Under the name Group W, it had been one of the major broadcasting group owners of commercial radio and television stations since 1920 and was seeking to transition from a station operator to a major media company with its purchase of CBS. Except for KUTV, which CBS sold to Four Points Media Group in 2007 and which is now owned by the Sinclair Broadcast Group, all of the stations involved in the initial Westinghouse deal as well as WWJ-TV remain owned-and-operated stations of the network to this day. Westinghouse's acquisition of CBS turned the combined company's all-news radio stations in New York City (WCBS and WINS) and Los Angeles (KNX and KFWB) from bitter rivals to sister stations. While KFWB switched from all-news to news/talk in 2009, WINS and WCBS remain all-news stations. WINS, which had pioneered the all-news format in 1965, generally restricts its news coverage to the five core New York City boroughs, while WCBS, with its much more powerful signal, covers the surrounding tri-state metropolitan area. In Chicago, Westinghouse's WMAQ began to feature long-form stories and discussions about the news. It often focused on business news so as to differentiate itself from WBBM. This lasted until 2000, when an FCC ownership situation resulted in CBS Radio's decision to move its all-sports network WSCR to WMAQ's signal and to sell off the former WSCR facility. In 1997, Westinghouse acquired the Infinity Broadcasting Corporation, which owned more than 150 radio stations, for $4.9 billion. Also that year, Westinghouse created a new division known as CBS Cable, which was formed upon the acquisition of two existing cable channels from the Gaylord Entertainment Company, namely The Nashville Network (now Spike) and Country Music Television, and the creation of a new channel, namely CBS Eye on People, which was later sold to Discovery Communications. CBS also owned the Spanish-language news network CBS Telenoticias. Following the Infinity purchase, operation and sales responsibilities for the CBS Radio Network were handed to Infinity, which turned management over to Westwood One, a major radio program syndicator that Infinity managed. Westwood One had previously purchased the Mutual Broadcasting System, NBC's radio networks, and the rights to use the "NBC Radio Networks" name. For a time, CBS Radio, NBC Radio Networks, and CNN's radio news services were all under the Westwood One umbrella. , Westwood One continues to distribute CBS radio programming, but as a self-managed company that put itself up for sale and found a buyer for a significant amount of its stock.
