...a few comments about then-indie WVTV/18 Milwaukee carrying late night programming from NBC, ABC and CBS at various times in the '60s, '70s and '80s just made me wonder, what other independent stations did that during the same decades? The ones I definitely know of are:
WVTV/18 Milwaukee: ran Joey Bishop and Dick Cavett from ABC, Merv Griffin from CBS and Johnny Carson from NBC
KFIZ-TV/34 Fond du Lac WI: ran Griffin (retransmitted WVTV's day-later delays, in fact)
WLRE(WGBA)/26 Green Bay: ran The CBS Late Movie/CBS Late Night (didn't they also carry Fridays from ABC?)
WKBD/50 Detroit: ran Saturday Night Live from NBC (didn't they carry Tomorrow with Tom Snyder at one point as well?)
