# Viacom (1952–2005)

Viacom Inc. (derived from "Video & Audio Communications") was an American mass media and entertainment conglomerate based in New York City. It began as CBS Television Film Sales, the broadcast syndication division of the CBS television network in 1952; it was renamed CBS Films in 1958, renamed CBS Enterprises in 1968, renamed Viacom in 1970, and spun off into its own company in 1971. Viacom was a distributor of CBS television series throughout the 1970s and 1980s, and also distributed syndicated television programs. The company came under Sumner Redstone's control in 1987 through his cinema chain company National Amusements.
At the time of its split, Viacom's assets included the CBS and UPN broadcast networks, the Paramount Pictures film and television studio, local radio station operator CBS Radio, cable channels such as MTV, Nickelodeon, Comedy Central, BET and Showtime, outdoor media operator Viacom Outdoor, television production and distribution firm King World Productions, and book publisher Simon & Schuster. It also owned its IP holding subsidiary Viacom International and brand licensor Westinghouse Licensing Corporation.
In 2000, Viacom acquired the parent company of CBS, the former Westinghouse Electric Corporation, which had been renamed CBS Corporation in 1997. Viacom was split into the second incarnations of CBS Corporation and Viacom in 2005, which both being controlled by National Amusements; the split was structured with the second CBS Corporation being the original Viacom's legal successor, and the second Viacom being an entirely new company. The two companies eventually re-merged in 2019, leading to the formation of ViacomCBS, now known as Paramount Global. As of 2025, Paramount and National Amusements are in a 3-way merger with Skydance Media.

## History

Viacom originated on March 16, 1952 — when CBS founded its broadcast syndication division, CBS Television Film Sales. It renamed as CBS Films in October 1958. On December 1, 1967, it again renamed as CBS Enterprises Inc.. On July 6, 1970, it announced that CBS Enterprises would be spun out from its parent company, and the same month the division was incorporated as Viacom, and spun off on January 1, 1971, amid new FCC rules forbidding television networks from owning syndication companies (the rules were later repealed).
Viacom expanded its activities throughout the decade with a launch of a production unit, and later acquired the rights to various features from various studios.
In addition to CBS TV series syndication rights, Viacom also held cable systems with 90,000 cable subscribers, at that time the largest in the US. In 1976, Viacom launched Showtime, a pay movie channel, with Warner-Amex taking a half-share ownership. The company went into original programming production starting in the late 1970s until the early 1980s with middling results. The company expanded in 1977 to launch a unit for program acquisitions and prime-time network programming.

### Expansion through acquisitions

Viacom's first broadcast station acquisition came in 1978 when the company purchased WHNB-TV in New Britain, Connecticut, changing its call letters to WVIT. Two years later Viacom added the Sonderling Broadcasting chain, giving it radio stations in New York City, Washington, D.C., Houston, and San Francisco, and one television station, WAST (now WNYT) in Albany, New York.
In 1983, Viacom purchased KSLA in Shreveport, Louisiana, and WHEC-TV in Rochester, New York, in separate transactions. This was followed in 1986 with CBS-owned KMOX-TV in St. Louis; with the purchase, that station's call letters were changed to KMOV.
Also in 1983, Viacom reacquired its premium channel Showtime, and later merged it with Warner-Amex's The Movie Channel forming Showtime/The Movie Channel, Inc. Between the late 1980s and the early 1990s, Viacom syndicated several shows produced by Carsey-Werner Productions, namely The Cosby Show, A Different World and Roseanne.
In 1985, Viacom acquired Showtime/The Movie Channel, Inc. from Warner-Amex, ending the joint venture. Around the same time, Viacom bought MTV Networks, which owned MTV, VH-1, and Nickelodeon. This led to Viacom becoming a mass media company rather than simply a distribution company, and completed in 1986.
In 1987, Viacom sought to expand its horizons by launching the new Viacom Network Enterprises division, which was led by Ronald C. Bernard, in order to develop and exploit properties outside of the core cable business and the company would ride herd on diverse enterprises as Viacom's pay-per-view venture, Viewer's Choice, Satellite Direct, Inc. and SMA TV, and handle strategic planning and new business development for Viacom Networks Group, and would develop merchandising, licensing and home video business around the two Viacom subsidiaries it was currently operating, Showtime-The Movie Channel, Inc. and MTV Networks.
In 1989, the company had set up its own division Viacom Pictures, to produce its feature films for television, most notably Showtime.
Sumner Redstone, via his theater chain operator National Amusements, acquired a controlling interest in Viacom on June 10, 1987. Redstone made a string of large acquisitions in the early 1990s, announcing plans to merge with Paramount Communications (formerly Gulf+Western), parent of Paramount Pictures, in 1993, and buying the Blockbuster Video chain in 1994. The acquisition of Paramount Communications on July 7, 1994, made Viacom one of the world's largest entertainment companies. Also in 1993, WTXX entered into a part-time local marketing agreement with Viacom's NBC station WVIT.
The Paramount and Blockbuster acquisitions gave Viacom access to large television holdings: An archive of programming controlled by Aaron Spelling's company which included, along with his own productions, the pre-1973 ABC and NBC libraries under Worldvision Enterprises and Republic Pictures; and an expanded group of television stations which merged Viacom's five existing outlets into Paramount's seven-station group. Viacom used some of these stations to launch the UPN network, which started operations in January 1995 as a joint venture with Chris-Craft Industries. Shortly afterward, Viacom/Paramount spent the next two years selling off its non-UPN affiliated stations to various owners. In 1997, Viacom exited the broadcast radio business, albeit temporarily, when it sold the majority of its stations to Chancellor Media, a predecessor company of iHeartMedia.
On September 7, 1999, Viacom announced their acquisition of CBS Corporation in a $35.9 billion deal. In addition to being the largest media merger in history at the time, the purchase effectively reunited Viacom with its former parent, CBS. The merger was completed in May 2000, bringing CBS's cable channels TNN (now Paramount Network) and Country Music Television (CMT) under Viacom's MTV Networks wing, as well as CBS's production and distribution units Eyemark Entertainment (formerly Group W Productions) and King World under the main wing. The merger also folded Viacom's broadcast group, now consisting entirely of UPN stations, into CBS's owned-stations division.
In 2001, Viacom completed its purchase of BET Holdings, the owners of the Black Entertainment Television (BET) network. As with CBS Cable, it was immediately integrated into MTV Networks, causing some outcry among BET workers in the Washington, D.C., area (where BET was based before the merger). As a result, BET was separated from MTV Networks, into a division known as BET Networks.
Although a majority economic interest in Viacom was held by independent shareholders, the Redstone family maintained 71-percent voting control of the company through National Amusements' holdings of Viacom's stock.
In 2002, Viacom's MTV Networks International bought independently run Dutch music video channel TMF, which at the time was broadcasting in Belgium and the Netherlands. In June 2004, MTVNI bought VIVA Media AG, the German equivalent to MTV. The same month, plans were announced to dispose of Viacom's interest in Blockbuster later that year by means of an exchange offer; the spinoff of Blockbuster was completed in October.
Also in 2002, Viacom acquired the remaining shares of Infinity Broadcasting radio chain, which resulted in Viacom's return to operating radio stations after it originally exited the broadcast radio business in 1997. In April 2003, Viacom acquired the remaining ownership shares of Comedy Central from then-AOL Time Warner, integrating Comedy Central into MTV Networks.

