Lever Brothers, the makers of Rinso, Lifebuoy, and Lux soap, revised its advertising copy over the years to reflect the changing cultural meanings of soap itself... In 1916, Lux was "a wonderful new product" for "laundering fine fabrics:; by the mid-twenties it could also preserve "soft, youthful, lovely feminine hands" and, by the early thirties, prevent "undie odor" as well—"She never omits her Daily Bath, yet she wears underthings a SECOND DAY."

Francis Countway, the president of Lever Brothers and the individual most responsible for the "discovery" of body odors and the "stop smelling" ad pitch, was inspired by Listerine's successful advertising campaign against the previously unknown halitosis. Countway and his associates admitted, while Lever Brothers' business boomed, that they cared little "about the opinions of softies who think that the Body and Undie Odor copy is disgusting." They were simply doing their job, "bringing cleanliness into a dirty world."

When the Bic brand applied its name to women's underwear, consisting of a line of 'disposable pantyhose', they were unable to attract customers. Okay, so the disposability element was still there. But that was about it. Consumers were unable to see any link between Bic's other products and underwear, because of course there was no link.

The main problem was that the company insisted on using the Bic name. As marketing writer Al Ries has observed, using the same name in unrelated categories can create difficulties. "If you have a powerful perception for one class of product, it becomes almost impossible to extend that perception to a different class," he argues.
