J.K. Rowling’s website and digital fan platform launched in 2011 was called Pottermore. It offered interactive material, new writing, and a digital reading experience connected with the Harry Potter books.
Pottermore opened to the public in 2012 after an initial registration period. Rowling contributed new background information about the wizarding world, while users could be sorted into Hogwarts houses, receive wands, and explore locations from the books.
The site was renamed Wizarding World in 2019 as the official digital brand expanded beyond the original Harry Potter material. Because of that change, Pottermore and Wizarding World are related but are not interchangeable answers to a question about the original platform’s name.
