Metro-Goldwyn-Mayer Studios, Inc. (abbreviated MGM or M-G-M, also known as Metro-Goldwyn-Mayer Pictures, Metro-Goldwyn-Mayer, or simply Metro) is an American media company, involved primarily in the production and distribution of feature films and television programs. It was the current parent of United Artists. In 1986, Ted Turner's Turner Broadcasting System acquired MGM from Kirk Kerkorian; due to concerns over the debt load of his companies, that same year, Turner was forced to sell MGM back to Kerkorian after approximately only 74 days of ownership. However, Turner kept much of MGM's film and television library made prior to May 1986, that includes MGM cartoons, as well as some of the United Artists library, and formed Turner Entertainment Co. However, some of WB's old monogram films remain with MGM.
