Is this on air like broadcasting or literally on the air?
like broadcasting :)
"on the air" should be accepted as well, reported on Nov. 25, 2017.
the dictionary hit is actually "on the air" - and it's STILL not accepted. reported 12/11/17.
Can't I say "live" here?
Live can mean on air, but when you look at it strictly, live would mean a live broadcast, which would be 생방송. slight bit more inclusive than just on air altogether. though we would just say on tv, 테레비에서 or 티비에서.
Learnt this one from watching Korean variety :D
"On the air" should be accepted - no one says "on air" - reported November 29, 2020. Someone reported it 2017 and nothing has been done lol
