 In 1947, the United States Justice Department filed an antitrust suit against Technicolor for monopolization of color cinematography (even though rival processes such as Cinecolor and Trucolor were in general use).In 1950, a federal court ordered Technicolor to allot a number of its three-strip cameras for use by independent studios and filmmakers.Although this certainly affected Technicolor, its real undoing was the invention of Eastmancolor that same year.
