Behind the scenes

 * 2011: J.K. Rowling, as a teaser for a mystery announcement, launches a challenge: finding letters, using ten coordinates being revealed among ten Harry Potter fan sites, to piece together a word with the subject of her announcement. A while after all letters are revealed (E-T-O-T-O-P-E-R-R-M), Pottermore.com is launched.
