We've all seen those ads from way back when that make you want to laugh and hurt someone at the same time. The ads that imply women are helpless, fragile creatures, the ads that say you should give your baby soft drink instead of breast milk, the ads that say smoking cures throat conditions.
But do you ever stop to think about what ads we are showing now that, 50 years from now, will be horrifying? I don't mean the occasional one-off ad (there are a lot of really sexist deoderant ads, at least here) but a whole recurring theme in advertising.
One possibility that comes to mind are junk food ads. They are often pitched at the idea that buying deep fried synthetic proteins will bring your family together. With obesity being health problem number 1, I bet future generations will be asking themselves "what the hell were they thinking?"
Some car ads, perhaps? A lot of car ads are emphasising either environmental friendliness or safety, but compared to the tech they will hopefully have, even the best of our cars will be stinking toxic death traps.
Oil companies being responsible... well, that is already looking ridiculous.
Any others?
