Short form science fiction is doing well.
The established magazines (
Analog,
Asimov's) have seen falling circulation, but there are several other magazines out there, several electronic-only ones.
There's the UK's
Interzone, the semi-pro
Clarkesworld and even the free
Hub Magazine, Clarkesworld.
The longer form does seem to have fewer titles coming out — paranormal is certainly the current fashion, and epic fantasy is still going strong.
But I don't see it dying out anytime soon.
