On-line source for TV listing archive? (1 Viewer)

[Nelson Au]

Ever since I got an iPad a few years ago, and even before that, I stopped buying TV Guide magazine and searched listings on-line, and now via the TV Guide app.
One downside to this is no listings past a day or two. For reasons of my own, I'd like to find a listing from a week ago. I tried the TV Guide website and on-line in a general Google Search. Plus I tried my local paper's website. So far, no luck in finding anything older then a day or two!
Anyone know a way to turn the time machine on and see what happened a week ago! I probably require a local listing too. Any insight appreciated, if possible. Thanks!

EDIT: DUH, you mean a current schedule. It's neat to see those old schedules though.
Taking a quick look at Wikipedia, this sounds like what you're looking for:

Thanks Travis, that is a neat source for general network schedules going back in time!
