Comcast and CBS have announced that eight of CBS’ primetime series will now be available at no cost through its VOD (video-on-demand) service. The shows included are CSI: Crime Scene Investigation, CSI: NY, CSI: Miami, NCIS, Big Brother, Survivor, Jerico and Numb3rs.

Previously, Comcast had allowed viewings for $.99 per episode on CBS owned and operated stations. These “free” episodes will now contain commercials sold by CBS. Available to all On Demand viewers beginning the day after network airing, they will be viewable for four weeks. Considering that you can already watch those full episodes without commercial interruption at no charge on the CBS Website (via innertube), us non-subscibers can go there to play catch-up or just survive until the reruns.
