amsterdam - Facebook and Twitter celebrate the twentieth anniversary of wizard Harry Potter on Monday. It's June 26th exactly two decades ago that the first book, The Philosopher's Stone, appeared.
Facebook has built an 'easter egg' for the occasion. Who in a message uses the English name of one of the four 'houses' of Zweinstein schools, surprises what magical effects are. Also the name is printed directly in the color of the house: Gryffindor is red, Slytherin green, Ravenclaw blue and Hufflepuff orange.
Twitter has created the special # HarryPotter20 emoji in collaboration with Pottermore and Bloomsbury. Fans can easily get started with the new emoji. Using the hashtag # HarryPotter20, Harry's iconic scar and glasses appear in the tweet.
Writer J. K. Rowling completed the script in 1995 and tried to wear a publishing house for two years. Eventually Bloomsbury went over; The first edition of the book was only five hundred copies. In the meantime, nearly 500 million copies of the seven Potter books have been sold.
