Anna Todd's One Direction fan fiction has had over 800m views on Wattpad

"In the latest book acquisition to come from Wattpad, the popular online writing and reading community, Simon & Schusters’s Gallery Books imprint has acquired After, a three volume novel serialized on the site by Anna Todd, in a mid-six figure deal that includes world and audio rights. The new adult series was acquired by S&S’s Adam Wilson in an auction brokered by Wattpad’s head of content, publishing Ashleigh Gardner.
The first book in the three volume series will be released in print and e-book editions beginning in November 2014 with subsequent volumes released in January and March of 2015. The original version of the novel will remain on Wattpad.
Todd began writing After on Wattpad a little more than a year ago and the book has grown into a phenomenon attracting more than 800 million reads on the Wattpad site. The book has also garnered Todd a large following on social media. In April this year, Wattpad signed a deal with UTA, the talent agency, to represent film and TV rights for the novel."

Note - I'm assuming that 'reads' is Wattpad-speak for 'views'
