How the mummy porn bonkbuster made bondage bankable
Having begun as a piece of fan fiction derived from the Twilight movie series, EL James's Fifty Shades of Grey has blown up into the publishing phenomenon du jour. It's supposedly the UK's fastest-selling book of all time, and has sold nearly 50 million copies worldwide. In the process, with its copious descriptions of BDSM (or bondage, discipline and sado-masochism), it has gathered a vast mostly-female fanbase and fostered the creation of the term "mummy porn".
