Nike has unveiled a brand new “Possibilties” campaign inspired by the “Just Do It” campaign which debuted 25 years ago. Taking the “Just Do It” motto to its logical conclusion, the new “Possibilties” campaign spurs people to challenge themselves to the max. The new campaign video features a stellar list of cameos including LeBron James, Serena Williams, Gerard Pique, Andre Berto and actor Chris Pine, with narration provided by actor Bradley Cooper. More than just a video campaign, “Possibilities” looks to inspire people to be their best with special challenges for Nike+ Running and NikeFuel.
