"It's just like "I Love Lucy" seemingly having run its course of late."
Not in Los Angeles - KTTV (Fox 11) not only runs I Love Lucy daily, but also runs the later 1 hour "Lucy in Connecticut" shows.
The episode I saw recently featured Lucy, Ricky, Fred, and Ethel all sitting around adjusting the TV set, each one arguing about the proper brightness, contrast, vertical hold, etc. It was probably screamingly funny back in the early 50s when TV was new technology for Americans. It was VERY dated, but it was still funny> Of course, I'm 55 and still remember having to adjust the TV.
It's interesting that Maude reruns were canceled for being dated, but the equally dated "All in the Family" ran for years until recently despite scripts that (for example) featured Archie and Meathead arguing constantly about Nixon and Vietnam, etc.
