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.
