In 1926, a subsidiary, Fox Movietone Corporation, was created, tasked with producing newsreels using Fox's recently acquired sound-on-film technology. The first of these newsreels debuted on January 21, 1927. Four months later, the May 25 release of a sound recording of Charles Lindbergh's departure on his transatlantic flight was described by film historian Raymond Fielding as the "first sound news film of consequence". "Movietone News" was launched as a regular newsreel feature December 3 of that year. Production of the series continued after the merger with Twentieth Century Pictures, until 1963, and continued to serve 20th Century Fox after that, as a source for film industry stock footage.
