>further advertisements for that product aren't necessary to reach you //

I'm one if those "advertising doesn't affect me" people. Except, then I realised that advertising acts subconsciously and uses human psychology against us, and I'm not as immune as I thought.

I buy a Dyson, every ad I see for vacuums is a Dyson, it confirms I made the right choice, everyone is buying them, they're everywhere, etc.. Everytime I see a shiny new vacuum it's a chance for my brain to compare it with the old rubbish one; why are all those people "enjoying" vacuuming when I have to suffer it.

With polo shirts it's like "these new ones look smart/fashionable/etc." vs the old one.

Yes there is likely a lag in "this person was looking for ..." signals; but I still don't buy (heh!) that as _entirely_ silly.

>Once I buy a car, or a television, I'm probably not going to be in the market for another one for years. //

Car, probably, depends on the person's wealth; TV, I've v heard people say "we liked it so much we got another one for our bedroom" or whatever.

FWIW I'd never buy a Dyson ...
