CBS looks to be ready to start selling at least some TV shows through the iTunes Store for US$0.99, or half the current price networks are charging. The move is part of an experiment to see if sales increase, although networks are skeptical at the likelihood of success, according to the New York Times.

"We're willing to try anything, but the key word is 'try,' " commented one anonymous TV network executive.

Presumably, the networks will be open to keeping TV show prices lower at the iTunes Store if customers start buying more, although for now it appears that only standard definition quality shows will see a price cut. HD versions of TV shows will stay priced at $2.99 each.

Not everyone, however, plans to keep show prices lower. PBS, for example, is offering several shows for $0.99 right now, but plans to bump the prices back up to $1.99 in three week. PBS senior vice president Andrew Russell said their price reductions were an experiment to "generate buzz."

While CBS has committed to selling shows for under a dollar, it hasn't decided yet which ones will see the price cuts.
