CBS enters a new age of TV

In an effort to improve its demographic base, CBS announced Wednesday that it is scrapping Diagnosis Murder, starring 75-year-old Dick Van Dyke, and Walker, Texas Ranger, starring 61-year-old Chuck Norris. Dropping each of the 8-year-old shows will result in making CBS’s fall schedule “a lot younger, a lot more affluent,” CBS chief Les Moonves said Wednesday in presenting the network’s fall schedule. CBS currently attracts more 50+ adults than any other network and the fewest number of 18-49-year-olds. Moonves also said that the next Survivor series will debut in October in the same Thursday-night time period as it did last month — opposite NBC’s Must-See-TV lineup.
