J.K. Rowling launched Pottermore in 2011 as an interactive Harry Potter experience.
Pottermore was announced in June 2011 and opened to the public in April 2012 after an invitation-based early-access period. The website combined interactive moments from the books with new writing by Rowling, including background information about characters, places, and wizarding customs. It also offered digital editions and audiobooks through associated services.
The site’s name was later changed to Wizarding World Digital in 2019, and the main website became WizardingWorld.com. This means Pottermore and Wizarding World are closely connected, but they are not the same name for the original launch.
The project was notable because Rowling used an online platform to add officially written material beyond the seven main novels. It also helped create a central digital home for fans before the wider Wizarding World brand expanded to films, stage productions, games, and theme-park attractions.
