Diabolic Video Productions is an American independent porn studio founded in 1998 by Gregg Allan and Christopher Alexander, and currently owned by Zero Tolerance Entertainment. The company was a pioneer of gonzo pornography, and one of the most successful gonzo producers. Diabolic originally worked as a sister studio for Anabolic Video, and both companies were in Venice, California for 10 years. They moved to Chatsworth in 2001 and announced in May 2007 that they would terminate their partnership and operate as separate companies. Diabolic has since been owned and controlled by Gregg Allan. The studio produced more than 280 films by 2007. In April 2008, their first Blue-ray title, "Top Shelf," was released with stars like Amy Ried, Courtney Cummz, Jenna Haze and Sarah Vandella. The company started shooting in HDs years ago. Diabolic.com's premium porn site offers wide spectrum content, including anal sex, gangbangs, orgies, creampies, family roles, teenage and MILF categories. The site has more than 23 years of experience in the porn industry. The 3-day trial period between subscription options is limited to $2.95 and monthly packages are between $19.95 and $29.95 with unlimited streaming and download options. The annual package is $9.95 a month with a monthly salary of $119.40. In the history of Diabolic, it was a major event that FBI agents visited their offices in 2006 based on the Child Protection and Obscensity Development Act to check the records of 23 films and their performers - this was the first such investigation since 1988. Diabolic successfully passed the check.
