Although YouTube's birthday is officially February 14, 2005, the first video was actually uploaded to the site exactly five years ago, on April 23, 2005. The video is titled Me at the zoo.. It was shot by Yakov Lapitsky and it's only 19 seconds long, showing one of YouTube's founders, Jawed Karim, at the San Diego Zoo. The video doesn't look like much, but it sparked a revolution; by July 2006, more than 65,000 videos were uploaded to the site every day.
