The "Swoosh" logo is recognized around the worlds. It is the symbol of the athletic shoe and clothing manufacturer Nike. Nike Swoosh was designed by Carolyn Davidson and it used by Nike, Inc. Carolyn Davidson is a graphic design student at Portland State University. She met Phil Knight while he was teaching accounting classes and she started doing some freelance work for his company, Blue Ribbon Sports (BRS).
BRS imported Onitsuka Tiger brand running shoes after seven years of its founding in 1964. Also BRS decided to create its own brand- Nike. In the spring of 1971, Davidson presented a number of design options to Knight and other BRS executives, and they ultimately selected the mark now known globally as the Swoosh. "I don't love it, but I think it will grow on me." Davidson submitted a bill for US$35 for her work. In 1983, Knight gave Davidson a diamond Swoosh ring and an envelope filled with Nike stock to express his gratitude.
In June 1972, the first running shoes bearing the Swoosh were introduced at the U.S. Track and Field Olympic Trials in Eugene, Oregon. Nike continues to use the brand today.
