20th Century Fox was formed in 1935 through the merger of Fox Film Corporation and Twentieth Century Pictures, founded in 1933. It produced many well-known films and television shows over the decades and was part of the "Big Five" major film studios in Hollywood. Universal Studios was founded in the early 20th century and focused on film production in Hollywood, opening Universal City Studios in 1915. It produced many melodramas, westerns and serials but also had financial troubles with some productions. Both studios have long histories in the film industry.
