NBC decided not to air these PETA ads during the Super Bowl, considering them too racy. While they are plenty of over-sexed ads shown during Super Bowls, I do think these go too far. So we have questions of both censorship and animal rights. Decide for yourself on the ads here.
Of course the point of the ads (effective even if they are not aired) is to spark discussion about the morality of eating meat. I think the ad listed on the page called ‘Chew on This‘ is much more effective.
