The Independent has an interesting story about an advertising technique known as "memory morphing" (Selling you a new past). Even if you didn't particularly like using a product, this advertising technique will help to mold your memories so that you "remember" liking the product. Experiments have shown people "remembering" meeting Bugs Bunny at Disneyland (highly unlikely - and unfortunate - I have to ask, where is the "Who Framed Roger Rabbit" sequel?), and recalling an orange drink spiked with vinegar and salt as "refreshing." One example of this technique in the wild would be the "Remember the Magic" campaign run by Disney.
