pandering to them, saying "We don't want it to become known as a nigger drink." After Mack left the company in 1950, support for the black sales team faded and it was cut. Boyd was replaced in 1952 by Harvey C. Russell Jr., who was notable for his marketing campaigns towards black youth in New Orleans. These campaigns, held at locales attended largely by black children, would encourage children to collect Pepsi bottle caps, which they could then exchange for rewards. One example is Pepsi's 1954 "Pepsi Day at the Beach" event, where New Orleans children could ride rides at an amusement park in exchange for Pepsi bottle caps. By the end of the event, 125,000 bottle caps been collected. According to The Pepsi Cola World, the New Orleans campaign was a success; once people's supply of bottle caps ran out, the only way they could get more was to buy more Pepsi. Rivalry with Coca-Cola According to Consumer Reports, in the 1970s, the rivalry continued to heat up the market. Pepsi conducted blind taste tests in stores, in what was called the "Pepsi Challenge". These tests suggested that more consumers preferred the taste of Pepsi to Coca-Cola. The sales of Pepsi started to climb, and Pepsi kicked off the "Challenge" across the nation. This became known as the "cola wars". In 1985, The Coca-Cola Company, amid much publicity, changed its formula. The theory has been advanced that New Coke, as the reformulated drink came to be known, was invented specifically in response to the Pepsi Challenge. However, a consumer backlash led to Coca-Cola quickly reintroducing the original formula as "Coca-Cola Classic". In 1989, Billy Joel mentioned the rivalry between the two companies in the song "We Didn't Start the Fire". The line "Rock & Roller Cola Wars" refers to Pepsi and Coke's usage of various musicians in advertising campaigns. Coke used Paula Abdul, while Pepsi used Michael Jackson. Both companies then competed to get other musicians to advertise its beverages. According to Beverage Digests 2008 report on carbonated soft drinks, PepsiCo's U.S. market share is 30.8 percent, while The Coca-Cola Company's is 42.7 percent. Coca-Cola outsells Pepsi in most parts of the U.S., notable exceptions being central Appalachia, North Dakota, and Utah. In the city of Buffalo, New York, Pepsi outsells Coca-Cola by a two-to-one margin. Overall, Coca-Cola continues to outsell Pepsi in almost all areas of the world.
