This week on Twitter, established and emerging writers everywhere created 140-character-sized fiction pieces as part of the annual #TwitterFiction Festival: “a celebration of storytelling on Twitter.”

The festival, which ran from May 11­­­–15, 2015, was organized by the Association of American Publishers and Penguin Random House. Featured authors Celeste Ng, Eric Jerome Dickey, and Margaret Atwood, among others, participated in the event. The first story was by Ng, whose debut novel, Everything I Never Told You, was one of last year’s most celebrated books; her Twitter fiction piece describes a love story left in library books.

In addition to the featured authors, the festival asked writers to pitch their own ideas and showcased the best 25. Those winners were selected by a panel of judges, including Corinna Barsan, Senior Editor at Grove Atlantic; Meghan Deans, Assistant Director of Social Media at Little, Brown and Company; and Andrea DeWerd, Marketing Manager at Simon & Schuster.

The #TwitterFiction Festival was first initiated in the fall of 2012, after other writers, including Pulitzer Prize winner Jennifer Egan, who tweeted a serialized short story for The New Yorker, had been dabbling in the form.

The festival also included a live event in New York City on Wednesday, May 13, hosted by the comedian Nick Turner. You can follow the festival with the hashtag #TwitterFiction.
