In what genre did Kurt Vonnegut most often write?

Kurt Vonnegut began his writing career as a writer of short
stories published in local and national magazines. These stories were primarily of the science
fiction genre, and, even though he wrote a couple of science fiction novels early in his career,
he made the most money from writing the short stories.

This changed
when television swept the nation causing many people to lose interest in reading magazine stories
and serials. As a result, Vonnegut turned to writing paperback novels. Most of these were still
science fiction, but as a result of suffering tragic loss, he turned to writing autobiographical
introductions to these novels and even some general essays.

Critics
agree that within his stories' and novels' themes, Vonnegut employed satire, often asking the
question:

How can the
individual maintain dignity and exercise free will in a world overrun by death and destruction, a
world in which both science and religion are powerless to provide a
solution?

Vonnegut later went on to
republish his novels in hard cover form and to write plays and television screenplays. Later,
after his fame was firmly established, he became a much sought after
speaker.
