‘Harry Potter’ turns 15: A look at the series by the numbers

It's hard to believe that 15 years ago today, J.K. Rowling first introduced us muggles to Hogwarts with the release of “Harry Potter and the Philosopher’s Stone,” the first installment of what would become the best-selling series in literary history. The book became an instant hit, selling millions of copies and lighting the torch on a cultural phenomenon that would sweep the globe.

It will no doubt be a proud day for Rowling. So to help her celebrate, why not join us as we look back on her legacy with our “Harry Potter” stat attack.
