Fifty Shades of Grey breaks print sales record
THE 'mummy porn' book Fifty Shades of Grey has become the fastest adult paperback to sell one million print copies.
It's been a digital publishing phenomenon, with sales of the novel on the Kindle reaching one million earlier this week, but now Fifty Shades of Grey has broken print sales records too.
The trilogy has sold one million print copies in 11 weeks, beating The Da Vinci Code's previous record of sales of one million in 36 weeks.
According to Nielson Bookscan the book has also broken the weekly record for paperback sales, selling 397,889 copies.
The book beat JK Rowling's The Tales of Beedle the Bard, which sold 367,625 copies in 2008.
EL James's novel has been dubbed 'Mommy porn' due to its steamy plot lines. James, who was a former self-published Kindle Direct Publishing author said the books offer women a "holiday from their husbands".
The book is currently the 32nd bestselling book since records began in 1998.
Earlier this week Amazon confirmed that the novel had become the first ebook to sell one million copies for Kindles.
Author Dan Brown holds the record for overall weekly adult sales for The Lost Symbol hardback which sold 590, 964 copies in 2009.
JK Rowling still holds the single week record across all genres, for the last in the Harry Potter series.
