And it is promotion. My publisher, Tor Books, have some modern methods that allow them to make a profit on as little as 3,000 copies of a hardcover novel. The traditional methods would need a print run of 50,000 paperbacks. That means Tor can afford to have tons of first novelists every year on much shorter runs. But then the marketing effort is diluted to cover all those authors. It's not possible to make a good living from being a mid-tier author, just selling in the bookshops. I need to promote myself, with all the tools I have.
