There's no denying that YouTube is easily the biggest player in sharing video on the internet. It came just at the right time and was available to the right people to make it great. With it evolving massively since 2005, it's become the number 1 destination for video content on the web. It has its own partner program whereby it pays content creators for making videos which get a lot of views via ads. Many people actually live off the partnership program and create YouTube videos for a living.
