CBS (an initialism of the network’s former name, the Columbia Broadcasting System) is an American English-language commercial broadcast television and radio network that is the flagship property of the CBS Entertainment Group division of ViacomCBS.

The company is headquartered at the CBS Building in New York City with major production facilities and operations in New York City (at the CBS Broadcast Center) and Los Angeles (at CBS Television City and the CBS Studio Center).

The origins of CBS date back to January 27, 1927, with the creation of the “United Independent Broadcasters” network in Chicago by New York City talent-agent Arthur Judson. Its name was changed a year later to Columbia Broadcasting System, Inc., and in 1974 it adopted the name CBS Inc.

CBS is sometimes referred to as the Eye Network, in reference to the company’s trademark symbol, in use since 1951. It has also been called the “Tiffany Network”, alluding to the perceived high quality of CBS programming during the tenure of William S. Paley.

The television network has more than 240 owned-and-operated, and affiliated television stations throughout the United States; some of them are also available in Canada via pay-television providers or in border areas over-the-air. The company ranked 197th on the 2018 Fortune 500 of the largest American corporations by revenue
