The co-operative kicking sport has ancient origins from China, Thailand, Native America and nearly every country. Hacky Sack or Footbag, as we know it today, is a modern American sport invented in 1972, by John Stalberger and Mike Marshall of Oregon City, Oregon. Marshall had created a hand-made bean bag, that he was kicking around. Stalberger was recovering from knee surgery and was looking for a fun way to exercise his knees. Together, they called the new game “Hackin’ the Sack.” The two decided to collaborate and market their new game under the trademark of “Hacky Sack®”.
