I learnt during my studies (can't remember the exact name or details of it) that seeing a product through 7 different channels (print ad, TV commercial, etc.) will leave you under the impression of knowing and thus trusting a product. Of course other factors come into play, but in front of the yogurt aisle for example, (given similar tastes, packaging styles, prices, etc.) you'll be much more likely to buy the one you've heard of through many channels, rather than the one you've barely heard of. Even if you've tasted none before. If somebody recognizes this approach, I'd love to know the name of it Edit: it could be the mere exposure effect mentioned in the other comment, but I'm pretty sure the number of different channels had a play in the process.
