I blame the US TV series "Friends" for that.
Curiously the OED doesn't (yet) have this greeting sense.
Interesting, neither does my (more liberally accepting than Oxford) 2016 Collins. I've certainly been using it as an informal greeting since '00s.
I don't know if I got it from Friends, it wouldn't have occurred to me, but I did start watching it around that time so it's certainly plausible.
