‘Harry Potter’ Is Turning 20 Years Old

As the boy-wizard series hits a publication milestone, fans in their 20s and 30s are celebrating—and passing along Pottermania to their children

The “Harry Potter” series is hitting a milestone next month with the 20th anniversary of the first Potter book’s publication in Britain.

U.K. publisher Bloomsbury is coming out with a special edition of “Harry Potter and the Philosopher’s Stone”—the volume’s title in Britain. To mark the June 26 anniversary, Bloomsbury is offering party packs with puzzles, games and a display of the three main characters that bookstores and libraries can download free. The publisher also is working on events such as “Harry Potter: A History of Magic,” an exhibit at the British Library, set to open in October.

The books have sold 450 million copies world-wide, 167 million of them in the U.S., according to Scholastic Corp., their American publisher. “Harry Potter and the Deathly Hallows,” the final volume, has been the top-selling print book in the U.S. since 2004, according to NPD Books, outselling hits such as “Fifty Shades of Grey” and “Twilight.” The orphaned boy’s adventures at Hogwarts School of Witchcraft and Wizardry have spawned merchandise, theme parks and $7.7 billion in global box-office receipts, according to Time Warner Inc.’s Warner Bros.
