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 a flagship property of CBS Corporation. 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).
CBS HD is sometimes referred to as the Eye Network, in reference to the company’s iconic 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. It can also refer to some of CBS’s first demonstrations of color television, which were held in a former Tiffany & Co. building in New York City in 1950.
