“Supposably”
Futile (as in expecting quality from a Braga produced series is _____)
oooh, and “anomaly”.
I was reading a lot fairly early, such as comic books and Asimov’s SF and science articles, so there wasn’t too much to pick up from TV or movies.
clairvoyance (the supposed ESP viewing ability): possibly from “Science Fiction Theater” or “One Step Beyond”.
nugatory, mordacious: two that I remember hearing from W.F. Buckley on “Firing Line”! 
How about tapes of radio plays?
instantaneous, semantic, aborigines, prognosticator, disseminator, illegitimate, hashish, psychoanalyst, strychnine: from tapes of two episodes of “X Minus 1”, the radio SF series. The episodes were “Early Model” and “Man’s Best Friend”. I wasn’t clear on some of the words until I was older.
superheterodyne: from a tape of the radio program “Mr. Magoo and the Hi-Fi”! (again, I wasn’t quite clear on the word until I was older.)
And of course, growing up in the 50s, we had only 4 TV channels and no VCRs, so there was much less to watch.
