The abbreviations are useful when comparing and contrasting the various different flavors of Trek, as in "Combadges weren't around in TOS. They were invented in TNG. And, by the way, how is your new DS9 novel going?"
And, for the record, I've never heard anyone try to pronounce "DS9".
It's always "Dee-Ess-Nine."
Again interesting. In conversation, I've rarely if ever met anyone who would actually say "TOS" or "T-O-S". Most people of my acquaintance wanting to make the distinction between the various series, say "original Star Trek" or "classic Star Trek", something like that. Or even "the original series" spoken in full like that. We usually say "Next Generation" or even "NextGen" rather than TNG; "Deep Space 9" or "DS9" (I'll give you that.) And Voyager is always "Voyager". Does anyone actually say "VOY" even if they write it like that?
