2.Justin Kan and Emmett Shear:

By the time these two entrepreneurs celebrated their 25th birthday, they both were successful in starting up their own web companies. During their senior year at Yale University, they both launched the first calendar program called Kiko. Unfortunately, these two co-founders had to sell Kiko on Ebay for a low price after Google came up with a similar platform. Later, they did not take much time to come up with a new idea where Kan would attach a camera to his head and by that he started recording every moment of his life for an indefinite period of time. This fresh and innovative idea led to Justin.TV, where the site which was created for users to upload their own live broadcasts.At present, thousands of web videographers post on the site each day.
