Additional TV trivia:
--A former governor of Pennsylvania in the 1970s, Milton J. Shapp, made his fortune as a maker of cable TV components.
--In the waning days of WW II, IBM applied to the FCC for microwave channels so it could transmit data and television. Given the notorious conservatism of IBM's president at the time, Thomas J. Watson, Sr, one would have trouble imagining the broadcasted TV programs he would allow--probably classical music performances and Shakespeare (censored, of course), with commercials of IBMers singing "Ever Onward", the IBM song.
--There's a website out there that talks about the old Bell System microwave network, much of it now apparently dismantled. Several towers were dedicated to just television transmission. Indeed, does anyone know if AT&T or the other LD carriers still supply transmission facilities for broadcast television and radio networks? Or is it all done by satellite today?
--In Philadelphia, for about 50 years ABC was on 6, NBC on 3, and CBS on 10. Due to a switch in ownership and FCC regulations, NBC and CBS had to switch stations. When PBS came along, it had 12.
--In Phila, an independent UHF station, Ch 48, had internal ownership problems, and they ended up surrending their license back to the FCC. (Wasn't that a big loss of money?)
