The Internet provides access to copious free video content that people never would have dreamed of a few years ago. But it comes with a catch. Hulu lets you watch the latest episodes of your favorite TV shows, anytime, for weeks after they air. But interspersed throughout, they insert an increasing number of commercials, just like regular television. YouTube has tons of original web content, the latest hit pop songs and music videos and much, much more. But before you can watch your one-minute video, most times first you have to watch a 30-second ad.
