It was 1927 in Hawaii, and a new brand of fruit juice called POG was introduced. On top of each bottle was a small round cardboard lid/cap.
The 1930s were the years of the Great Depression, where thousands of people lost their jobs, and had no money to spend on toys. This led to children making their own games, one of which involved the caps from the juice drinks. The idea was to flip the caps, and it became known as POGs. The children drew designs on these caps and made Kinis (slammers) which were 3 caps glued together. Popularity eventually faded. Until Blosson Galbiso, a school teacher who had played POGs growing up with her friends in the 30s introduced the game to her pupils in 91. The game of POGs spread once more. In 93, POGs spread to California, then state after state. National tournaments were organised, and other brands were formed to compete. POGs were then launched in the UK at the beginning of 95, where the craze only lasted a brief year before dying once more.
