Harry Potter and The Deathly Hallows, Part 1: Will It Sell Books?

By Maryann Yin Comment

Every time a Harry Potter movie is released, sales for the book series rise. However, according to the Nielsen Company’s research, the movie boost has decreased with each film. In the graphic embedded above, you can see how series book sales have increased in the lead-up to Harry Potter and The Deathly Hallows: Part 1 (click to enlarge).

Nielsen has more details: “During the four weeks following the November 2001 big screen debut of Harry Potter and the Sorcerer’s Stone, sales of the corresponding book more than tripled over the previous four weeks to 956,700 units … The most recent Harry Hollywood incarnation, Harry Potter and the Half-Blood Prince, had a less dramatic effect on the book brand at its July 2009 box office debut. All Harry Potter books saw an uptick in sales but on a lower scale: Half-Blood Prince sold 50,400 units the four weeks following the movie’s debut, compared to the 33,800 books purchased the four weeks prior.”

What do you think? Will the final two films drive more sales this year? Or do all the Harry Potter fans already own all the books? Share your thoughts in the comments.
