What began as a live video "lifecast" of Yale graduate Justin Kan in 2005 has grown into a platform that lets anyone produce his or her own live broadcasts over the Web. Each month, some 35 million people watch Justin.tv videos, which range from live coverage of sports and music events to streaming footage of puppies. The 15-person company expects to take in $5 million in revenues this year—mostly from users who pay $10 per month for "pro accounts," which allow them to watch video on the site during peak hours in certain countries, where access would otherwise be limited.
