> 30 years ago, gay marriage would've been inconceivable by the majority of the US population. Gay marriage wasn't a major political issue 30 years ago, so I'm bet most people hadn't contemplated it. > Many of those same people who were against gay marriage are still alive! They must've been influenced by something - advertisements or not. Only if you think a significant number of them that are still alive changed their minds. I'd wager most didn't, but that they've been slowly dying out. I don't disagree that advertising has an effect, but I'm not sure that this a great example of that, because advertising tends to accelerate people down a path they were already headed in, whether to buy a product, or believe a political conspiracy, but rarely does it push people to completely reverse their direction completely.
