>> u2, formed ten years ago when its members were still schoolboys, is now arguably the hottest rock 'n' roll band in the world. their last album "the joshua tree" has so far sold 13 million copies worldwide. >> u2 somehow in the video age were still developing and becoming a great band and maintaining that kind of connection with people and not getting the message lost in the medium. >> we spent the last ten years finding out how to be in u2. we'll spend the next ten years seeing what u2 can do. these folks, they don't have time to go to the post office they have businesses to grow customers to care for
