If you watch football,
506sports.com is a great source for comprehensive college and NFL TV listings.
Aside from info on every televised college game, 506 Sports publishes color-coded maps like this one every Wednesday during the regular season indicating what NFL games will be shown in which markets that weekend. This is an example; the real map will have a key saying what color represents each game. It's a very handy quick reference for planning your weekend viewing, both at home and if you happen to be traveling.
This is a great resource for anyone living out of market. A lifelong Saints fan, I'm in Falcons country of all places, but at least fortunate that the Saints are often shown in Atlanta if the Falcons aren't playing in the same time slot. Such is the case in Week 1 this season since Atlanta is at Philly in the Thursday night opener.
