All-news radio is a radio format devoted entirely to discussion and broadcast of news.

All-news radio is available in both local and syndicated forms, and is carried in some form on both major US satellite radio networks. Some all-news stations, like KYW, WBBM and WCBS, carry sports, and all-news stations may occasionally carry public affairs programs, simulcasts of TV news magazine or political affairs shows like 60 Minutes and Face the Nation, and national radio shows revolving around news such as the CBS News Weekend Roundup. Some all news stations, like KNX and WBZ, run talk radio programs on weekends and during off peak hours, while WBBM also carries programming revolving around the NFL Chicago Bears, as that station airs the play-by-play for the team. Some CBS news radio stations also air When Radio Was in the overnight hours, a nightly program featuring rebroadcasts of old time radio. Most of these stations are owned by CBS Radio, and therefore are affiliated with the CBS Radio network.

ABC News is the news gathering and broadcasting division of the American Broadcasting Company, a subsidiary of The Walt Disney Company. Its flagship program is World News with Diane Sawyer; other programs include morning show Good Morning America, Nightline, television news magazine shows Primetime & 20/20, and Sunday morning political affairs program This Week with George Stephanopoulos.

ABC began news broadcasts early in its independent existence as a radio network after the Federal Communications Commission ordered the former NBC Blue Network to be spun off as an independent company in 1943. This was done to keep single or a few companies such as NBC and CBS from dominating radio broadcasting in the U.S., and in particular, from dominating news and political broadcasting and projecting narrow points-of-view. Television broadcasting was suspended however, during World War II.

Regular ABC television news broadcasts began soon after ABC started transmitting from its initial New York City television station and production center in late summer 1948. ABC-TV news broadcasts have continued as the ABC television network spread across the country, a process that took many years, from that beginning in 1948 through today, but they have not always had the same level of success that they enjoy now. Throughout the 1950s, the 1960s, and the early 1970s, ABC News consistently ranked third in viewership behind CBS News and NBC News. Until the 1970s, the ABC-TV network had fewer affiliate stations, and also weaker prime-time programming lineups to support the network's news departments than the two larger networks had, each of which had established their radio news operations during the 1930s.
