CBS News is the news division of the American television and radio broadcaster CBS, one of the 'big three' broadcast networks in the United States alongside ABC News and NBC News. Established as part of CBS, which began operations on September 25, 1927, as the Columbia Broadcasting System, the news division was formally organized in March 1933 when Paul White was appointed vice president and general manager in charge of news. It delivers journalism through television, radio, and online platforms with a focus on in-depth reporting. It has built a reputation for reliable reporting on events of public concern such as political conventions and elections, and is known for investigative journalism including the controversial 2004 Killian documents story on CBS's 60 Minutes II, which questioned President George W. Bush's service in the Texas Air National Guard. The organization has undergone several corporate transformations, including the 1995 acquisition by Westinghouse Electric Corporation (which later became CBS Corporation) and the 2019 combination with Viacom to form ViacomCBS (later Paramount Global), under which CBS News operates today. CBS News produces flagship programs like CBS Evening News, Face the Nation, and 60 Minutes, and extends to local stations through CBS News and Stations. Headquartered in New York City, CBS News maintains a vast network of correspondents and bureaus, emphasizing both national and international coverage. It has faced criticisms over the years for perceived biases and errors, but remains a cornerstone of American broadcast journalism with a legacy of award-winning reporting.
