A great deal of advertising is done to establish/reinforce image and name recognition, which only secondarily lead to sales.
Instead of asking whether an ad makes you want to buy the product, ask yourself if the ad left you with a good impression of the brand. If it did, you are more likely to choose that brand when faced with a buying decision.
Well actually, when I see ads that don't address what the product is, what good it will do me, I'm not left with a favorable impression.
Take those 3 condom ads. The 2nd didn't leave me with a favorable impression. The 3rd one was very funny, I guess you could say I was favorable of the commercial, but it didn't even make me think of condoms first. Well, it did, but in the fact you can make them into balloon animals. Even though they were having sex, I myself wasn't thinking about sex watching it.
The first one though....THIS is what happens without using condoms.
THAT was ALL I needed to know.
