Pottermore from J.K. Rowling is the digital platform for Harry Potter where Harry Potter fans can go to discover exclusive new writing by J.K. Rowling, including sub-plots, character backstories and her thoughts on writing the books. Fans can also follow Harry's story through a series of beautifully illustrated scenes called ‘Moments’ and embark upon a magical journey of their own; have a wand choose them at Ollivanders, discover which house the Sorting Hat will place them in, take part in potion-brewing, wizard dueling, and much more. Designed to appeal to both existing fans and those who are new to the stories, it is enjoyed by millions of adults and children around the world. Pottermore provides an official online platform for Harry Potter fans to come together and discuss the series. Pottermore goes to great lengths to ensure its social media content is available to fans of all ages, even integrating a moderated Twitter stream into the blog (for under 13s) when necessary. As well as engaging day-to-day with fans across Twitter, Facebook, SoundCloud, YouTube and the blog, Pottermore ensures its followers are first to hear relevant news, including the release of new J.K. Rowling writing and behind-the-scenes content such as interviews, early sketches, and time-lapse videos showing how artwork gets from the sketch pad to the final polished image. The House Cup, for which members of the four Hogwarts houses compete, is awarded several times a year. Pottermore uses social media to amplify displays of house pride by providing house-branded assets for users to broadcast their Gryffindor, Ravenclaw, Hufflepuff and Slytherin pride in social channels.
