PSP users 'urban nomads'

Sony has commented on its controversial graffiti ad campaign and said the street art was targeting its core city dwellers. "We're really looking at our target as urban nomads," Sony spokeswoman Molly Smith said in an interview with Reuters. While the campaign, which was launched in seven markets from Los Angeles to Miami, spawned charges that it undermined the credibility of street art, Smith said it reached target buyers.
