kept MGM's pre-May 1986 and pre-merger film and television library. Turner Entertainment was established in August 1986 to oversee film and television properties owned by Turner thanks to the deal with Kerkorian. Having now acquired MGM's library of 2,200 films made before 1986, Turner had them syndicated on his nationwide television stations. When broadcasting their older films, he aired colorized versions of ones originally shot in black-and-white. Opposition arose from cinephiles, actors, and directors to Turner's colorization efforts. Film critic Roger Ebert wrote on Turner's broadcasting of a colorized Casablanca, "that will be one of the saddest days in the history of the movies. It is sad because it demonstrates that there is no movie that Turner will spare, no classic however great that is safe from the vulgarity of his computerized graffiti gangs." Thanks in part to Turner's colorization, the Library of Congress established the National Film Registry with the aim to preserve American films in their original format. In 1988, Turner purchased Jim Crockett Promotions which he renamed World Championship Wrestling (WCW) which became the main competitor to Vince McMahon's World Wrestling Federation (WWF). This rivalry became known as the Monday Night Wars, and would last throughout the 1990s. In 2001, under AOL Time Warner, WCW was sold to the WWF. Also in 1988, he introduced Turner Network Television (TNT) with Gone with the Wind. TNT, initially showing older movies and television shows, added original programs and newer reruns. Turner would later create Turner Classic Movies (TCM) in 1994, airing Turner's pre-1986 MGM library of films alongside those of Warner Bros. made before 1950, though it has expanded its library since. In 1989, Turner created the Turner Tomorrow Fellowship for fiction offering positive solutions to global problems. The winner, from 2500 entries worldwide, was Daniel Quinn's Ishmael. In 1990, he created the Turner Foundation, which focuses on philanthropic grants concerning issues pertaining to the environment and overpopulation. In the same year he created Captain Planet, an environmental superhero. Turner produced the television series Captain Planet and the Planeteers and its later sequel series with Captain Planet as the featured character. In 1992, the pre-May 1986 MGM library, which also included Warner Bros. properties including the early Looney Tunes and Merrie Melodies libraries and also the Fleischer Studios and Famous Studios Popeye cartoons from Paramount (and then United Artists), became the core of Cartoon Network.
