Diabolic Video Productions is an American pornographic movie studio headquartered in Chatsworth, California owned by Zero Tolerance Entertainment. The company was originally a sister-studio of Anabolic Video. During their partnership the studios were a pioneer of gonzo pornography, and are considered one of the most successful gonzo producers. History Anabolic and Diabolic were originally headquartered in Venice, California for 10 years. Diabolic was founded as a separate label in 1998 by Gregg Allan, and Anabolic Video head Christopher Alexander. Alan had previously run the two companies sales department for 15 years, starting in 1992. On January 15, 1998, Diabolic Video released its first video. In 2001 Anabolic and Diabolic moved their headquarters to Chatsworth. Vouyer's exit to form Red Light District Video in 2002 eventually led to the mass exodus of 2004, which saw Everhard, Steele and Mike John leave for Red Light, and Dough leave for Devil's Film, where the directors were able to own their own movies. In May 2007 Anabolic and Diabolic announced they were ending their partnership, and would operate as separate companies. Diabolic would be run and owned by Gregg Alan, who left his post as head of sales at Anabolic. Diabolic Video updated their DVD packaging with a hologram of the Diabolic logo to help establish themselves as a separate brand from Anabolic. They now feature new videos shot in high definition, best-of collections and Blu-ray. By 2007 the company had produced more than 280 films. In April 2008 Diabolic released its first Blu-ray title, Top Shelf, starring Amy Ried, Courtney Cummz, Jenna Haze, Sarah Vandella, Brianna Love, Audrey Bitoni and Shawna Lenee. It had begun filming in high-definition several years earlier. Directors Anabolic and Diabolic originally used to share directors, but with the split that arrangement ended. Current and former Diabolic directors include Sid Knox. In 2007 Melissa Lauren became the studio's first female director, and directed a volume of the Unnatural Sex series. The same year Ricky D resigned from Diabolic to sign a multi-year exclusive contract with Anabolic. He had directed several film series for Diabolic, including Incumming, 2 on 1, Ass For Days and Hot Sauce.
