For the most part, I think American television is too prudish when it comes to commercials. Oftentimes, I'd be watching a show on banned commercials, and for the most part, I'd agree that some are too sexy, with others I wind up thinking, "What's wrong with THAT!?!?!"
The "what's wrong with that" part is that if they are aired when young kids can see them. If they are on HBO or something like that, whatever. While parents SHOULD be monitoring their kid's television viewing, your TV parental controls can't exactly be set for blocking lewd commercials......unfortunately!
Children are privy to entirely too much sex education via the television now. Commercials along the lines of those pics are just TOO MUCH!
