Calvin Klein changed the American market of men's underwear when head of menswear design, John Varvatos, pioneered a hybrid of boxer shorts and briefs famously named boxer briefs, which in 1992 would be publicised by a series of print ads featuring Mark "Marky Mark" Wahlberg. Since then the brand has been called "one of the greatest apparel revolutions of the century."
