and the Sunbeam Mixmaster became the most popular among consumers until the 1950s. KitchenAid mixers remained popular, and in the late 1930s, the factory would completely sell out its products each Christmas. The factory was closed for the duration of World War II. After the war, production started up again in 1946 when the factory moved to Greenville, Ohio, to expand capacity. The product range expanded beyond stand mixers for the first time in 1949, when dishwashers were introduced. In 1985, the company purchased the Chambers Company to incorporate its range of cookers into the KitchenAid brand. After being cleared by a Federal appeals court in January 1986, Whirlpool Corporation was cleared to purchase KitchenAid for $150 million, after initial complaints regarding competition from dishwasher manufacturers White Consolidated Industries and Magic Chef were dismissed. Refrigerators were added to the product line later in 1986. The company used the popularity of celebrity chefs during the late 1980s to seize the chance to expand its customer range. In 1988, retailer Williams Sonoma was opening new stores across the United States and released a cobalt blue stand mixer for the company. Although the retailer had been carrying KitchenAid products since 1959, the new stores introduced the mixers to a wider range of home cooks. This combined with a change in marketing strategy for KitchenAid, which resulted in a doubling of brand awareness over the course of the following three years. KitchenAid began manufacturing blenders and other small appliances in the mid-1990s. The brand was further promoted by sponsoring the PBS show Home Cooking, and by introducing the mixers to television chefs such as Julia Child and Martha Stewart. Following the success with Williams Sonoma, specific points of purchase were set up in department stores such as Kohl's and Macy's. Specific color mixers were released for specific retailers or to benefit charities, such as a pink mixer released to raise funds for breast cancer research or mixers sold at Target stores being available in that company's signature shade of red. The ProLine range of appliances was launched in 2003 with an initial six-month exclusivity agreement with Williams Sonoma. Design and manufacturing Egmont Arens was hired in the 1930s to design a low-cost series of mixers. This resulted in the production of the KitchenAid Model "K" which featured a streamlined profile for the first time, and the KitchenAid standard design has remained relatively unchanged since
