Well, that has changed recently with the discovery of the TVU Player, a free program that lets you watch "live" TV on your computer--for free! If you're currently in Korea teaching English or anywhere else in the world, you might enjoy this. According to the review from WebTVHub "Channels featured on TVUPlayer currently include CBS, ESPN, NBA TV, ABC, NBC, FOX, Comedy Central, Disney and more, including sports channels."
It might not work for you in your region, but it's been great for Gdog. Check it out!
