I'm wondering if Knoxville is unique. The CBS affiliate, WVLT, airs Black and White episodes (maybe color too I don't know) of the Andy Griffith Show--not on a subchannel, not at 4am, but T 7:30PM, against Jeopardy, Judge Judy and others. Not to be outdone, the NBC affiliate, WBIR, airs I Love Lucy at 12:30. Kinda cool that these shows are on major affiliates in good time slots. I'm not familiar with other markets with this situation...are there?
