Nike originated from 1962 by Phil Bull; Knight started it, and then it was named Blue Ribbon Movement R, and it was officially renamed Nike in 1970s. 1980 occupies about 50% of the US market share, and initially surpassed Adidas to sit at the top of the US sports shoes industry. Since then, Nike began to implement aggressive marketing activities, signed top athletes, and created the slogan of "Just Do It" R. In early 2009, the Edison Chen brand Clot and the new red China sneaker Clot×Nike AIR FORCE 1 jointly signed by Nike were snapped up as soon as they were listed in Shanghai. In America, as many as 70% teenagers dream of owning a pair of Nike shoes.
