The start of the circuit has been attributed to many different parties that sprang up during the time-frame of the late 1970s and early 1980s. These proto-circuit parties in the late 1970s, the precursors of what later became circuit parties, were called "disco parties." They lasted one evening only, and were held in various large venues in metropolitan areas with large gay populations. Although Flamingo and 12 West were New York clubs that had theme-centered gay parties, these nightclubs were eclipsed by the opening of the mega-nightclub, The Saint, in the East Village in 1980. This members-only male (with very limited exceptions) club was very technologically advanced. Some say its like has not been recreated since.
