>Before someone says I'm being "tricked in a deeper level" and buying other stuff without noticing, I don't pick brands.

"My, my, that's a spicy meatball"

It was an alka seltzer commercial, didn't help with their sales, but sales of spaghetti supposedly increased at the time. Just because the advertising didn't work for its intended purpose doesn't mean the advertising didn't work on you. The manufacture selling the ad wants you to go to the store and think about fish because there is a good chance you will buy their product. The manufacture buying expensive ads also tends to have the bright colored boxes in the store, they are placed at eye level, there are likely other ad campaigns in the store to direct you to their product. In the end there is a higher probability of 'an average person' buying their product over the other brands. The other fish brands get sales benefit at their competitors expense.
