Mega net ABC will offer full episodes of Lost, Desperate Housewives and Commander In Chief online for free beginning in May. The net is experimenting with a new digital on-demand model that will allow viewers to watch an episode a day after it runs on conventional TV. Viewers will also be able to pause, rewind and fast forward through the eps – but will not be able to skip through the ads. And the ads streaming online during the ep aren’t necessarily going to be the same ones that ran the night before during the show’s scheduled run. This new model is expected to help stimulate viewership of the traditional broadcast, with the Web offering additional eyeballs. Content from some of the cable’s channels including the Disney Channel, ABC Family and Soapnet will also be carried on the service.
