This week on our Summer Series, we look at Marketing Dead Celebrities. It's become a $2 billion dollar industry. And the marketing of dead celebrities not only attracts lots of big brands, but lots of controversy. We'll trace the use of dead celebrities in advertising, we'll analyze "Dead Q Scores," we'll list the top-grossing dead celebrities, and we'll tell some amazing stories about ads that featured Audrey Hepburn, Michael Jackson, Fred Astaire and Marilyn Monroe - and how their families felt about those commercials It's a brave new world, now that nobody's dead anymore.
