In 1970, the contest in London was disrupted by women’s liberation protesters armed with flour bombs, stink bombs, and water pistols loaded with ink. The 1970 contest was also controversial when South Africa sent two contestants (one black and one white). Henceforth, South Africa was banned from the contest until apartheid was abolished. More than 18 million people watched the pageant at its peak during the late 1970s and early 1980s.
