In the 1970s, Nike captured the US market by creating sports icons. In the 1980s, Reebok capitalised on the jogging fever. In the 1990s, Nike has struck back with its high-profile endorsements and has been stretching the lead since. Today, both flaunt impressive endorser lists. If Nike has an Andre Agassi, Tiger Woods and Michael Jordan, Reebok has Shaquille O'Neal, Michael Chang, Jurgen Klinsmann. Nike surged ahead with its Air technology, but Reebok has replied emphatically with its DMX series 2000. Now Nike is getting into events sponsoring and refocussing on apparel. Meanwhile, stories of the rivalry keep getting juicier.
