CBS News Radio, formerly known as CBS Radio News and historically known as the CBS Radio Network, provides news to more than 1,000 radio stations throughout the United States. The network is owned by ViacomCBS. It is the last of the three original national U.S. radio networks (CBS, NBC Radio Network and Mutual Broadcasting System) still operating and still owned by its parent company, even though CBS sold its owned and operated radio stations in 2017. (The current NBC Radio Network is actually owned by iHeartMedia but licenses use of the NBC name and NBC's TV news reports.)
