Simulations Publications, Inc., was formed in 1969 by James F. Dunnigan, as an entity to oversee the publication of Strategy & Tactics, which Dunnigan purchased from Chris Wagner for the price of one dollar. Dunnigan and SPI quickly became established as more than just a magazine, however, and began producing wargames for both separate sale as well as the revolutionary step of including them in the magazine for subscribers. SPI aggressively entered a market dominated to that point in time by The Avalon Hill Game Company and adopted many other business concepts and practices in addition to its ambitious production schedule. SPI embarked on expensive advertising campaigns, for example purchasing full-page ads in Scientific American, and producing give-away copies of wargames for subscribers and visitors to trade shows (Napoleon at Waterloo went out to subscribers to S&T, while Strike Force One was produced specifically as an introductory game). S&T quickly acquired a much larger subscriber base than The General, though it was admitted that the magazine ran at a financial loss, though it was able to claim the cost of the wargames it produced as advertising costs.
