Way back in 1964, when the editors at SPORTS ILLUSTRATED first dreamed up a swimsuit issue, they were merely trying to keep their readers warm in the midst of yet another cold and boring February. Little did they know that they were launching a national insitution. That first issue had two models and devoted six pages to swimsuits; 37 years later, the SI swimsuit issue is seen-devoured, studied, savored-by more than 60 million people worldwide.
