Chad Hurley, Steve Chen, Jawed Karim, 2005

If you have never heard of YouTube, you either live under a rock or you simply hate videos. The video-sharing Web site was created by three former PayPal employees in 2005. Chad Hurley, Steve Chen and Jawed Karim invented YouTube out of a garage in Menlo Park, California. It caught on almost immediately. In 2006 there were 100 million videos in YouTube’s searchable archive. YouTube is still immensely popular and most of the content is uploaded by individuals. Me at the zoo was the first video on YouTube and shows co-founder Jawed Karim at the San Diego Zoo.
