Christopher Glenn, an award-winning CBS News radio and television correspondent, died Tuesday of liver cancer. He was 68.

Mr. Glenn was best known as the voice of “In the News,” a short TV news segment for children in the 1970s and 1980s. He retired in February after 35 years with the company and was to be inducted Nov. 4 into the Radio Hall of Fame in Chicago, an honor he will receive posthumously.

Mr. Glenn joined CBS as a radio producer for special events. His radio work won him many national awards, the last of which was from the Radio-Television News Directors Association, a 2005 Edward R. Murrow award for best newscast.

He was named a television correspondent in 1976 and came back to radio in January 1984. He anchored and reported on many national stories, including space shuttle missions, and served as a floor reporter at national political conventions.

The Emmy-winning “In the News,” a 2.5-minute feature on a single news topic, was broadcast every half-hour during Saturday children’s programming on CBS. It debuted in September 1971 and ran for 5,000 episodes over 13 seasons, with Mr. Glenn as its reporter and narrator.
