The website J.K. Rowling launched in 2012 for Harry Potter readers was Pottermore.
Rowling announced Pottermore in June 2011 as an interactive online destination connected with the Harry Potter books. It offered readers access to additional writing by Rowling, including background information about characters, places, and the wizarding world. The site also included interactive features, such as choosing a Hogwarts house and receiving a wand.
Pottermore initially opened in a limited beta phase before becoming broadly available in April 2012. Its launch was significant because it gave Rowling a direct digital platform for publishing new material related to her books, rather than relying only on printed editions or film tie-ins.
In 2019, Pottermore Publishing was established, and the main website was later replaced by WizardingWorld.com. This change can cause confusion: Pottermore was the original name of Rowling’s Harry Potter website, while Wizarding World became the broader digital brand for the franchise.
