Re: Is fantasy more popular than science fiction? If so why?
Most of the stores I've worked and shopped in have placed Science Fiction and Fantasy together, usually under the heading "Science Fiction." To the General Public there might not be a difference. Big name authors will usually wind up where they made their "mark". No matter what Stephen King writes it wind up on the horror shelves. If Danielle Steele writes a SF novel is gonna wind up in Romance.
I'm sure there are stores out there who are more stringent and go strictly by content.
The boring one, the one with Khan, the one where Spock returns, the one with whales, the dumb one, the last one, the one with Kirk, the one with the Borg, the stupid one, the bad one, the new one, the other one with Khan.
