In honor of YouTube’s fifth birthday, the site announced it's now attracting more than two billion video views a day.

“That’s nearly double the prime-time audience of all three major U.S. television networks combined,” the YouTube team wrote in a blog post Sunday. “We certainly can’t imagine what the future will look like. But we do know there’s a lot more to be done ... We’re just getting started.”

To celebrate, the Google-owned site launched its YouTube Five Year Channel and a project called “My YouTube Story,” which features users talking about the ways in which the video site has affected their lives.

Among them are such high-profile users as CBS News' Katie Couric, Internet pioneer Vint Cerf and late-night jokester Conan O'Brien.

In Couric’s video, she says “YouTube is kind of like New York City. Millions and millions of people from all walks of life co-existing in one small space. When you turn the corner, you never know who or what you’ll see.”

Adds O'Brien, "If you're like me, America, you spend an inordinate amount of time watching YouTube - and it's probably why our country's economy is in the toilet."
