From NPPL.tv:
"The NPPL is the National Professional Paintball League, the sole sanctioning body for all amateur and professional paintball players in North America. It is a league, where player representatives
formulate league rules, make business decisions and
sanction and
preside over all aspects of any NPPL event. The NPPL was founded in 1993 and is the oldest such organization."
