When The Sun became a tabloid on 17 November 1969, it began intermittently publishing images of clothed glamour models on its third page. The editors introduced nudity on 17 November 1970 when they printed an image of 22-year-old model Stephanie Khan in her "birthday suit" to celebrate the newspaper's first anniversary as a tabloid. Topless Page 3 girls soon became a regular feature in The Sun and are credited with helping to boost the newspaper's circulation significantly in the 1970s and 1980s. Some Page 3 girls became household names. Samantha Fox, who appeared on Page 3 from 1983 to 1986, became one of the most photographed British women of the 1980s, and famously earned more than then-prime minister Margaret Thatcher while still in her teens. Britain's other "red top" tabloids introduced competing features under different names. The Daily Star called its topless models "Starbirds. " The Daily Mirror also experimented with topless models, although it scrapped the feature in the 1980s.
