CBS News Radio will end its service on May 22, bringing to a close nearly a century of radio news broadcasting that helped establish the standards for American journalism.

Founded in the 1920s, CBS Radio News became a pioneering force in broadcast journalism, featuring legendary correspondents including Edward R. Murrow, Robert Trout, and Charles Osgood. The service created what many consider the template for modern broadcast journalism.

Edward R. Murrow became particularly renowned for his World War II coverage, bringing immediate and empathetic reporting of the war directly into American homes. His broadcasts covered major events from the London Blitz and the Allied invasion of Europe to the liberation of Buchenwald concentration camp, helping listeners understand distant events through vivid reporting.

The radio service influenced generations of journalists, including Dan Rather, who has spoken about CBS Radio News' impact on his development as both a listener growing up in Texas and later as a young journalist learning from "Murrow's Boys." Rather went on to become a veteran radio correspondent and former anchor of the CBS Evening News.

Current and former CBS staffers, including Sunday Morning correspondent Martha Teichner, who reported on radio for decades, have reflected on the service's long history and its role in shaping broadcast journalism standards that continue today.
