In 2011, the odds are pretty good that no matter what market any of us posts from, the locals will be "Fox whatever" and "CW whatever" and "My whatever," and probably one or two of the Big 3 will be "CBS 5" or "NBC 27." (In my market, it's "News 10 NBC," "CW 16," "My 18" and "Fox Rochester," for whatever it's worth, along with "News 8" and "13 WHAM.")
What might be much more enlightening would be to find the markets that have retained local identities on a majority of their signals. I'll bet we won't come up with too many. Even San Francisco, which used to be pretty independent, now has "CBS 5" and "ABC 7" and "NBC Bay Area" (or is it "NBC 11" again?) and "CW Bay Area."
Seattle might be a good candidate - none of the Big 4 brand solely with the network identity. It's "KOMO 4" and "KING 5" and "KIRO 7" and "Q13 Fox," and even the My outlet, KZJO, is "JOEtv," not "My Seattle." If not for "CW11," KSTW, it would be a perfect example...
