i think the issues i'm getting at are a bit of both.
I agree. This thread seems to have an unusual fascination for breakfast cereal, so I'll use that as an example. Marketing clearly aims to attract the consumers attention in any way possible. How are you going to decide what cereal to buy?
Well, just go to the supermarket and you'll see cereals in a huge range of different sized boxes, colours covering the full spectrum of the rainbow, various logos and animal 'mascots' with catchy phrases, all designed to draw your attention. I'd consider that a sensory overload, especially for young children.
Then there's the information overload. We're grown ups now, and we don't get drawn into such gimmicks as easily as we used to. Companies are taking a more information based approach - hmmm, should I get the cereal that contains 30% less fat? Or the one which provides 20% of the daily dietary intake of iron and niacin? Or the one with the low glycemic index? How about the one which uses recycled packaging - that's gotta be good for the environment. Oh, but this one's proudly owned and produced in the US. Decisions decisions. i.e. information overload.
Even now, half the time when I buy something (mainly larger products, such as coffee machines etc.), I have doubts after the purchase and wonder 'maybe I should have gone for my second choice, it did have this nifty feature - or even the third choice, it was a bit cheaper' etc.
