Until the 1960s, razor blades were made of carbon steel. These were prone to rusting unless carefully dried and often left users to change blades frequently. In 1965, the British company Wilkinson Sword began to sell blades made of stainless steel, which did not rust and could be used until blunt. Wilkinson quickly captured U.S., British and European markets. As a result, American Safety Razor, Gillette and Schick were driven to produce stainless steel blades to compete. Today, almost all razor blades are stainless steel although carbon steel blades remain in limited production for lower income markets. Because Gillette held a patent on stainless blades but had not acted on it, the company was accused of exploiting customers by forcing them to buy the rust-prone blade.

Editor's Note: Pep was a brand of whole-wheat breakfast cereal produced by the Kellogg Company, and introduced in 1923. Pep was a long-running rival to Wheaties, and also the sponsor of Mutual Radio's The Adventures of Superman radio series. One of Pep's advertising slogans was "the Sunshine cereal".

Pep became one of the first "fortified" cereals, with an infusion of vitamins, beginning in the 1930s. Extensive advertising, from print advertisements to sponsorship of The Adventures of Superman, helped keep the brand in the public's consciousness. Pep was included in "variety packs" of serving-sized boxes of Kellogg's cereals. The cereal's "mildly laxative" property was routinely mentioned in print ads.[1] Despite its pluses, Pep faded from popularity as public tastes changed, and the brand was discontinued in the late 1970s.
