Though Universal's movie unit did produce occasional movies, among them "Airport", "The Sting", "American Graffiti", and a movie that restored the company's fortunes, "Jaws", Universal in the 1970s was primarily a television studio. Weekly series production was the workhorse of the company. There would be other movies like "", "Back to the Future", and "Jurassic Park", but overall the movie business was still hit-and-miss. In the early 1970s, Universal teamed up with Paramount Pictures to form Cinema International Corporation, which distributed movies by Paramount and Universal worldwide. It was replaced by United International Pictures in 1991, when Walt Disney Pictures joined the fold.
