NBC announced today that they will be launching a new service called "NBC Direct" which will allow users to download and view NBC's popular primetime shows to their desktops for free and watch them for up to one week after broadcast.

The first version of this software will launch in October for Windows PCs only, but "future versions" are said to add Mac compatibility.

At launch the shows will include "Heroes," "The Office," "Life," "Bionic Woman," "30 Rock," "Friday Night Lights," "Late Night with Conan O'Brien" and "The Tonight Show with Jay Leno."

In 2008, NBC plans to offer expanded sales options which could include download-to-own, rental and subscription models.

NBC recently withdrew from future iTunes distribution of their television shows due to a contract dispute with Apple.
