While there were some very strict marketing rules put in place before the 2012 Games, one doctor is working around the situation. That doctor is Dr. Dre, the rapper and name behind Dr. Dre's Beats headphones. Dre chose to simply offer his Beats headphones to any Olympic athlete who wanted a pair, and really, who's going to turn down free Beats? Most viewers have noticed their favorite athletes are wearing Dre's headphones between performances, especially during swimming meets where the camera lingers on each athlete as they get ready to race. This kind of promotion is just what the doctor ordered.
