TSR, Inc., originally called Tactical Strategy Rules, Founded in 1973 by Gary Gygax and Dave Arneson when the two were looking for a company to publish their new gaming system, Dungeons & Dragons. Over the years, Tactical Strategy Rules became TSR Hobbies and later TSR, Inc, as the company continued to produce content for the Dungeons & Dragons gaming system.

TSR produced a significant amount of gaming material for Dungeons & Dragons, including campaign worlds like Dragonlance, Forgotten Realms, and Greyhawk. In addition, TSR produced gaming material for other branded properties, such as Buck Rogers, Conan the Barbarian, Indiana Jones, and Marvel Comics, as well as other gaming systems independent of D&D, like Alternity and Gamma World.

TSR also produced non-gaming material as well. TSR produced four magazines over its lifetime, including D&D supplemental magazines Dragon and Dungeon. The company also produced novels, board games, and comic books.

In 1997, TSR was absorbed by Wizards of the Coast, who continued to publish the Dungeons & Dragons gaming material.
