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.
