Repetition

This photo of a diet pill bottle shows the type of advertising called Repetition. People use repetition because while you are watching a commercial, you may not be paying that much attention to what they are doing, like if you are cooking supper or something else along those lines, but your ears are tuned in to every last word on the TV, they keep repeating the name of the product so that it sticks into your head and even later on while you are trying to think of the name of the product you were hearing about the name is so burned into your brain that you couldn't forget it if you tried. But I think that companies use this type of ad for that specific reason...if they can get the name of their product to stay up in your head, they feel that there is a better chance of you to buy their product instead of someone else's.
