I'm thinking something that happened in 2009 was influential :-)

From a purely descriptive perspective, "ranked choice voting" is voting
which involves choices arranged in ranks, so pretty much every kind of
ranked ballot would count. I'd be inclined to suspect that FairVote
calls IRV RCV to try to cement a link between ranked voting (the ballot
format) and IRV (their method).
I don't see that there's a reason to do this. I'd suggest that RCV or
Ranked choice voting direct to some page about ranked balloting, and
then have a Wikipedia-style disambiguation line at top saying something
like "This is about the ranked ballot format, to see the method FairVote
calls Ranked Choice Voting, go to [Instant Runoff Voting]".
To try to be generous to the other side, I could say that some methods'
names aren't entirely descriptive (e.g. Ranked Pairs), and that "ranked
choice voting" (why not just "ranked voting"?) is an odd term for the
general concept of ranked balloting. Such arguments would strengthen the
case for letting FairVote use RCV as a brand name for IRV/STV. But on
the balance, I think doing so gives FairVote too much of a say in just
what method ranked balloting should use.
