Searle & Co. was the first on the market with Enovid. In 1960, Frank B. Colton, a research chemist at Searle, had developed Enovid, which contains mestranol and norethynodrel. But by 1964, norethindrone had become the most widely used active ingredient of the Pill. TWO YEARS after Enovid hit the market, 1.2 million American women were using the Pill; in 1965, 5 million; and in 1973, about 10 million.
