Sao Paolo Bans Outdoor Advertising

This is not the city's first effort to regulate outdoor advertising. A few years ago it was prohibited in the historic downtown area. But there have been complaints about inspectors taking bribes and advertisers simply flouting the law.

"All our efforts to negotiate have had no effect because none of the accords and agreements we reached with the advertising sector were ever complied with," Mayor Gilberto Kassab said in an interview. "A billboard that was forced to come down would be back up a week later in a different spot. There was a climate of impunity."

Since "it is hard in a city of 11 million to find enough equipment and personnel to determine what was and wasn't legal, we decided to go all the way, to zero things out," Kassab said. "When you prohibit everything, society itself becomes your partner in enforcing the law" and reporting violations.
