Gone is the reliance on top-down campaigns celebrating a single hit -- whether a star like Tiger Woods, a signature shoe like the Air Force 1, or send-ups like Bo Jackson's 'Bo Knows' commercials from the late '80s that sold the entire brand in one fell Swoosh. In their place is a whole new repertoire of interactive elements that let Nike communicate directly with its consumers, whether it's a performance-tracking wristband, a 30-story billboard in Johannesburg that posts fan headlines from Twitter, or a major commercial shot by an Oscar-nominated director that makes its debut not on primetime television but on Facebook.
