In 1996, Turner Broadcasting System merged with Time Warner, which besides placing Turner Classic Movies and Warner Bros. Entertainment under the same corporate umbrella, also gave TCM access to Warner Bros.' library of films released after 1949 (which itself includes other acquired entities such as the Lorimar, Saul Zaentz and National General Pictures libraries); incidentally, TCM had already been running select Warner Bros. film titles through a licensing agreement with the studio that was signed prior to the launch of the channel. In March 1999, MGM paid Warner Bros. and gave up the home video rights to the MGM/UA films owned by Turner to Warner Home Video.
When did MGM give Warner Home Video the rights to Turner Broadcasting's films on home video?
