It's about 20 billion a year, marketing that is, making it less than a percent of medical expenses. Anyway, that's fine in free-market, that advertising would have to be replaced at least in part with other efforts at public awareness if it was gov't run, and the money spent pays for television, radio, magazines, webistes, etc which we'd otherwise have to go without or pay tax dollars for. So ironically it pays for consumer safety reports too.
