YouTube is definitely not your father's method of sharing video footage. The company has amassed a collection of more than 100 million video clips, many of which feature user generated content, which it broadcasts online via its Web site at YouTube.com. With about 70 million unique visitors a month in the US (and the sixth largest audience on the Web), it has become the clear leader in online video sharing. YouTube earns revenue by selling advertising, and has partnership deals with content providers such as CBS, Warner Music Group, and the NBA. YouTube is a subsidiary of Internet search giant Google.
