The shows will include advertising that cannot be skipped over during viewing. ABC, which is owned by The Walt Disney Co., already offers ad-free episodes for $1.99 each on Apple Computer Inc.'s iTunes store.
The offerings on the ABC.com Web site will also include current episodes of "Commander in Chief," as well as the entire season of "Alias," and will be available through June. New episodes will be available online the day after they run on ABC.
ABC has not made shows available on Google's video store. ABC has also not yet signed any agreements with cable companies to distribute its hit prime-time shows for on-demand replay services offered on cable, although Sweeney said they were in active talks with several providers.
