the US adult-film industry, at $3.5-4 billion in annual sales, rentals, cable charges, and video-masturbation-booth revenues, is an even larger and more efficient moneymaking machine than legitimate mainstream American cinema (the latter's annual gross commonly estimated at $2-2.5 billion). The US adult industry is centered in LA's San Fernando Valley, just over the mountains from Hollywood. Some insiders like to refer to the adult industry as Hollywood's Evil Twin, others as the mainstream's Big Red Son. (из NY Times)
