PY: My point there was that even the authorities that allowed college, were dead-set opposed to television.
Agreed. Those signers (which BTW, were NOT the Gedolim of the time, and did not include Rav Moshe, Rav Yaakov or Rav Ruderman) were able to make a “Our camp” which excluded TV’s, and to a large extent, made it a signature issue.
Also, regarding college. There are “Charadi” Gedolim and Yeshivos that allow it, and those that don’t. As with other things, ask your own LOR.
