Viacom Enterprises was the television distribution division of the CBS Television Network, formed in 1952 as CBS Television Film Sales, later renamed to CBS Films in 1958, CBS Enterprises, Inc. in 1968, then to Viacom in 1970. In 1971, it was spunoff to comply with FCC regulations prohibiting television networks from distributing their programs under their own names. Subsequently, Viacom formed "Viacom Productions" to produce firstrun television series airing on the major television networks.

The company was popular during the 1970s and 1980s, originally distributing CBSproduced shows such as I Love Lucy and The Andy Griffith Show. In later years, they've distributed shows from numerous other production companies, including MTM Enterprises, Filmways Television, Carsey/Werner, Lorimar Television, Rankin/Bass, and HannaBarbera (the latter mostly internationally). They also distributed several Four Star shows, and early Nelvana TV specials, as well as most movie releases from Romulus Films, Hallmark Hall of Fame, Tomorrow Entertainment, New World Pictures (until 1984), Orion Pictures, New Line Cinema, Cannon Films, and the Terrytoons library, among others, until they formed their own syndication companies. In 1971, Viacom and its production division formed "Viacom International, Inc." as their new parent company for distributing programs overseas.

Within a decade, Viacom was bought by cinema chain National Amusements, becoming part of the newlyreincorporated "Viacom, Inc." On January 1, 1990, as part of a restructuring, Viacom Pictures was formed. On March 11, 1994, Viacom acquired Paramount Communications, Inc. and Viacom Enterprises was folded into Paramount Domestic Television (later "CBS Television Distribution" and now "CBS Media Ventures"), by transferring the domestic rights of the Viacom library. Viacom International was later reorganized as the parent company of MTV Networks and Showtime Networks. Viacom transferred the international rights of the said library into Paramount International Television, while Viacom Productions was reincorporated as a production subdivision of Paramount Television. The Viacom Enterprises logo of the era was still used for "Viacom Productions" with an updated variant, and would remain until 1999, receiving another update to the logo to reflect the company's new status after merging with former parent company CBS. The 19992004 Viacom logo would be its last, as the final two series to end under the Viacom Productions name would be Ed and The Division.

In light of serious financial troubles brought on to Viacom, the production unit was folded into Paramount Network Television (now "CBS Studios") in 2004. Paramount took control of the remaining Viacomproduced series in 2005. On December 31 of that year, Viacom was reincorporated as "CBS Corporation", ceasing to exist officially. A "new" Viacom was established on the same day, as the holding company for Paramount Pictures, the MTV Networks, BET Networks, and their nontelevision firms. By 2009, most Viacomdistributed TV productions were distributed under CBS Media Ventures (formerly "CBS Paramount Domestic Television" and "CBS Television Distribution") and outside the U.S. under Paramount Global Content Distribution (formerly "CBS Paramount International Television" and "CBS Studios International"), while the previous Viacomdistributed movies, and some Viacom Domestic Media Networks TV shows were distributed by Paramount with U.S. overtheair rights licensed to Trifecta Entertainment and Media. On December 4, 2019, Viacom and CBS remerged, forming ViacomCBS. On February 16, 2022, ViacomCBS was renamed to Paramount Global, putting the Viacom name to rest after 51 years.

Before the Paramount purchase, Viacom titles were distributed on home video by Magnetic Video Corporation, CBS Video Enterprises (coincidental as Viacom would later own CBS), Warner Home Video, VidAmerica, Forum Home Video and U.S.A. Home Video, among others. A little known fact is that Viacom actually stands for "Visual Audio Communications".
