In March 1981, Columbia Pictures established a joint venture with RCA, RCA/Columbia Pictures International Video, to distribute tapes in overseas markets. The partnership expanded to North America as RCA/Columbia Pictures Home Video the following year. The venture distributed NBC titles, as it was a subsidiary of RCA at the time. When Tri-Star Pictures was formed in 1984, R/CPHV became one of the three primary distributors of Tri-Star product for home video (the other two being CBS/Fox Video and Thorn-EMI/HBO Video {later renamed to HBO/Cannon Video and then simply HBO Video}, as CBS and HBO originally held stakes in Tri-Star), and fully assumed distribution of TriStar titles in the early 1990s. They also distributed titles from various other film companies unrelated to Columbia, including most of New Line Cinema's theatrical releases (though not all, as Media Home Entertainment and Family Home Entertainment distributed several New Line films during the Columbia deal). New Line formed their own video label in 1990 (the result of acquiring Nelson Entertainment, which had previously been Embassy Home Entertainment, ironic considering Embassy had been owned by Columbia for a brief period of time before being spun off), but continued to go through RCA/Columbia Pictures (as well as SVS-Triumph and then Columbia TriStar Home Video) for distribution until 1994, when Turner Broadcasting acquired New Line and Turner Home Entertainment assumed distribution functions.
