Everyone always says sex sells, now there is proof that not only does it sell, but more and more ads in magazines are using it to sell products. Are you one of those americans that have been pursuaded to buy something that you saw and you saw it because a naked or mostly naked man or woman?

A recent study from the University of Georgia looked at sexual ads appearing in magazines over 30 years and found that the numbers are up.

"Advertisers use sex because it can be very effective," said researcher Tom Reichert, professor and head of the department of advertising and public relations in the UGA Grady College of Journalism and Mass Communication. "Sex sells because it attracts attention. People are hard wired to notice sexually relevant information so ads with sexual content get noticed."

There were 3,232 full-page ads published in 1983, 1993 and 2003 in popular magazines Cosmopolitan, Redbook, Esquire, Playboy, Newsweek and Time, researchers found sexual imagery in 20 percent of the ads. Using sex to sell everything from alcohol to banking services has increased over the years: 15 percent of ads used sex to sell in 1983; that percentage grew to 27 percent in 2003.

Ads were categorized based on the models' clothing, or lack thereof, and physical contact between models.
