In the age of online entertainment, consumers get virtually unlimited choice of content and unlimited means to entertain themselves. They can stream their favorite episode of “Lost” from ABC.com, watch full-length movies on Hulu or even download episodes of shows like the “The Office” from NBCDirect, and they can do it all for free. These choices offer consumers an unprecedented amount of control over their entertainment experience, which is bad news for incumbent content aggregators: cable, satellite and IPTV companies.
