Friendship day was originally founded by Hallmark in 1919. It was intended to be a day for people to celebrate their friendship by sending eachother cards, but by 1940 the market had dried up, and eventually it died out completely. However, in 1998 Winnie the Pooh was named the world’s Ambassador of Friendship at the United Nations (believe it or not!), and in April 2011 the United Nations officially recognised 30th July as International Friendship Day.
