On the heels of a court ruling that is expected to help Pandora cut royalty costs, Pandora’s stock recently hit an all-time high. Still, MediaPost columnist Bob Garfield doesn’t quite get why the market is so smitten with the Web radio service. Luckily for any investors at OMMA Global, Tim Westergren, founder and Chief Strategy Officer at Pandora, is happy to explain the company’s worth. Per week, the service accounts for more than 15 hours of the average American’s time, according to Westergren. “Consumers love this platform,” he said. “It’s that simple.” Oh, and Pandora is deadest on making more ad dollars per hour, which, Westergren added, it is doing with an ever more effective ad platform.
