The guest on Episode 335 of the "Sports Illustrated Media Podcast" hosted by Jimmy Traina is Darren Rovell, the Senior Executive Producer for the Action Network. The main focus of the episode is the explosion in the trading cards business. From why the boom happened, whether it will last to the process of getting cards graded and selling them for profit, Rovell goes in-depth on explaining many of the aspects of the current trading card craze. He also explains that people are buying and selling more than cards. Game tickets, VCR tapes and checks are also in high demand. In addition to discussing the trading card world, Rovell and Traina also talk about the Super Bowl streaker who claims he won $375,000 on a $50,000 bet and the possibility of Twitter adding a pay service.
