Beginning last month, live video streaming of major league baseball games has been available via the popular $9.99 MLB.com At Bat 2009 app. Initially one or two games a day were available for free via streaming, with plans to roll out more and more games as the summer progressed. Baseball games are subject to local blackout, just as with broadcast TV. You can read more in a short article in the New York Times. It works on an iPhone or iPod touch, but you'll need to have iPhone 3.0 software, and likely also a 3G or WiFi connection. And according to an article in Silicon Alley Insider, a forthcoming app from DirectTV, Supercast Mobile, live streaming of NFL football will be coming this fall. Unfortunately, it will be quite expensive. It's only available to DirectTV satellite subscribers. And you'll need a $280 NFL Sunday Ticket subscription, as well as a $100 Sunday Ticket "SuperFan" subscription. Ouch.
