"This all started in 1998 when I was running Jenna Jameson's fan club, " King told XBIZ. "She got thousands of letters, and half were from people who wanted to get into the business. That was the No. 1 question people asked, and it still is the No. 1 question I'm asked.
"There isn't a comprehensive guide by someone in this industry about the nuts and bolts of how to get into this industry and how to be a success. I decided to sit at the computer — for a few years — and bang it out."
King, who is now vice president of special projects at Wicked Pictures, is widely credited with establishing Jenna Jameson as an adult star after Jameson signed with Wicked as a contract performer in 1995.
The book is self-published.
"I sent book proposals for years to literary agents and publishers, and I couldn't find anybody interested," King said. "Too controversial. So I did it myself."
The book can be ordered through King's website GetIntoPorn.com, and plans call for King to continue offering new information to subscribers.
"Besides the book, I want to give people the tools to get into the business, or be successful once they are in the business," King said. "Provide them with additional assistance. I'm going to have a VIP program, and offer interviews with Lisa Ann, Ron Jeremy and other people in the industry that they can learn from."
