The "golden ages" of some entertainment genres are hard to define. But many connoisseurs of sex films define that form's peak as the 1970-87 era of theatrical porno; after "stag films" emerged from the underground into real theaters, but before home video and zoning restrictions across the country put many of the theaters out of business. After '87, when the last on-film theatrical porno was released, most remaining adult cinemas switched to video-projection systems. The Apple Theater was one of the last film-based porno houses in the U.S. when it was razed in 1998, to make way for an affordable-housing project. The new building's storefront tenant is involved in a different "skin trade"--tattoos.
