Sony Electronics and the Pinstripers announced Thursday that they'd signed an agreement designating Sony the official consumer electronics manufacturer of the Yankees. What's this mean? Well, Sony gets a prominent advertisement on the right-field wall (as well as a number of diorama ads in the concourse), and the new stadium gets over 550 Bravia and LCD HD televisions for the high-roller suites, and a PS3 gaming area in the park's "Strike Zone." Oh, also, the Yanks' new mascot is Polygon Man. That's a fair trade-off, right?
