CBS announced today that it will buy another station, a move that will give the network a duopoly in the nation’s No. 1 media market.

CBS plans to buy New York station WLNY-TV. The network already owns WCBS-TV in the New York market, CBS’s flagship station. Terms of the deal to buy independent station WLNY were not disclosed.

WLNY — whose call letters reportedly stand for We Love New York — is distributed by cable, satellite and other service providers in areas of New York, New Jersey and Connecticut, appearing as either Channel 10 or Channel 55 on most channel lineups and as Channel 55 as an over-the-air service.

Said Peter Dunn, president of CBS Television Stations: "The combined strengths of CBS 2 and WLNY-TV will give us a terrific platform for serving the entire New York area."

The network said it plans to add personnel and resources to widen WLNY’s local news coverage beyond its current nightly half-hour.

Added Dunn: "And, of course, in doing so we will continue to honor the station’s already deep commitment to serving the people of Long Island and the entire tri-state area. We also look forward to having a bigger and better news bureau on Long Island that will be a terrific resource for WCBS."
