In the postwar period, there were other developments that fostered the emergence of a mass market. The introduction of the 8-mm film and Super 8 format provided for a wide spread of amateur filmmaking. Entrepreneurs discovered that market for itself. In Great Britain were the productions of Harrison Marks soft porn, but were classified in the 1950s as slippery. On the continent, such films were explicit. Lasse Braun was a pioneer in color quality productions, which he sold in the early days with the help of his father's diplomatic privileges. In 1969, the pornography was legalized in the Netherlands, which led to an explosion of commercially produced pornography. As the porn producer now pursued a legitimate employment, there were no restrictions for businessmen to invest in proper equipment with which they were able to deliver quality products in bulk and cheap to manufacture. Large quantities of these new pornography, both magazines and films were smuggled to other parts of Europe where they are "under the counter" or sold in movie theaters showed only accessible for members.
