Read this excerpt from a passage:

"Five thousand! That's about how many advertisements you are exposed to in one day if you live in a metropolitan area. Researchers' estimates of the actual number vary from three hundred to six thousand, but everyone knows that ads are everywhere. Advertising goes down the street with us; it's on trains, planes, and buses. It shouts at us at sporting events from the banners on display and the electronic scoreboards. Advertising takes the form of brand names and logos on our clothing and accessories. You can't even turn on the television or check out your favorite website without watching an advertisement. At every point, advertising shouts, whispers, or cajoles us to 'Look at me! Buy me!' But how exactly do advertisements do it? As it turns out, just a few formats characterize the majority of ads."
