What online reading platform did J.K. Rowling launch in 2011?

J.K. Rowling launched the online reading platform Pottermore in 2011.

Pottermore was announced in June 2011 and opened to the public in April 2012 after an earlier limited registration period. It offered interactive features connected with the Harry Potter books, including house sorting, wand selection, and supplementary writing by Rowling.

The platform was created with Sony and was designed to combine digital reading with an interactive fan experience. Users could explore illustrated moments from the novels and access background information that was not included in the original seven-book series.

Pottermore was later rebranded as Wizarding World Digital in 2019, and the wider official franchise website became WizardingWorld.com. Because of that change, Pottermore is the historically correct name for Rowling’s original platform, while Wizarding World is the later brand.
