Celebrity endorsements played a significant role in the pants' acceptance as casual wear. James Dean in 1955 Rebel Without a Cause, Marlon Brando in 1953 The Wild One, and Marilyn Monroe in 1961 The Misfits served as symbols of the counterculture that baby boomers embraced, as well as their choice in denim. Levi Strauss and Co. had initially patented the blue trousers, but emerging brands quickly followed suit. Sturdy work attire was manufactured by early competitors: Carhartt, founded 1889, Lee, founded 1889, and Wrangler, founded 1947. Despite the diversity in style and production, jeans have consistently been a symbol of independence.
