The number of U.S. broadband households watching premium online content, including movies and TV shows via the Internet, doubled in the last year, according to Broadband, Communications, and Entertainment Bundles, a new study from Parks Associates. Currently over 25 million U.S. broadband households regularly watch full-length TV shows online, while over 20 million watch movies online.

The international research firm reports that the growing popularity of online portals such as Hulu.com shows rapid growth in the number of viewers who use the Internet to watch long-tail and premium content. This shift highlights the opportunity for service providers to extend their current pay-TV and video-on-demand services to include online and mobile video features. In fact, providers will have to embrace online video services, including the ability to deliver content across multiple platforms, if they are to remain competitive and attract new subscribers.

The next step, according to Dasari, is for content owners and distributors to come to a consensus on business models so they can monetize consumer interest in online media.
