A brothel in Prague provides free sex in return for allowing the whole thing to be broadcast on the web to paying customers.
Big Sister is marrying 21st-century technology with the world's oldest profession to profit from the public's appetite for ever-more graphic reality TV. Since 2005, more than 15,000 men have taken up the offer of free sex in return for 15 minutes, or less, of fame, according to the brothel. Big Sister is now expanding into the U.S. with a local version of its Web site.
And suddenly, the web allows the economics of the world's oldest profession to be flipped on it's head. Very weird, but there is a lesson here. Sometimes paid services can be provided for free if you can figure out how a different party can benefit (and thus pay) from their use.
