(My 4th post tonight -- can you tell I'm bored?) 
(1)When did TVG switch from using the "C" to denote color broadcasts to the opposite tack of using "BW" to designate black-and-white programs? I would assume it was around the time that the majority of the network schedules went color, but when did the switch occur, and was it uniform across all the editions at the same time?
(2)I have seen TVGs from the 60s in which one listed network affiliate had not yet converted to color -- let's say for argument that it was on channel 7. Throughout the listings, every time there was a color show, they would add the dislcaimer "Channel 7 does not colorcast" under the listing. I have seen TVGs where this was done dozens of times through a week's listings. Would it not have been easier (and saved a lot of ink) to just make note of the station's lack of color capability in the station list once at the beginning of the listings? Or would that have been too easily missed or skipped over?
(3)There seems to have been no uniform manner of handling translators over the years. In most cases, translators (if listed at all) were simply listed as a small appendix to the channel grid. But in a few cases, a translator's channel number icon was actually used in the program listings. (A good example is ch. 30 in New Britain CT, whose ch. 79 translator in East Hartford was for a long time listed thusly.) Was there some reason for the discrepancy -- just local editors' discretion, or what?
