Guy A is a big baseball fan. So big that he travels from St. Louis to Cooperstown to visit the Hall of Fame. He's walking around the museum when he gets to the plaque for Catfish Hunter. Halfway through the third sentence on the plaque, Guy A drops his coffee in shock. He lifts his camera over his head and brings it down on the plaque with the force of a thousand suns. Tears stream down his face as he shouts, "that's it. That's it. I quit. I quit you baseball. Too many players are in this museum I just traveled 1000 miles to see. Soccer is my new love. I heard they showed a soccer match on Fox instead of the Yankee game last Saturday."
Guy B lives in Los Angeles. He is not much of a baseball fan. He checks in once and a while during the playoffs and goes to a game with friends about once a year. He wouldn't be able to name the shortstop for the Yankees. He gets a marketing email from MLB because his cable company shared his email address, despite him unchecking the permission box when he ordered HBO last month. For whatever reason, the email doesn't get routed into spam like it normally does and he opens it.
The email explains to Guy B that MLB has embarked on a new mission designed to attract people like him, people with only the slightest passing interest in baseball. How is MLB going to accomplish this? They have undertaken a revolutionary revamping of the Hall of Fame. No longer will you find marginally famous baseball players who produced enough on the field to be considered among the best of all time. Instead, the new Hall of Fame will consist of a handful of players you may or may not have heard of. These players played baseball mostly in cities like New York and Boston. Where they the best players? Probably not. But they're famous, at least famous to people who already love baseball. Maybe not to Guy B but, you know, details shmeetails.
Guy B decides on the spot that, because of the changes to the Hall of Fame outlined in the marketing email, he is now a baseball fan. He buys a Derek Jeter jersey online and waits everyday outside his house until it is delivered. He subscribes to the Extra Innings package, quits his job, and watches every single game. Baseball is saved.
