CBS, Yahoo Share Comedy Online

Joining the trend of TV shows migrating to the Internet, Yahoo! will host a pair of episodes from CBS comedies "Two and a Half Men" and "How I Met Your Mother" for free video streaming this week.

Available now through next Monday, these half-hours (which aired earlier this season) will be available in their entirety and without commercials, CBS and Yahoo! announced. It marks the first time that the Sunnyvale, Calif.-based company is streaming episodes of a CBS television series in their entirety.

The episodes of "Two and a Half Men" (which stars Charlie Sheen, Jon Cryer and Angus T. Jones) are "We Called It Mr. Pinky" and "Madame and Her Special Friend."

The episodes of "How I Met Your Mother" (a freshman entry whose stars include Alyson Hannigan, Neil Patrick Harris and Josh Radnor) are "The Pineapple Incident" and "The Sweet Taste of Liberty."

Both shows are regularly broadcast on CBS Monday nights.

These special Webcasts are part of a growing movement of TV shows being made available to viewers through streaming video on their computers or via downloads to other devices.

For instance, with the recent introduction of Apple's video iPod, ABC began making available reruns of series including "Lost" and "Desperate Housewives" for download to iPods at $1.99 per episode. NBC offers same-night replay of "Nightly News" online at no charge.

TiVo has announced that, starting next year, it will offer any show recorded on its digital video recorder for downloading to an iPod. And AOL will soon make available episodes from some 30 classic TV series for viewing on an online AOL channel.
