When was 20th century fox made?

20th Century Fox was founded in 1935. It was formed through the merger of two companies:

* Fox Film Corporation, founded in 1915 by William Fox

* Twentieth Century Pictures, founded in 1933 by Joseph Schenck and Darryl F. Zanuck

While the name "20th Century Fox" suggests a foundation at the beginning of the 20th century, the actual merger and the official naming of the studio took place in 1935.
