Song of the Day: "Flash's Theme" by Queen
It appears that there is not very much information available on flash fiction, and I can't seem to get a straight answer. I think it is a form of fiction that at one time, was not very popular, but is now beginning to grow. People have less time these days to sit and read a whole novel. With the always changing influence of modern technology, flash fiction is not a bad way to go. If you're familiar with Narrative Magazine, you'll know that they recently introduced the "istory." It's a new application created for apple where readers can read a complete story that is under 150 words.
Flash fiction is also sometimes referred to as "micro fiction," "sudden fiction" or "short short story." Sudden fiction is considered to be longer than flash fiction and micro fiction is considered to be shorter. A thousand words seems to be the cut off between flash fiction and sudden fiction.
In my opinion, flash fiction is still evolving and so far, I like what I see.
