Not too long ago, a Chicago brewery (酿造厂) introduced a new beer that was supposed to be the least fattening(making people fat) on the market. It was lighter, so they called it LITE. Only two months after the new beer had been on sale, however, strange new ads appeared in the Chicago newspapers. They read ’LITE Tastes Soapy’. The public, of course, was confused. Who wanted a beer that tasted like soap(肥皂), even if it was non-fattening?   

The new ads weren’t talking about LITE beer, however. They were for a product of the LITE Soap Company. The president of the LITE Soap Company, Mrs Ruth Ascott, was very upset with the brewery for taking the name of her high-powered detergent (洗涤剂) and using it as the name of a new beer. LITE Soap had had the same name for 53 years. She wrote to the brewery, insisting that they should not use the word LITE in their beer ads. The brewery replied that they could—and would—because beer and soap were so different. They planned to ignore the ’LITE Tastes Soapy’ ads, since the public knew which LITE was which.

Mrs Ascott then wanted to plan a new campaign. The ads would read ’LITE Is Wonderful for Washing Clothes’.
