 Now that being a pornographer was a legitimate occupation, there was no shortage of businessmen to invest in proper plant and equipment capable of turning out a mass-produced, cheap, but quality product.Vast amounts of this new pornography, both magazines and films, were smuggled into other parts of Europe, where it was sold "under the counter" or (sometimes) shown in "members only" cinema clubs.The first explicitly pornographic film with a plot that received a general theatrical release in the U.S. is generally considered to be "Mona the Virgin Nymph" (also known as "Mona"), a 59-minute 1970 feature by Bill Osco and Howard Ziehm, who went on to create the relatively high-budget hardcore/softcore (depending on the release) cult film "Flesh Gordon".
