Radio or television broadcast of news events. News gathering and broadcasting by the radio networks began in the mid-1930s and increased significantly during World War II. The television newscast began in 1948 with 15-minute programs that resembled movie newsreels. The current U.S. format employs a newscaster or anchorperson reading news stories, with interpolated audiotape (for radio) or videotape (for television) and live reports from remote journalists. Noted newscasters have included Edward R. Murrow, Walter Cronkite, and David Brinkley.
