In May, 2004, William Morrow published “My Life Among The Serial Killers,” which Harold Goldberg co-authored with world renowned psychiatrist Dr. Helen Morrison.  In addition to the U.S. editions, the books have recently been published in the U.K., Canada, Japan, France, Germany, Spain, Australia, New Zealand, Russia, and elsewhere.  It was serialized in the Times of London and was a selection of seven book clubs, including the Today Show book club.

In 2007, he began to write for the American Movie Classics Web site, shaping content and interviewing directors and actors for a new generation of viewers of shows like “Mad Men” and “Breaking Bad.” Here, he wrote seven pieces daily about movies and popular culture. He was the first person to write about videogames for AMC. He also improved the site's voice, brought in established writers, developed a payment structure and made certain that movie companies supported the site. In 2008 as a writer, he helped to launch a landmark gaming site called Crispy Gamer, the only one that refused ads from video game companies. Sadly, it imploded in 2010.

As the former editor in chief of Sony Online Entertainment, Harold Goldberg helped to shape the words for dozens of games, including “EverQuest,” one of Time magazine’s best games of 2000.  At Sony, he created “Motherboard,” an online magazine about the culture of games featuring famed writers like Michael Crichton, Nick Tosches and John Saul.  Also contributing were actress Michelle Williams, director Gus Van Sant and animator Bill Plympton.

Goldberg was one of the original videogame reviewers for Wired and Entertainment Weekly and is currently the videogame critic for Boys’ Life.  As a syndicated newspaper columnist for three years, Goldberg penned a weekly column called “Gameplay of the Week.”

James Ledbetter, editor in charge at Reuters.com and now EIC of Inc., says the book is "a story that is as riveting and addictive as the games (Goldberg) writes about." Matt Helguson, senior editor of Game Informer, says "if you're one of the millions of people who have fallen in love with videogames, this is required reading." And Ken Levine, creative director at Irrational Games, the makers of BioShock, says "Harold Goldberg's portrait of a weird, often dysfunctional and amazing videogame industry makes a great, great read."

In October, 2011, Goldberg joined forces with Emmy Award winner musician Anton Sanko, twice-Oscar-nominated animator Bill Plympton and Steven Spielberg/Sam Raimi storyboard artist Dave Lowery. Together, they created the online movie event, Playing With Fire.
