upload, but five years and 436 million hits later, charlie bit my finger has made his family rich. tonight what it takes to win the online lottery. this is "nightline" march 29, 2012. good evening, i'm bill weir. there's a better than 50% chance that you have at least one apple product in your home. over half of americans do these days. there's a good chance you've heard disturbing stories about how they were made. last month we took you to china for the first ever glimpse inside the apple lines at foxconn. we were there as the fair labor association began to assess how bad things really are for the $2 an hour workers who build the

products. >> reporter: the journey began six weeks ago when we arrived at the foxconn gates, filled with fascination and dread. >> turn your mike off, please. >> reporter: it was an intriguing chance to witness the creation of the mac book, the iphone, and the ipad. ♪ >> reporter: the products that have fans sleeping on side walks in anticipation. rushing stores to buy another model of a gadget they probably already own, a devotion that turned steve jobs garage start-up into a company more valuable than exxon. but while apple is among the most beloved brands in the world, we came in expecting to find the kind of horror stories that have demonized foxconn. with over a million employees, apple's supplier also works for del and many others. while they build 40% of the

world's electronics, relatively few americans knew their name until 2010, when nine foxconn workers jumped to their deaths in a span of three months. suicide nets are still a reminder of that horror. >> an explosion today at foxconn. >> reporter: also fresh the memory of two explosions last year which killed four and injured 77. >> did it take something that severe to make you re-think how you treated your workers? >> i think absolutely. >> reporter: apple's been doing auditing since 2006, and it has led to an nigh era of openness. they revealed the names of most of their suppliers and joined the fair labor association. we were there when the head of that watchdog group began an unprecedented investigation. >> how do you know they're not putting on a show for you if they know you're coming? >> i expect them to put on a show. that's normal. but over the next couple of

days -- >> what goes through your mind when you do the same thing all day? i met plenty of workers willing to complain about long hours, low pay, bad food. we knew there was only so much an american with a camera could uncover here. so we awaited the results of the audit, including the survey of over 35,000 workers on ipads. good to see you again. and just a few hours ago, the fla posted their findings. as americans understand the term, would you define foxconn as a sweatshop? >> no. it's a very modern facility. >> reporter: did you find any evidence of child labor? >> we did not. >> reporter: none? >> no child labor. >> reporter: so what are the most egregious violations there? >> over time. >> reporter: with an insatiable

demand for new gadgets over here and a massive hunger for steady work over there, forced overtime is one of the biggest problems in china. the law here says no one can work here more than 49 hours per week. but no one obeys that law. apple's limit is 60 hours a week. so six days a week, a foxconn worker will spend ten hours a day filing apple logos on the back of ipad cases 3,000 times a shift. >> what are you thinking about while you're working? >> a lot of times, i think about how tired i am. >> they get meal breaks where they march single file for meat and rice. if they eat fast enough, they can some winks back on the line. >> reporter: how does that happen for forced overtime? you think your shift is ending, and your boss tells you you have

to stay the night here. >> the question, are people doing it voluntarily? if they refuse, will they face recrimination. >> reporter: everybody we talked to said they wished they made more money. but what about there, is it fair what they're making? >> they're paid 20% above the legal minimum wage. we asked them if they thought it was fair and the majority thought it was fair, but they also felt it wasn't enough to meet their basic needs. >> reporter: and foxconn has agreed to sweeping changes. by july of next year, they promise that workers will only have to put in 49 hours a week, while taking home the same amount of money they do working 60 hours now. but in order to keep up with demand, foxconn will have to build new lines, dorms, and cafeterias, and hire tens of thousands of new workers upon will apple east that cost? will it go to the customer?

>> social responsibility has a cost. foxconn will absorb some. the buyers, all of the other electronics companies as well, have to absorb some of this. we need to be ready to put our money where our mouths are. >> reporter: steve jobs never visited the chinese factories, but his replacement was at one yesterday. in a statement tonight, they said, we appreciate the work the fla has done to assess conditions at foxconn, and we fully support their recommendations. our team has been working for years to educate workers, improve conditions and make apple's supply chain a model for the industry. the company boasts over a million assembly line workers. other watchdog groups think they can do better. >> in 2006, there was a similar investigation and found mass-scale overtime violations it's been six years, and nothing has happened. so i hope they're serious.

>> reporter: how do you know they'll do this? >> there are two reasons. we'll monitor and verify it and report it publicly. but secondly, they made the commitment publicly now. and you guys and the consumers, and the external auditors will watch to see if they deliver. >> in foxconn's statement, they confirm that. our parent companies has strong ties with apple. our ceo sits on their board. there's much more about what the fla found and promises from foxconn to fix them at abc news.com. still ahead, another surveillance tape from that racially charged case in florida. what does it say about trayvon martin's final moms? multi-policy discount. paperless discount. paid-in-full discount.

