Hacky Sack
From Wikipedia, the free encyclopedia
Hacky Sack is the trademarked name of a type of footbag. The name "hacky sack" came from the inventors of the footbag, Marc Vuolo, John Stalberger and Mike Marshall from their home town, Hackensack, New Jersey.[1] Although Marshall suffered a fatal heart attack in 1975, Stalberger continued the business.[1] At a later date, Stalberger sold the title to Wham-O. The name Hacky Sack has become a genericized trademark, and can refer to either the footbag or a footbag game. The classic hacky sack circle consists of two or more players that keep the footbag off the ground without using their hands. Some common tricks include, stalls, bag daggers, lifts, loops, ham spalts, and milk tossess.
The idea of the game is similar to traditional Asian games of kicking the shuttlecock, known as Jianzi and Chapteh. In Korea it is called Jae gi cha gi. The game is also similar to some South East Asian games, such as Sepak Takraw and Sipa.

Wham-O maintains the validity of its trademark through not only keeping the registration updated at the U.S. Patent and Trademark Office but through reporting infringing importers to U.S. Customs, and filing trademark infringement actions in Federal Court.
