You can pay a buck nine nine to download "Desperate Housewives," "Lost," and "Commander in Chief" from the iTunes Music Store. Or starting next month, you can watch them for free on the Internet. ABC has announced plans to stream these three shows, along with "Alias," on its Website the day after they air on TV. Unlike the iTunes shows, though, they will include commercials that, according to ABC, can't be skipped. Looks like bosses and network admins better watch out for the onslaught of workers watching TV during the day.
