Singer M.I.A. flipped off millions of viewers during her performance (with Madonna and Nicky Minaj) at halftime of the Super Bowl broadcast in February. She also uttered (or lip-synched?) an obscenity, which was inaudible. Both NBC and the NFL condemned the act, but the NFL went further, pointing a finger of its own at the broadcaster for an ineffective video delay system that failed to zap the M.I.A. gesture.