"nightline" continues from new york city with bill weir. new details tonight on that shooting of florida teenager trayvon martin. george zimmerman's attorney has said his client only pulled the trigger after he was physically attacked and beaten bloody by the young man. but a videotape raises serious questions about that account. matt gutman has been following this story from the start. >> reporter: it was a four-minute encounter. that left one young man dead and another temporarily cuffed and perhaps eternally locked in controversy. he's the neighborhood watchman who shot and killed the 17-year-old trayvon martin, unarmed and carrying iced tea and skittles. tonight zimmerman's brother became the first family member to go on camera, telling cnn's piers morgan, it was a life or death struggle. >> you return force with force.

george was out of breath, barely conscious. his last thing he remembers doing was moving his head from the concrete to the grass. he was very disappointed that none of the neighbors had come out and helped, that the whole situation potentially could have been avoided by just someone coming out and saying, what's going on out there? >> reporter: all along he claimed the boy attacked him, pile-driving him into the ground and slamming his head into the concrete. but in this video 37 minutes after the shooting, no visible sign of blood on his head as a police officer inspects him. but his brother says a month later, zimmerman's nose is still broken. >> it's healing. >> reporter: he files through the station and into this room, the world's first glimpse of his face after that fight. again, no apparent blood.

zimmerman is still in hiding, but his attorney agreed to watch the tape with us. >> does it look like he's beaten up to you? >> i can't tell anything from this video. >> reporter: ultimately he struggled to answer whether or not his client received medical treatment. >> that evidence will all come out when this case is litigated. >> reporter: and this is perhaps where the trayvon martin saga begins. that night, zimmerman walked free. abc news has learned police never bothered to call the person on the phone with martin during his last few moments. >> he said this dude, this white dude looked like he was following him. >> reporter: call logs so that she was on the phone with him starting at 7:12. it was february 26. george zimmerman was on the neighborhood watch and became suspicious of the 17-year-old martin who was walking home from the corner store. he called police. it was raining that night and zimmerman thought there was something off about the 6'1"

black man with a hoodie. >> this guys looks like he's up to no good or on drugs. >> reporter: zimmerman had taken a few law enforcement classes and packed a secret, a pistol. >> are you following him? >> yeah. >> we don't need you to do that. >> he was nervous because he said this man was getting close. >> reporter: zimmerman continues to pursue. martin runs, then slows down, just 70 feet from his back door. >> he asked, why are you following me for? >> reporter: they fight. then the black hole. no eyewitnesses. >> he's a very good kid. he's not disrespectful. he was a regular kid. >> reporter: his face now emblasoned on t-shirts, his name, a rally cry. his clothes, a statement made by politicians. >> just because someone wears a

hoodie, does not make them a hood lum. >> reporter: athletes like the miami heat and celebrities. >> it's a tragedy and it's a shame. and justice needs to be served. >> reporter: to his parents, trayvon was just their boy. >> that was my baby. that was my youngest son. he meant a lot to me. and i don't think the police department really understands that. i feel like i'm a u.s. citizen. i feel like i need justice for my family too. i don't understand why they are protecting him. >> reporter: zimmerman's family also hoping for justice, the two of them linked by those four minutes and the questions they provoke. i'm matt gutman for "nightline" in sanford, florida. >> the saga continues and matt stays on that story. thanks to him. coming up. >> ouch, charlie!

>> one tiny bite for charlie, one giant pay day for charlie's dad. emblazon emblas

do you want to finish it? no. does the baby want to finish it? no.

. so last night, cruising youtube, my little girl became roughly the 436th million person to enjoy charlie bit my finger. much to my delight this morning i came to work and found out that jeffrey kofman has tracked down charlie and his bitten-finger bitten brother and learned how his dad got rich off that minute of spontaneous pain and glee. >> reporter: it's a harry potter birthday party. recognize the birthday boy? he's almost as famous as his favorite wizard. no? well, maybe this will help. >> charlie bit me.

>> that is charlie carr in a video five years ago, the most viewed viral video ever. >> to me, it was such a lovely moment. >> reporter: howard carr posted the clip on youtube in 27, to share with the boy's godfather in colorado. a few months later, he went to remove it and was astonished to see it it had been viewed by almost a million people. >> at first i thought, this is strange r. maybe i should take it down. then i thought, if i take it down, everybody's taken a copy of it and put it on their own website, will just keep those running. >> reporter: his sons are six and eight. do you know how many people watched that? >> three million. >> what do you think? >> eight million. >> reporter: try, 436 million,

with hundreds of goofy parodies. >> they make us laugh. >> reporter: it's like they won the lottery. half a million dollars so far from youtube ads, from tv ads, enough for the boys to attend private schools. it was the viral success of charlie bit me that inspired damian kolier to start a viral video management company. >> i call them accidental content owners because 95% of them have found themselves in this position by mistake, uploading a video to youtube and there they are, all of a sudden owning a valuable piece of copyright. >> reporter: a charlie iphone app is in the works and are so charlie children's books. other owners of viral video are caching in too. a bank used this video to promote paperless statements. an internet security company

uses laughing babies to promote protection. and there's the deer-chasing dog in london, soon to be the subject of a where's waldo-style children's book. >> generally we find animals and babies, like the world over, are popular, and when you look at america's funniest home videos or you've been framed, those tend to be the videos that people can gravitate towards. there's no science to it in truth. >> reporter: but no viral video comes close to the viewership of charlie bit me. do you still bite his fingers? >> he don't let me. >> those teeth look powerful now. no, no, don't -- exactly. thank you very much. charlie just bit my finger. i'm jeffrey kofman for "nightline" in t
