A T-shirt a day has kept unemployment away for an American man who is making about $85,000 a year by selling advertising space on his shirt．

Jason Sadler, 26, was once a former marketing expert from Florida. In 2008, he founded his own company, “iwearyourshirt”, with the idea to wear a T-shirt supplied by any company and then use social media tools to develop the company . Sadler charges the “face value”of  the day for his human billboard (广告牌) service. So January 1 costs $1, while December 31 costs $365. He said this may not sound like a lot, but it adds up to $66,795 a year if he sells out every day, which he did this year. He also sells monthly sponsorships(赞助) for $1,500, adding another $18,000 to his income.

“I walk around, take photos, wear the shirt all day … I blog about those photos, I put them up on Twitter, I change my Facebook introduction…and then I do a Youtube video. I made about $83,000 this year,” he told Reuters Television. The average U.S income is about $615 a week or about $32,000 a year ,according to the U.S government.

Sadler has already begun to plan for his year 2010. He is making services larger by hiring another person to wear a shirt a day on the west coast of the United States.
