Would a German who speaks English in the early 1940's know the word TV? Seriously, I hate using slang if I'm not completely sure that it's proper for the era. For some reason I'm under the impression that it started in the 50's, but I'm not sure, and no matter how I try, Google is failing me. Badly.
Can I get a little help, please? :)
I tried things like "etymology of the word TV," "slang TV word," "history of the word TV," and pretty much any variation which I could think of apart from that.
