I've long been interested in the meaning behind the unique logo used by North Carolina's public television network, UNC-TV. I actually asked on a tour at the station 21 years ago what the logo represented and the tour guide didn't know for sure, only that it was designed by the same folks as the CBS "eye" and that the consensus around the station was that it was either a hurricane or quotation marks. I wondered if maybe it represented an abstract "4" representing flagship station WUNC-TV in Chapel Hill--on channel 4 from 1955 until the DTV shutdown two years ago. New Hampshire Public TV's logo obviously represents the letters "NH" and an "11", and their flagship, WENH-TV in Durham, operated on channel 11 (and may still...I'm unsure of their DTV assignment)
