Primetime programming from CBS is now available on iTunes. Shows available for purchase and download include Survivor, Numb3rs, NCIS and CSI: Crime Scene Investigation, CSI: Miami, and CSI: NY.

The new CBS offerings include episodes from the just-completed 2005/2006 season, and earlier for some series, as well as the upcoming season, which starts in September. New episodes in the fall will be available on iTunes the day after they appear on the network.

Earlier this year, CBS Sports made the 2006 NCAA Men's Basketball Tournament available on iTunes, and Showtime, which is a division of CBS Corporation, brought iTunes customers two of their most popular series: Sleeper Cell and Weeds.
