Skateboarding 2012 Calendar. Skateboarding originated sometime in the 1950’s and coincided with the popularisation of surfing in California, USA. Skateboarding has been shaped and influenced by hundreds of skateboarders throughout the years and a 2002 report into skateboarding found that there were 12.5 million skateboarders in the world. Eighty percent of skateboarders polled who had used a board in the last year were under the age of 18, and 74 percent were male! This Skateboarding 2012 Calendar will make an excellent and inexpensive gift for 2012!
