[Professor]
    Anyone know Nike? I think all of you know it. Now, let’s tall about the history of Nike Company. With billions of dollars in annual sales and a logo recognized the world over, Nike reigns supreme in the athletic footwear and sports clothing market. It all began when Nike co-founders Bill Bowerman and Phil Knight met at the University of Oregon in 1957. Knight was a middle-distance runner and Bowerman was his track coach.
    In 1964, shortly after Knight had earned his MBA, the two went into business together selling Japanese-made running shoes. Soon after, Bowerman began creating prototypes for athletic shoes based on his own designs. In 1967, he introduced a running shoe that was lightweight, yet durable.
    In 1971, the company’s name became "Nike," and their trademark logo became the "Swoosh." The revolutionary Waffle outsole appeared the following year. Nile’s business went from good to better as more of the world’s athletes began wearing Nike’s Waffle-soled footwear. Like the many athletes it supplied shoes to, Nike was a rising star.
    Throughout the 1970s and early ’80s, many runners, football players, and tennis players were competing-and winning-in Nike shoes. Despite the publicity, it was not until Michael Jordan entered the picture that Nike became a household name.
    While still a rookie for the NBA’s Chicago Bulls, Jordan began endorsing Nike’s line of Air Jordan shoes. For the next 15 years, Jordan dazzled sports fans around the globe, all the while wearing Air Jordans. In 1989, Nike’s net income reached US$167 million. Bowerman and Knight had hit the big time.
    Although most people associate the word "Nike’with sports shoes, the name was borrowedfrom a Greek goddess. The ancient Greeks often said, "when we go to battle and win, we say it is Nike!" The Swoosh on every Nike product represents the goddess’ wings and their power. A better name could not have been chosen for a company that has come to symbolize what this goddess represents: victory.
