KitchenAid is a home appliance brand owned by Whirlpool Corporation. The company was started in 1919 by The Hobart Corporation to produce stand mixers; the "H-5" was the first model introduced. The company faced stiff competition as rivals moved into this emerging market, and introduced its trademarked silhouette in the 1930s with the model "K", the work of designer Egmont Arens. The brand's stand mixers have changed little in design since, and attachments from the model "K" onwards are compatible with the modern machines. Dishwashers were the second product line to be introduced, in 1949. It was in the late '80s with a promotional campaign on the back of an expansion by retailer Williams-Sonoma that saw brand awareness double in three years.
