A story by Pulitzer Prize-winning author Jennifer Egan for the New Yorker is being serialised in 10 installments on Twitter, according to the magazine.
The New Yorker said the first installment of the story, a spy thriller called "Black Box, went out on Thursday night.
"The story is written in terse dispatches of 140 characters or less, which will be tweeted, through The New Yorker Fiction Department's Twitter handle, @NYerFiction, in ten nightly installments between 8 and 9 P.M. E.T," it said in a statement.
After the tweets are complete they will also appear on the Page-Turner blog on the magazine's website, and the entire story will be published in the next edition of the magazine which will be on newsstand on Monday.
Egan, who won the Pulitzer Prize for Fiction in 2011 for her novel "A Visit from the Goon Squad," said she had been thinking about how to write fiction that could be serialized on Twitter.
"This is not a new idea, of course, but it's a rich one - because of the intimacy of reaching people through their phones, and because of the odd poetry that can happen in 140 characters," Egan said in a post on newyorker.com.
