Reinforcing its online video presence, CBS is expected to announce on Monday a partnership with Metro-Goldwyn-Mayer Studios Inc., Sony Corp., PBS and Endemol USA to add various television series to its website TV.com.

The new partners will add more than a thousand full episodes or shows supplementing CBS' own programming on the site, which CBS acquired from CNET Networks for as part of a larger deal worth $1.8 billion last year.

We will have content from a number of providers and believe TV.com could become the ultimate TV destination online. Think about the promotion power of our [TV] stations ... it should blow it up into a very significant presence,said Leslie Moonves, CBS' Chief Executive, according to the New York Times.

CBS aims to differentiate itself from the competition by emphasize user interactions with TV.com. The site will be going against a pair of tough competitors in Youtube.com owned by Google Inc., and Hulu.com launched by NBC Universal and News Corp.

The site had 16 million unique visitors in November, according to internet measurement firm comScore

Before getting any content from CBS, TV.com had 16.5 unique visitors, according to Moonves.
