A million paperback copies of the erotic novel Fifty Shades of Grey look likely to be sold by the end of the year.
According to the Daily Telegraph, the landmark figure should be achieved before 2012 comes to a close, after it became the quickest book to reach 550,000 copies in the same form.
It is also only the fourth novel of all time to rack up sales of more than 100,000 in a single week, confirming its place among the most successful publications in history.
Fifty Shades of Grey has been dubbed “mummy porn” by observers and details the erotic relationship between two people – a billionaire businessman and a college graduate
Fans will be delighted to know that it should be adapted for the big screen in the coming months, after Universal and Focus Features won the rights to make a film based on the novel.
It was recently said by the Daily Mail that a range of merchandise – including makeup and lingerie – based on the book will be released.
However, its run has not been without controversy, as some libraries in the US have taken the decision to ban it.
