Pepsi Steps on Coke

According to Consumer Reports, in the 1970s, the rivalry [between Pepsi and Coca-Cola] 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 (which is believed to have more lemon oil, less orange oil, and uses vanillin rather than vanilla) to Coke. The sales of Pepsi started to climb, and Pepsi kicked off the “Challenge” across the [United States].
