From the Wall Street Journal: The Death of the Slush Pile.
Getting plucked from the slush pile was always a long shot—in large part, editors and Hollywood development executives say, because most unsolicited material has gone unsolicited for good reason. But it did happen for some: Philip Roth, Anne Frank, Judith Guest. And so to legions of would-be novelists, journalists and screenwriters—not to mention “D-girls” and “manuscripts girls” from Hollywood to New York who held the hope that finding a gem might catapult them from entry level to expense account—the slush pile represented The Dream.
Now, slush is dead, or close to extinction.
