This fish looks like you caught it except it sings you a little toon. This fish has absolutely no purpose in the world, but as soon as I saw that fish, I had the phone in my hand. Luckily you cannot pay with money order, so I didn't get the fish, but they sucked me in. Advertisers do this all the time, and that's why they get paid so much money. I can't think of a better example of advertisers pushing junk on people than car dealers.
Car dealers sell people useless features for their cars.
You don't need power locks or power windows, but they will have you believe that you just can't live without it. A company that I can point to is Lexus. They obviously do not appeal to people with a budget. Lexus promotes comfort and luxury. They make it seem like the car that they sell is only for the rich.
