Accent or Accentuation is when one changes the meaning of a statement by emphasizing or deemphasizing certain components of that statement. In the image below we see one of the classic uses of accent by advertisers. In each of these images from a TV commercial you can see the very fine print that flashes up at the end of the ad. The advertisers don't want you to see this information, but they are legally required to show it, so the solution is to flash it on the screen in fine print for half a second. Personally, I think advertising laws should be changed so that advertisers are required to present all information in the same font. But, given the influence advertisers and corporations have on the government, such a change seems unlikely. The takeaway: don't believe anything you see in an ad.
