In Chicago, it might be possible for WTTW to survive without CPB funding, but who knows about WYCC, which is owned by the City Colleges of Chicago. I read many years ago about this very issue that WYIN receives 30-50% of their funding from CPB. A total elimination of CPB funding would force them to reduce their broadcast hours, and eliminate all local programming. They already fill their overnight hours with pledge drive programming, or they'd just sign off at night. I'm concerned that WYIN might rely on it more during the daytime hours too. I know WTTW will rely on pledge drives more often if it happens. I just hope they don't do double pledge drives on WTTW 11 & WTTW Prime at the same time. They usually hold pledge drives on one, or the other. If on WTTW 11, then most primetime programming gets moved to WTTW Prime. If on WTTW Prime, the regular schedule on WTTW 11 doesn't get interrupted. I just wonder if WYCC would be forced to cave into holding pledge drives regularly. I believe they only hold 3 or 4 pledge drives a year, while they typically ask for people to donate money to the station between promos for only a minute or 2.
As for PBS, I believe there's still a need for it, as commercial broadcasters don't really want to support children's programming that commercial broadcasters have nearly eliminated. Other programming they carry isn't necessarily available anywhere else. It might be true that certain types of programming are available on the cable/satellite chanels, but that requires a subscription to pay TV. Not everone can afford the high rates for pay TV (I'm one of those people right now). PBS fills those needs for those people. I watch PBS more than any commercial TV station. Now as for allowing PBS stations to be allowed to accept advertising, would require the FCC to change the licenses of PBS stations from non-commercial to commercial. Until that happens, that won't happen. I don't believe they're allocating new non-commercial licenses The Chicago market used to have 5 channels allocated as non-commercial, but only 3 ever signed on. I believe the other 2 have since been deleted, as there no takers.
