Ken Albert, Warren Stephens, Robert Walters, and Scott Masters were all pseudonyms of the same anonymous erotic film producer and director. In the mid 1960s he sold unreleased still gay male erotic images from well-known studios in photosets and later compiled the images into magazines. Masters soon found it profitable to shoot and sell his own works including films, photographs, and slides. In the early 1970s he opened the Stephens Agency to distribute his works, but soon found the business of distribution unprofitable. Ironically, Masters was arrested for distributing erotic images through U.S. mail in Texas after closing the Stephens Agency. The case was transferred to Los Angeles and Masters was placed on probation; nevertheless, he continued to produce films. He went on to open Nova Studios as Robert Walters. After closing Nova Studios, he took the name Scott Masters. In 1987 Masters was hired by Catalina Video where he rose to the position of head of production. After leaving Catalina Video in 1992, he co-founded Studio 2000 with director John Travis. In 2006, Studio 2000 was sold to David McKay.
