Edmund Goldman and Sam Nathanson established Manson Distributing Corporation in 1953. The company began by importing foreign films for American audiences before incorporating as a formal business entity by 1962.
Manson International shifted its focus toward sex trip movies categorized as either hard or soft content depending on explicitness levels. Notable releases from this period include Blood Feast in 1963, Two Thousand Maniacs! in 1964, Mission Batangas in 1968, Nightmare in Wax in 1969, Santa and the Three Bears in 1970, and Cycles South in 1971.
Edmund Goldman's son Michael took control of the company in 1975 and redirected operations away from sex trip movies toward independent film licensing. This new direction emphasized marketing strategies for international markets rather than domestic exploitation fare while releasing titles like Tourist Trap and Laserblast in 1978.
Management Company Entertainment Group purchased Manson in 1987 through Jonathan D. Krane's production firm. Following the sale, Intercontinental Releasing switched distribution to United Film Distribution Company instead of staying with Manson before Management Company merged with Orion Pictures in 1995.
Manson distributed many films outside North America including Scanners which appeared in 1981 as a science fiction horror film that gained critical attention years later. Brain Damage emerged in 1988 becoming another beloved title among genre enthusiasts alongside other diverse catalog entries like Eddie and the Cruisers in 1983.
