Merv Adelson is the co-founder of Lorimar Television with partner Irwin Molasky and Lee Rich in 1969 and was an American television production company that was later a subsidiary of Warner Bros.
Lorimar initially started producing made-for-TV movies for the ABC Movie of the Week. The Homecoming: A Christmas Story, airing during the 1971 holiday season, was a ratings success, and served as the pilot for Lorimar's first major hit production, The Waltons, premiering in 1972. Throughout the 1970s, Lorimar produced several other shows as well, including Eight is Enough; of these, the most popular by far was Dallas. In 1980, Lorimar purchased the bankrupt Allied Artists Pictures Corporation. In the 1980s, Lorimar's output swung toward family-friendly sitcoms; among these were Perfect Strangers and Full House, which were produced by Miller-Boyett Productions.In 1986, Lorimar merged with television syndication firm Telepictures, becoming Lorimar-Telepictures; later that year, they purchased the MGM lot from Ted Turner.
In 1988, Lorimar-Telepictures' production arm became Lorimar Television. In 1989, Lorimar was purchased by Warner Communications, which was merging with Time Inc. to form Time Warner, one of the world's largest media companies. Lorimar's distribution business was folded into Warner Bros. Television Distribution and became Warner Bros. Domestic Television Distribution.The former MGM studio lot was sold to Sony to house Columbia Pictures, TriStar Pictures and Sony's other film operations in which was later named Columbia Studios and is now Sony Pictures Studios. Lorimar continued as a production company until July 1993, when it was folded into Warner Bros. Television, for "economic issues" as a result of declining syndication sales. The last two series to premiere under the Lorimar name were Time Trax and Babylon 5, as part of the 'Prime Time Entertainment Network' programming block. Les Moonves (current president of CBS Corporation) was the president and CEO of Lorimar Television from 1987-1993. Moonves would then become the chairman of Warner Bros. Television after the merger with Lorimar.
Additionally, Lorimar has owned key components of the film library of the defunct Allied Artists film studio (originally Monogram Pictures), which includes Cabaret and Papillon; which are now owned by Warner.Lorimar not only specialized in producing television programs, they also produced a number of theatrical motion pictures, most of which were originally distributed by other studios as noted. In 1985, they had a film production unit known as Lorimar Motion Pictures. In January 1987, the film unit was renamed Lorimar Film Entertainment to coincide with its newly formed in-house distribution unit. In 1988, Lorimar made a distribution deal with Warner Bros. Under Warner, Lorimar continued to make theatrical films until 1990. In 1984, Lorimar purchased Karl Video Corporation (KVC), and was later folded into Warner Home Video.
In Australia, Lorimar joined a venture with Village Roadshow Limited to create Roadshow Lorimar Home Video, which distributed movie titles by Lorimar Motion Pictures in that country.
