Fans of the series were so eager for the latest instalment that bookstores around the world began holding events to coincide with the midnight release of the books, beginning with the 2000 publication of Harry Potter and the Goblet of Fire. The events, commonly featuring mock sorting, games, face painting, and other live entertainment have achieved popularity with Potter fans and have been highly successful in attracting fans and selling books with nearly nine million of the 10.8 million initial print copies of Harry Potter and the Half-Blood Prince sold in the first 24 hours. 
The final book in the series, Harry Potter and the Deathly Hallows became the fastest selling book in history, moving 11 million units in the first twenty-four hours of release. The book sold 2.7 million copies in the UK and 8.3 million in the US. The series has also gathered adult fans, leading to the release of two editions of each Harry Potter book, identical in text but with one edition's cover artwork aimed at children and the other aimed at adults.
