CBS (abbreviated from its former name, Columbia Broadcasting System) is an American broadcast television and radio network owned by ViacomCBS through its CBS Entertainment Group division. CBS is sometimes referred to as the Eye Network, in reference to the company's trademark symbol, in use since October 20, 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.

1947–1951
The CBS television network's initial logo, used between 1947 and 1951, consisted of an oval spotlight which shined on the block letters "C-B-S".

1951–present


The present-day Eye device was conceived by William Golden, based on a Pennsylvania Dutch hex sign as well as a Shaker drawing. The Eye device made its broadcast debut on October 20, 1951. The following season, as Golden prepared a new "ident", CBS President Frank Stanton insisted on keeping the Eye device and using it as much as possible. The logo is alternately known as the "Eyemark", which was also the name of CBS's domestic and international syndication division in the mid-to-late 1990s before the King World acquisition and Viacom merger.
