High Quality Content by WIKIPEDIA articles! Official U.S. PlayStation Magazine (often abbreviated to OPM) is a now-defunct monthly video game magazine, published by Ziff Davis Media. It was a sister publication of Electronic Gaming Monthly. The magazine focused exclusively on PlayStation hardware, software, and culture, covering the original PlayStation, PlayStation 2, PlayStation 3, and PlayStation Portable. Perhaps the most famous aspect of the magazine was the inclusion each month of a disc that contained playable demos and videos of PlayStation games. The magazine was produced for nearly ten years, from September 1997 to the final issue in January 2007.
