The country now houses over 40 adult movies studios featuring heterosexual scenes, more than any other country. The branch, according to founder and president of "Adult Video News" Paul Fishbein, involves the manufacturers of adult products, distributors, suppliers, retail store owners, wholesalers, distributors, cable TV buyers, and foreign buyers. The production is concentrated in San Fernando Valley (mainly in Chatsworth, Reseda and Van Nuys) and Las Vegas, where more than 200 adult entertainment companies gather to network and show off their latest wares. The world's largest adult movies studio, Vivid Entertainment, generates an estimated $100 million a year in revenue, distributing 60 films annually and selling them in video stores, hotel rooms, on cable systems, and on the Internet. Vivid's two largest regional competitors are Wicked Pictures and Digital Playground. Colorado-based New Frontier Media, a leading distributor of adult movies (at NASDAQ since November 2000), is one of the two adult video companies traded publicly, the other one being Spanish Private Media Group.
