YouTube is definitely not your father's method of sharing video footage. The company has amassed a collection of user generated content, thousands of short films and television episodes, and hundreds of full-length movies. Serving more than two billion videos a day, it has become the clear leader in online video sharing. YouTube primarily earns revenue by selling ads on its homepage and search results pages, as well as within its videos. It also charges users to watch certain videos through its YouTube Rentals service. The company was founded in 2005 by Steve Chen (former CTO) and Chad Hurley (former CEO). Today it is a subsidiary of Internet search giant Google.
