NEW YORK (AP) -- Given a choice among the Police, John Mayer and Madonna on television or a summer's night out, millions of Americans chose the latter. The Live Earth concert, Al Gore's sprawling worldwide effort to raise environmental awareness, wasn't a big television draw. NBC's Saturday-night highlights show was seen by 2.75 million people, according to Nielsen Media Research, or fewer people than watched the soccer match between Argentina and Peru that night on Univision.
