When former PayPal employees Chad Hurley, Steve Chen and Jawed Karim first came up with the idea to create a video-sharing site in 2005, they had no clue just what would unfold years later.

On Feb. 14 that year, YouTube was launched, and on April 23, an 18 second clip uploaded by Karim titled "Me at the zoo" became the site's very first shared video.

Ten years down the road, YouTube has become a global phenomenon with over 1 billion users and 300 hours of video uploaded onto the site every minute.
