San Francisco is also the location of the notorious Mitchell Brothers O'Farrell Theatre. Originally an X-rated movie theater, this striptease club pioneered lap dancing in 1970, and was a major force in popularizing it in strip clubs on a nationwide and eventually worldwide basis. A further development in the American tradition took place with the emergence of upscale "gentlemen's clubs" in the early 1990s in large cities such as New York. Scores New York was the first major gentlemen's club, with "a gorgeous interior, high-end food and drinks, and of course stunningly beautiful women in sexy gowns. Prior to that, live adult entertainment in New York consisted largely of seedy peep show-type places," according to adult industry veteran Joe Diamond.
