On August 4, 1986, Ted Turner's Turner Broadcasting System acquired Metro-Goldwyn-Mayer/United Artists from Kirk Kerkorian; due to concerns over the debt load of his companies, on October 17, 1986, 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 (as well as some of the United Artists library) and formed Turner Entertainment.
