Public launch
Pottermore was originally scheduled to become publicly available at the end of October 2011, but the beta period was extended. The Pottermore Shop (which sells Harry PottereBooks and digital audio books) became available on 27 March 2012. On 8 March 2012, it was reported that Pottermore would open to the public in early April 2012. The website officially opened on 14 April 2012, but at that time, the interactive experience was only available for Harry Potter and the Philosopher's Stone.
