Since its inception in 2005, YouTube has become a global phenomenon. Last year, the site reported an average of 4 billion views per day, nearly four times the prime-time audience for all three major U.S. television networks combined. That's a lot of video watching, and not all of it has been concentrated on classics like "Charlie Bit My Finger" (now with more than half a billion views, the most of any user-submitted video) and funny videos of cats. There's also a significant market out there for videos focusing on education, an audience that YouTube itself has worked to cater to over the past few years. These changes have helped bring the Google-owned video site into the forefront of educational technology, and with the popularity of its educational content rising at a rapid clip, it's unlikely to lose that status anytime soon. To commemorate YouTube's committment to delivering educational content, here's a quick look back at some of the pivotal moment in the site's history that have made it such an educational powerhouse today.
