Established in the 1940s in Sweden by Ingvar Kamprad, IKEA has grown rapidly in recent years to become one of the world's largest retailers of home furnishings. In its initial push to expand globally, IKEA largely ignored the retailing rule that international success involves tailoring product lines closely to national tastes and preferences. Instead, IKEA stuck with the vision, articulated by founder Kamprad, that the company should sell a basic product range that is "typically Swedish" wherever it ventures in the world. The company also remained primarily production oriented; that is, the Swedish management and design group decided what it was going to sell and then presented it to the worldwide public—often with little research as to what the public wanted. The company also emphasized its Swedish roots in its international advertising, even insisting on a "Swedish" blue and gold color scheme for its stores.
