As of August 2018, a staggering half a billion Harry Potter books had sold worldwide, *********** of which were sold in the United States. British author J.K. Rowling published her first book, ‘Harry Potter and the Philosopher’s Stone’ in the United Kingdom in 1997, and the American edition was released in the following year – with some changes.

Changes to J.K. Rowling’s novels outside the UK

In the United States, India, and Pakistan, the title ‘Harry Potter and the Philosopher’s Stone’ was altered to ‘Harry Potter and the Sorcerer’s Stone’. The change was made after Arthur Levine from Scholastic stated that he believed the word ‘philosopher’ was too ‘archaic’ for readers and expressed concerns that readers would not relate to the book’s original title. Rowling herself has since said she regretted allowing this change but did not feel she was in a strong enough position to challenge it at the time. Whether the change had a significant effect on readers choosing to buy and read the book is unclear, but the book remains popular on a global level decades after its publication. As of November 2018, close to *********** Goodreads members worldwide included the novel on their ‘to be read’ lists.

Other changes made were of the linguistic nature, to cater for readers used to American English. For the benefit of U.S. readers, the British word ‘mum’, as well as Irish term ‘mam’ used by the character Seamus Finnigan, were changed to ‘mom’. Other words were also changed to suit an American audience, including ‘jumper’ to ‘sweater’, ‘sweets’ to ‘candy’, and ‘windscreen’ to ‘windshield’.

Another change which affected the books and their author on a global level was the creation of Rowling’s pen name. Rather than publishing the books under the name Jo or Joanne Rowling, the author was advised to use initials to disguise her gender in order to appeal to boys as well as girls. It was thought that despite the book being considered suitable and relatable for both genders, that young boys may not choose or relate to a book written by a woman. Years later, favorability of J.K. Rowling among men and women is almost identical.

Harry Potter

British author J.K. Rowling made waves in the children’s book industry upon the release of her debut novel ‘Harry Potter and the Philosopher’s Stone’ in the UK back in 1997 and is now one the most well-known authors in the world. Rowling’s ‘Harry Potter’ books are adored by readers across generations all around the globe, and despite diehard fans having their reservations about the movie adaptations, all the films performed well at the box office.

The first movie was released in 2001, the same year as ‘Lord of the Rings: The Fellowship of the Ring’ – another favorite among fantasy film fans. The Harry Potter movie franchise culminated with the eagerly anticipated adaptations of the ‘Deathly Hallows’ book, with the last film being released almost ten years after ‘Harry Potter and the Sorcerer’s Stone’. As is often the case in the movie industry, the final book was spread over two separate films in order to do justice to its length and detail.

Another common practice in the film industry is to release prequels to already successful movies, creating lengthy billion-dollar franchises. Significant movie franchises with prequels range from ‘Alien’ and ‘The Lord of the Rings’ to ‘X-Men’ and ‘Star Wars’, and the release of ‘Fantastic Beasts and Where To Find Them’ in 2016 marked the first of five planned Harry Potter prequels. These, along with the original Harry Potter movies, collectively make up fictional universe the Wizarding World, which is one of the highest grossing film franchises of all time.
