Inside The World Of Call Girls

It's known as the world's oldest profession, and evidence shows prostitution's success still knows no bounds.

CBS News Chief Investigative Correspondent Armen Keteyian reported on The Early Show Wednesday that the sex scandal enveloping Eliot Spitzer has again put the spotlight on the multi-billion dollar industry, which is being aided immensely by a comparatively recent tool -- the Internet.

One search for "call girls" turned up more than 12 million hits -- 2-and-a-half-million for "escort services" alone, Keteyian says. On the wildly-popular Web site Craigslist, go to Services/Erotic, then search under the right "code word," and you'll find no shortage of sex for sale, Keteyian points out.

Today, he adds, sex knows no bounds: The Super Bowl, heavyweight title fights, NBA all-star games, political conventions -- "all havens for high-priced hookers."

Ex-call girl Tracy Quan, who wrote "Diary of a Manhattan Call Girl," gave Early Show viewers a glimpse at her former profession Wednesday, telling co-anchor Maggie Rodriguez about things such as the difference between an escort service and a private "madame," which ones the most powerful men tend to frequent, who's most likely to look for the kinkiest services, and what call girls think of their clients.
