Ok, so this will show you how big a dweeb I am. When I was really young, there were two pieces of mail I loved getting more than anything else. One was the Sears Christmas Wishbook. I can remember sitting on the couch with my mom and going through the whole thing, cover to cover, picking out what I wanted for Christmas. That's actually a cool memory. The other was the Fall Preview edition of TV Guide. I used to go through every day, picking out what I thought would be the hits and misses. (See...dweeb)
So when I find a site that has images of every TV Guide ever published...well, I know what I'm doing for the next hour. And If you're anywhere close to this level of dweebiness, you may get a kick out of this, as well.
