Turner Broadcasting System
In 1991, Turner Broadcasting System acquired animation studio Hanna-Barbera and the Ruby-Spears library from Great American Broadcasting, and years later, Turner Broadcasting System acquired Castle Rock Entertainment on December 22, 1993, and New Line Cinema on January 28, 1994. On October 10, 1996, Time Warner acquired Turner Broadcasting System, thus bringing Warner Bros.' pre-1950 library back home. However, Warner Bros. only owns Castle Rock Entertainment's post-1994 library.
