I agree - either embrace the entirety or eliminate it completely. Here you have incredible libraries - use them! Cigarette ads, etc. It's history, not paid advertising. Jeesh - you don't see PBS stations blanking out "Plymouth" or "Geritol" on the reruns of Lawrence Welk shows.
Give the audience what they want - a mix of old and new is okay but when the focus on new is over-emphasized, the focus of the channel is lost. I don't buy the "cost of rights" mumbo-jumbo. I deal with rights acquisition in my job. They've paid for the rights. Kill off the informercials, package the daytime like what was done in the past and blow off the dust of the libraries. Give the programs some equal usage (no 3's a Crowd mega-marathons as example). Run TPIR, Joker's Wild, Hollywood Squares and other items not ran or "thought to be lost". Run the Goodson/Todman collection. Crank up the quad and dub away. Open up the purse and buy Sugarman's and Ralph Edwards libraries (or rights to them) - show some commitment.
