In what year did William Fox found Fox Film Corporation, later known as 20th Century Fox?

The Fox Film Corporation was an American company that produced motion pictures, formed by William Fox on 1 February 1915. It was the corporate successor to his earlier Greater New York Film Rental Company and Box Office Attractions Film Company.

The company's first film studios were set up in Fort Lee, New Jersey but in 1917, William Fox sent Sol M. Wurtzel to Hollywood, California to oversee the studio's new West Coast production facilities where a more hospitable and cost effective climate existed for filmmaking. On July 23, 1926, the company bought the patents of the Movietone sound system for recording sound on to film.

After the Crash of 1929, William Fox lost control of the company in 1930, during a hostile takeover. Under new president Sidney Kent, the new owners merged the company with Twentieth Century Pictures to form 20th Century Fox in 1935.
