I'm so old, I remember the disappointment, when the Buffalo Bisons of the International League had their road games on radio. Must have been 7 or 8 years old!
Found out there was no 'booth'... the pitches/plays were sent to the studio on "Ticker Tape" and that the play-by-play guys were acting them out...emotion and all!
No different than today, not having FIOS or CABLE TV and getting the play-by-play on ESPN internet and pretending that you're broadcasting the game in real time.
