Angleball is a registered sports fitness organization and patented equipment manufacturer for North America's oldest sport, anejodi. Angleball's anejodi rules were reestablished as an American tradition during World War 2 at Brown University by collegiate Hall of Fame football and basketball coach Charles "Rip" Engle (March 26, 1906 – March 7, 1983) to keep American World War 2 servicemen fit prior to deployment. Angleball equipment is currently played by 1,000,000+ people in the United States and worldwide and for conditioning in the NFL and by Team USA Olympic athletes. Since 2014, Angleball has inspired a recurring game-type in the world's best selling video game series, Call of Duty, called Uplink. International Angleball has 13 current member countries. The Angleball organization honors its ancient heritage by encouraging groups to produce their own anejodi equipment to Angleball's patented measurements, using available or natural materials, as long as the equipment is not sold. Angleball is a registered trademark and is sold exclusively by the Angleball company.
