Dragon was one of the two official magazines for source material for the Dungeons & Dragons role-playing game and associated products. TSR, Inc. originally launched the monthly printed magazine in 1976 to succeed the company's earlier publication, The Strategic Review. In 2002, Paizo Publishing acquired the rights to publish both Dragon and its companion periodical Dungeon under license from Wizards of the Coast. It tied Dragon more closely to Dungeon by including articles supporting and promoting its major multi-issue adventures such as the Age of Worms and Savage Tide. Class Acts, monthly one or two-page articles offering ideas for developing specific character classes, were also introduced by Paizo. The final printed issue was #359 in September 2007. Shortly after the last issue shipped in mid-August, 2007, Wizards of the Coast, the publication's current intellectual property rightsholder, re-launched Dragon as an online service at its website.
