Confirming the rumors, Microsoft says it will start selling downloadable television shows for its Zune device -- including selected programs from NBC, the network that split from market leader Apple.

The move comes more than two years after Apple introduced television shows and movies for its dominant iTunes store and iPod -- reflecting Zune's latecomer status. Microsoft launched the device in late 2006, after devices from its hardware partners struggled to gain any significant traction against Apple's iPod.

Microsoft says its Zune online store will add television shows starting Tuesday, offering about 800 episodes initially. The episodes will cost the equivalent of $1.99 in Microsoft "points." The company requires consumers to first buy points that they can apply to online purchases.

NBC had been a significant provider of content to Apple's iTunes store, which works in conjunction with the iPod, but the companies split last year after a disagreement over pricing. Microsoft said it will offer shows including NBC programs "The Office," "Heroes," and "30 Rock."

Other TV shows to be available for the Zune will include Comedy Central's "South Park," the SciFi Channel's "Battlestar Galatica,"and VH1's "Rock of Love with Bret Michaels."
Zune devices had already been capable of playing video, including video podcasts and music videos, but the Zune online store has until now concentrated largely on music.

"This is a first step into the (television) market for us," said Jason Reindorp, Zune product marketing director, explaining Microsoft's decision to launch with a selected library of shows. Microsoft "will be adding to that significantly over time," he said.

Separately, Microsoft already sells TV shows and movies for download and viewing on its Xbox 360 video-game consoles. Reindorp said shows to be available through the Zune store won't be able to be played directly on any other device but a Zune or a PC, although a Zune can connect to a TV or an Xbox 360 to stream content for viewing.
