In Japan, where baseball is inarguably the leading spectator team sport, combined revenue for the twelve teams in Nippon Professional Baseball (NPB), the body that oversees both the Central and Pacific Leagues, was estimated at $1 billion in 2007. Total NPB attendance for the year was approximately 20 million. While in the preceding two decades, MLB attendance grew by 50 percent and revenue nearly tripled, the comparable NPB figures were stagnant. There are concerns that MLB's growing interest in acquiring star Japanese players will hurt the game in their home country. In Cuba, where baseball is by every reckoning the national sport, the national team overshadows the city and provincial teams that play in the top-level domestic leagues. Revenue figures are not released for the country's amateur system. Similarly, according to one official pronouncement, the sport's governing authority "has never taken into account attendance ... because its greatest interest has always been the development of athletes".
