Time Warner Cable customers in several major U.S. cities, including New York, Los Angeles and Dallas, have been without CBS programming since Friday, when negotiations over retransmission fees broke down. And now, thanks to a decision by CBS, those viewers andcustomers will feel squeezed out online: The network has decided to block them from accessing programming that would normally be available on the Internet, as well.

"If Time Warner Cable is a customer's Internet service provider, then their access to CBS full episode content via online and mobile platforms has been suspended as a result of Time Warner Cable's decision to drop CBS and Showtime from their market," CBS spokesperson Dana McClintock told TODAY.com.

"As soon as CBS is restored on Time Warner Cable systems in affected markets, that content will be accessible again," she added.

That said, some TWC customers are still able to access CBS.com programming -- at least for now. As the spokesperson noted, "There are some instances where TWC customers have reported being able to watch. It's not 100%."
