YouTube: LonelyGirl15 Returns for 10th Anniversary

Engadget: Lonelygirl15, the first web series on YouTube, turned 10 on June 16. To celebrate the event, its creators posted a new video eight years after its last one. Everybody knows the terms “web series” and “viral video” these days, but back in 2006, they still weren’t a thing. YouTube was just a fledgling video-sharing website, and Lonelygirl15 helped shape it into what it has become today.
