I heard about this site from Chris. On the Couchville site, you enter your zip/postal code, choose how you view TV (cable, satellite, or over-the-air antenna), and then choose your provider (if you have more than one option in your area). You then are presented with an AJAX-based TV programming schedule. You can drag the grid around to move up and down the channels or move forward or backward in time. It’s very cool.
