CBS

CBS Broadcasting Inc., commonly shortened to CBS (an abbreviation of its original name, the Columbia Broadcasting System), is an American commercial broadcast television and radio network and the flagship property of the CBS Entertainment Group division of Paramount Skydance following the 2025 merger of Paramount Global, National Amusements and Skydance Media. It is one of Paramount Skydance's three flagship subsidiaries, along with partial namesake Paramount Pictures and MTV.

Founded in 1927, headquartered at the CBS Building in New York City and being part of the "Big Three" television networks, CBS has major production facilities and operations at the CBS Broadcast Center and One Astor Plaza (both also in that city) and Television City and the CBS Studio Center in Los Angeles. It is sometimes referred to as the Eye Network, after the company's trademark symbol of an eye (which has been in use since October 20, 1951), and also the Tiffany Network, which alludes to the perceived high quality of its programming during the tenure of William S. Paley (and can also refer to some of CBS's first demonstrations of color television, which were held in the former Tiffany and Company Building in New York City in 1950).

The network has its origins in United Independent Broadcasters, Inc., a radio network founded in Chicago by New York City talent agent Arthur Judson on January 27, 1927. In April of that year, the Columbia Phonograph Company, parent of Columbia Records' record label, invested in the network, resulting in its rebranding as the Columbia Phonographic Broadcasting System (CPBS). In early 1928, Judson and Columbia sold the network to Isaac and Leon Levy, two brothers who owned WCAU, the network's Philadelphia affiliate, as well as their partner Jerome Louchheim. They installed William S. Paley, an in-law of the Levys, as president of the network. With the Columbia record label out of ownership, Paley rebranded the network as the Columbia Broadcasting System.

By September 1928, Paley became the network's majority owner with 51 percent of the business. Paramount Pictures then acquired the other 49 percent of CBS in 1929, but the Great Depression eventually forced the studio to sell its shares back to the network in 1932. CBS would then remain primarily an independent company throughout the next 63 years. Under Paley's guidance, CBS would first become one of the largest radio networks in the United States and eventually one of the Big Three American broadcast television networks. CBS ventured and expanded its horizons through television starting in the 1940s, spinning off its broadcast syndication division Viacom to a separate company in 1971. In 1974, CBS dropped its original full name and became known simply as CBS, Inc.

The company was listed on the New York Stock Exchange under the ticker symbol "CBS". The Westinghouse Electric Corporation acquired the network in 1994, renaming its legal name to the current CBS Broadcasting Inc. two years later, and in 1997 adopted the name of the company it had acquired to become CBS Corporation. In 1999, CBS came under the control of the original incarnation of Viacom, which was formed as a spin-off of CBS in 1971. In 2005, Viacom split itself into two separate companies and re-established CBS Corporation through the spin-off of its broadcast television, radio and select cable television and non-broadcasting assets, with the CBS network at its core. CBS Corporation was controlled by Sumner Redstone through National Amusements, which also controlled the second incarnation of Viacom until December 4, 2019, when the two separated companies agreed to re-merge to become ViacomCBS (now known as Paramount Global). Following the sale, CBS and its other broadcasting and entertainment assets were reorganized into a new division, CBS Entertainment Group.

CBS operated the CBS Radio network until 2017 when it sold its radio division to Entercom (now known as Audacy, Inc. since 2021). Before this, CBS Radio mainly provided news and feature content for its portfolio of owned-and-operated radio stations in large and mid-sized markets, as well as its affiliated radio stations in various other markets. While CBS Corporation common shareholders (i.e. not the multiple-voting shares held by National Amusements) were given a 72% stake in the combined Entercom, CBS no longer owns or operates any radio stations directly; however, it still provides radio news broadcasts to its radio affiliates and the new owners of its former radio stations, and licenses the rights to use CBS trademarks under a long-term contract. The television network has over 240 owned-and-operated (O&O) and affiliated television stations throughout the United States, some also available in Canada via pay-television providers or in border areas over-the-air.

As of 2025^[update], CBS provides 87+1⁄2 hours of regularly scheduled network programming each week. The network provides 22 hours of primetime programming to affiliated stations Monday through Saturday from 8:00 p.m. to 11:00 p.m. and Sunday from 7:00 p.m. to 11:00 p.m. Eastern and Pacific time (7:00 p.m. to 10:00 p.m. Monday through Saturday and 6:00 p.m. to 10:00 p.m. on Sunday in Central/Mountain time).

The network also provides daytime programming from 11:00 a.m. to 4:00 p.m. Eastern and Pacific weekdays (subtract 1 hour for all other time zones), including a half-hour break for local news and features game shows The Price Is Right and Let's Make a Deal and soap operas The Young and the Restless, The Bold and the Beautiful, and Beyond the Gates.
