On April 2, 1993 Philip Morris USA launched an elaborate integrated program of consumer and retail promotions of unspecified duration that effectively slashed the retail price of its flagship brand, Marlboro, by 20% in the U.S. market. This program represented a major shift in strategy designed by Philip Morris to reverse the alarming declines in Marlboro's market share, which had occurred in the face of severe price competition from discount brands. Given Marlboro's status as one of the world's premier brands and the changing environment of consumer marketing, the date these actions were announced was immediately labeled "Marlboro Friday" and heralded as a milestone in marketing history.
