The launch of the PlayStation® brand was a sensation. In the very first weekend, more than 100,000 units were sold. In the first six months, over a million were sold. In April 1997, with nearly 4 million PlayStation® game consoles in North America, we found a way to strengthen our bond with PlayStation® owners even more. Our interactive relationship marketing program, PlayStation® Underground, gives us the opportunity to recognize and reward our loyal gamers. Members of the PlayStation®Underground can feel as though they belong to a subculture of intense gamers by experiencing new game challenges and getting the scoop on upcoming games, merchandise, and special offers.
