Have you noticed, that the TV size info is now typically: 65" Class, or some other fairly ambiguous term. They almost never really measure the actual dimension of the "Class" they include themselves in.

As a consumer, we've all become hardened to the marketing lies, and we don't usually even think about it. Feel free to ask your customer about when he goes to any large chain, that has commercials of the food, if he expects it to really look like that, when he receives it? Just look at a Big Mac, and then an advertisement for a Big Mac. You'd be hard pressed to imagine they were the same thing.
