Title says it all, I heard a while back on G4 that ICANN is releasing new TLDs and gTLDs, so what are they and when will they be available?
When will they be available: Don't know! As for what they are, they are going to be anything you can think of, to a reasonable degree. Anyone can register any extension they want aslong as they can provide grounds for wanting it, and have a substantial amount of money to invest!
