Of course, our children and our children's children will never need to dig up an actual time capsule to find out about the wardrobe malfunction. As soon as they hear about the time Janet Jackson's breast was exposed on live TV, they'll watch it online. And the reason they'll watch it online is that in 2004, Jawed Karim, then a 25-year-old Silicon Valley whiz kid, decided he wanted to make it easier to find the Jackson clip and other in-demand videos. A year later, he and a couple of friends founded YouTube, the largest video-sharing site of all time.

Across the web, the moment went viral, back when that phenomenon was still somewhat novel. (Facebook was launched three days after the halftime show.) "Janet Jackson" became the most searched term and image in Internet history. And "we put TiVo on the map," says MTV producer Coletti — TiVo enrolled 35,000 new customers in the aftermath of Nipplegate. When Coletti was having trouble with his service, he let slip to a customer service rep that he was the guy who produced the Super Bowl halftime show. TiVo gave him lifetime service and a special number to call in case he had any trouble.
