Gaga is most commonly believed to have been brought to North America when the Israeli counselors eventually landed at the Jewish camps in the US. Some Israelis that were staff members at this camp brought this game back to their native country, where it took on the name gaga (www.sportresourcegroup.com).
Regardless of who invented the game, gaga ball has become a popular attraction at numerous schools and camps and it is likely that it will continue growing in popularity.
