The Swoosh is the logo of American sportswear designer and retailer Nike. Today, it has become one of the most recognizable brand logos in the world, and the most valuable, having a worth of $26 billion alone.Bill Bowerman and Phil Knight founded Nike on January 25, 1964, as Blue Ribbon Sports. Upon changing its name to Nike, Inc. on May 30, 1971, the company adopted the Swoosh as its official logo the same year. Carolyn Davidson, a student at Portland State University during the time Knight taught there, created the logo, attempting to convey motion in its design.
