So what's new on the networks this fall? We're preparing our own TVWW fall preview, but in the meantime, you can find out from the networks themselves. They've all produced half-hour fall preview specials that are unreeling on local stations and related cable channels -- not to mention online in various formats.

Local affiliates usually run the specials at odd times whenever there's room on their lineups, although 2011's CBS Fall Preview gets a prime-time slot on the full network Thursday at 8:30 p.m. ET. So what you'll see listed below are times to see the fall preview specials on New York affiliates -- check your local listings to find them where you watch.

Or look online. You'd think the networks would make them easy to find there, but no. Their web sites still tend to stream bits-and-pieces clips, rather than the polished half-hour encapsulating their approach to fall 2011.

Too bad. These fall preview specials have a great history. (Read about it in this clip-filled retrospective.) The star-laden wraparounds that packaged fall clips from '50s-'60s schedules have been showing up among DVD extras on sets like Get Smart, The Lucy Show and others, and they're always a cheesy showbiz delight.

Here's where to find the fall preview specials of 2011 (all times ET):