### Viacom Cable

From its formation until 1995, Viacom operated several cable television systems generally located in the Dayton, San Francisco, Nashville and Seattle metropolitan areas. Several of these were originally independent systems that CBS acquired in the 1960s. The division was known as Viacom Cablevision until the early 1990s, when it was renamed to Viacom Cable. By 1995, Viacom Cable had about 1.1 million subscribers. Viacom sold the division to TCI in 1995. Viacom's cable assets are now part of Comcast.

### Corporate spin-off

In March 2005, Viacom announced that it would split into two companies – one would contain Viacom's "slow-growth" assets; the other would consist of the company's "high-growth" divisions – under National Amusements' control because of a stagnating stock price. The internal rivalry between CBS chairman Les Moonves and MTV Networks chief executive officer Tom Freston, and the controversy of the Super Bowl XXXVIII halftime show were also seen as factors. After the departure of Mel Karmazin in 2004, Redstone, who served as chairman and CEO, decided to split the offices of president and chief operating officer between Moonves and Freston. Redstone was set to retire in the near future, and a split would be a creative solution to the matter of replacing him.
The existing Viacom would become the second CBS Corporation as it was headed by Moonves and kept CBS, Simon & Schuster, and Paramount Network Television (now known as CBS Studios), among other assets; while MTV Networks, BET Networks, and Paramount Pictures would spin-off to a sister company headed by Freston under the Viacom name. The split was approved by Viacom's board on June 14, 2005, and took effect on December 31. The second iterations of CBS Corporation and Viacom began trading on January 3, 2006.
On August 13, 2019, CBS and Viacom officially announced their re-merger deal; the combined company would be called ViacomCBS, with Bob Bakish as president and CEO and Shari Redstone as the chairwoman of the new company. The deal was closed on December 4.
Despite ViacomCBS renaming itself to Paramount Global on February 16, 2022, several Paramount retired the Viacom name by assets for 52 years.

## Viacom International

Viacom International Inc. was established in 1971, just a year after Viacom spun out from the CBS TV network and became Viacom's parent company. The company is responsible for copyrights and trademarks associated with its corporate websites, applications and cable networks, specifically its Media Networks division. The division also licenses the product rights for their various properties and the dissemination of visual and textual television programs on a subscription/fee basis.
Viacom International also served as the licensee name and division for its group of television stations for FCC purposes before the 1995 Westinghouse/CBS merger. Former Viacom station WVIT in New Britain, Connecticut (serving Hartford and New Haven), which it owned from 1978 until 1997, took its call letters from the initials of Viacom International, and retains them to the present day under NBC ownership.
In 2006, Viacom International was renamed to CBS Operations, Inc., and its copyrights related to Viacom's cable networks were transferred to a new Viacom International company and become in name-only unit of Viacom. The new Viacom International company to cease operations and CBS Operations, Inc. folded into CBS after Viacom and CBS merged to create ViacomCBS in 2019 and ViacomCBS rebranded as the current Paramount Global in 2022. ViacomCBS International Inc. was used as an alternate trade name for the new company during the 2020–21 television season.
