they said follow us on twier and we'll tel you whe the cooks come out wm. so evebody buys their cookies eople are using twitter to raise the bottomine. we think that bause we're tting value out ofwitter, we want to follow that vue. how c we offer more value. twitter willemain free for everyoneut we playffer a

ditional layer of value, for the commercial accounts. whether it is through certificatio how can we make sure everyone knows this is definitely jetblue and not somebody pretending to be jetblue? a vaety of features that would have a paid lel to them. that's how we begi to have relaonships with these commercial entits. and that's justhase one. then we build fromhere. we go from tre as we ha been ing from the product ielf. tavis: youl figure out how to make money at some pnt down the road. i' betting on biz. christher isaac stone,e can say at this many years later. nice to have you here. forme e.r. star up next. tavis: welcome gloria rben.

she's starring onraisinghe bar. it as sunday nights on n.t. he a scene. >> you pursued legal charges the reason is togive you a chance to keep it qet. >> youhould have come to me. we work tngs out, boss to boss. i thought you kne that. >look if i thoht for a minute that the d.a.'s office had the power to compensation mr. lewis for wrongfu arrest, false imprisonment and malicious prosetion. >> you underestimate me. did you er think i had a opportunity to -- >> you're going to retaliate. >> it is a misdemeanor 90 days, not just 15. it is constituonal. >> that' a threat, it is not a lution. ho about you address mreal concerns here. tavi if i ever nee a public defender, i want glori reuben.

>> isn't thatun. that's fun, but interesting, cause i don't want bash, public defenders d a gre job. but unfortunaly because of e culture w live in. every so often you read a heins story about a plic defender that le their client down. at's not the role y play. >> indeed. i know it isefinitely a thing that people unfortunaly have to deal wh because theork forcof public denders as d.a.'s but the workorce of if you believe defenders, they' so overloaded with an extraordinary amountf case, paicularly at this time wit cities and stateare tough on crime. that means everybody and anybody get arrested. also, there have been other television pgrams that deal with the judicial sysmhat -- have not nessarily portrayed the role or life of a plic defender in a mt kind o positive w or a way that sho them being intelligent and capabl tas: what makes this show different? >> that we do that. we show public defende are not

just oveorked. of course, there are manyf themhat are extreme loyal to thir tchinets, that are inlligent and work diligently to hefully provide the best kind of legal counsel for their clients. oftenmes, pe they butt up against system that i't necessarily kind of cducive to being understanding about individual situation as much ast is about lking people u tavis your character? >> raz. i like her. tavis: i don believe everything i rd. but i ink this is true. you said you think you were perfectly cast in this role. not often a actress says that. what did you mean? >> i think iis a good f. i like the way she's a leade you know, have found tt notentim i have foundhat roaiceatlen e cth me, ve -- very uch parallel for some reaso the things in my life. i ke that she's a leader and obviously being the voice for those who do not have the voice for themselves.

and reprenting people -- that literally can't affordo represent themselve d i find that -- i've been ry blessed of courseo have been having a lengthy career so far and hopefully that wl continue to be able to usey success, in order to help be t voice for people in different aspects and differe act victim i'm involved with. in that way,t is a great parallel thing. think clearly she's intelligent an she looks good an she's --hose things i like. tavis: to yr point earer, you id oftenmes, i'm parhrasing, oftentimes you find roles andharacters that e oofered to you thatarallel yourife. is that to your thinking, your mind,s that glori divine interventio is that by design? how does that happen, do you think? >> i think the first thing you sa is very much in play. the divine intervention. if i look back and look at the pastnd how itnfolded with with myareer, and where ited

not justcting but how it led me tdo other things, in no way could i have en imagined - that tngs would have turned out the way they have. and so -- 100%, it is divine intervenon. absolutely. tavi i was in a conversation on my public rio show just the ear day as i often am about hiv/aids. for a variety of reasons, but mostly becausee don't have a cure and thinking aut you comi on the show. i'm connecting these things, because my forgoen and we did a show her -- celebrang the close of the wp up o e.r. i'm connectedo wrap-up of e.r. d you coming on the program and been on e.r., connect these dots. stay with me. you had been on e.r. i had fgotten, it was some yrs ago, that way before, we were reay talking about thi as we are now,ou playe an hiv-positive character, on e.r.a. >> that's right. tavis: wt do you --

>> i think verymuch again it is diff divine intervention in number of ways. and en she found out she was iv-positive. this was 13 years ago, she was a leer sexual, married roffingsal african-erican woman d got hiv. we were ahead of our time. e.r., the first few years was ahead of itsime in a number of fferent ways. but for the issue of hiv tha storylin was complety ahead of its time. it is now -- it is 10, 13 years later at we find that professional heterexual, afican-american women are bng infected at astouing rates and that indee because of reruns people -- maybet is in their mind a little more that i play this character on television but as a socie, we have dropped the balon the iue. hence my, about five yrs ago, feeling a strongeed and desire to pick up that ball and -try be out there in the world spifically in the united states, inhe african-american and latino communities,etting e message back out there,

cause we forgotten about i it is like i doesn't exist anymore. meanwhi, the man dem i think ntinues to -- to spread here mounta united states and i'm very thankful for - for the numerous reasons that barack obama is our psident. ght. and when it mes to this issue ofiv, you know, finallye have a lder who not only acknowledges that this ia pandemic here in the united states, but is creating and will ilement a national straty and has also put together 45 miion dollar media cpaign that wl start now and will target the demographics andhe communities that he, affected e most by hiv/aids. so, you know, it is aittle -- uptting sometimes tha -- that we haveind of gon backwards in a way when it ces totigma or lac of conversation abo it or homhobia or incarceration or pfert or these other element that islay int the pandemic and the bla and

lino communities in th united ates. it is upseing we haven't moved forwar buts as is often the word we have used a a lot lately and in the last year, there's hope. clearly it starts from leadership. tavis: iis the perfect emple of how hollywood can lead the discussion. the power it has to us it appropriately, to get o ahead of the story to make people wrestle with it. we talk about hiv/aids. i wated you over the years work not just on the scree but in the commuty and in a variety of ways. andhat is tt -- at the center of, clely your love of humanity gen all of the caus beyond h/aids that you aach your ne to. the name card i have aached myname card to and wking diligently i is the issue of imate change. i am currently honored to be vice chair of e board of trustees for wat keeper alliance.
