Actually, now that you have used that Taco Bell example, it makes a lot more sense. We have Taco bell here (or at least, we used to, haha... further exemplifying your point), and I actually had no desire to eat the food, but whenever I saw a chihuahua I would say the line "yu Quiero Taco Bell", thus showing that the ad did indeed provide a link between the customer and chihuahuas, but not the food. However, I would say it's not a terrible as you imagine. Cadbury's is already a very well established company, and does not necessarily need to score a bigger market. It is already a household name, so they have gone for the entertainment approach, knowing full well that they have an already solidified market. Basically, everybody will continue to eat Cadbury's no matter what, so they might as well attach a fun image to the experience.I won't eat any more or less chocolate as a result of the ad, but I will associate a positive image with Cadbury's as a result of the campaign.
