What is "blank!"

Blank! is a science fiction short story by Isaac Asimov. It was commissioned by Larry Shaw, editor of Infinity Science Fiction, as being the least inspirational title on which to base a story. Harlan Ellison and Randall Garrett were also invited to submit stories based on the same title; Garrett wrote one with "Blank?" as the title while Ellison submitted "Blank." All three were published in the magazine in June 1957. Asimov's story was later reprinted in the 1975 collection Buy Jupiter and Other Stories.
