Rowling’s “Harry Potter and the Philosopher’s Stone” (later renamed “the Sorcerer’s Stone” in America) was released on June 26th, 1997.

To commemorate the 20th anniversary, Facebook added a neat animation to its web and app platforms.

Any statuses or posts with the words “Harry Potter,” “Gryffindor,” “Slytherin,” “Hufflepuff” or “Ravenclaw” (or with character names such as “Draco Malfoy”) show up in bold and in their respective house colors on Facebook.

If users tap on any of the key terms, a wand appears out of nowhere and shoots out sparks as if to cast a spell.
