According to a post at BetaNews.com, CBS programming will be coming soon to iTunes. "CBS Digital Media president Larry Kramer confirmed the news in an interview with financial site MarketWatch. The plans to offer shows on iTunes is part of a larger initiative aimed at attracting new viewers by providing access to the network's programming in a variety of formats."
For now, CBS is looking to sell episodes of "Survivor" on its own for $1.99 per show, and only on a rental type of system where downloaded material would expire 24 hours after ordering. This is different from Apple's pay once-watch forever download model.
