My mom took classes on tv to learn to pass the citizenship test. That was in the very early 1960s I think.
So even if there wasn't a PBS in present form, there was educational programming out there, most likely on uhf channels.
I'll ask her about it.
I just want to say that I would die a happy man if I could punch Howard Wolfson just once.
Did Edwards say it was PBS? I have it on TiVo and I'd watch it again, but I just had cashew chicken and steamed rice, and I think I might lose it if I have to listen to that summation one more time. ; )
