CBS and Time Warner Cable finally reached a deal on Monday, ending a long, protracted blackout of the broadcast network on TWC’s cable system. While getting the deal done will mean that Time Warner Cable viewers will be able to watch Week One of the NFL season next week — and no one wanted to miss that — the deal is also designed to help CBS monetize its content on a growing number of new platforms. Increasingly, agreements between networks and cable operators are getting hung up on the question of digital rights whenever those contracts come up. In the case of CBS, the network has been pretty cautious about how viewers watch its shows on their computers and on other devices. While the other broadcasters made their content available through Hulu and Hulu Plus, CBS forced viewers to watch its shows on CBS.com.
