software updates overnight

Microsoft Corp. said late Monday it will now sell TV shows, including popular NBC series, on the Zune Marketplace, a move that brings its selection of content for the digital media player a step closer to what Apple Inc.'s iTunes offers for Apple's much more popular iPod.

Redmond, Wash.-based Microsoft said it also planned to send out software updates overnight that add new features to the Zune devices and the PC software used to buy and manage digital content.
