1990 Philippine Basketball League season

The 1990 season of the Philippine Basketball League (PBL).

New era
Under New Commissioner Andy Jao, the Philippine Amateur Basketball League (PABL) starting the new decade will now serve as a farm league to the Professional Philippine Basketball Association (PBA). The Word "Amateur" was dropped and the league was renamed Philippine Basketball League (PBL).

Rule changes

 * Games were now played under professional rules. the PBL will be playing four quarters of 12 minutes per period, instead of two halves of 20 minutes.
 * The use of two referees, and three free throws awarding a player fouled while attempting from the rainbow territory.
 * Each team is entitled five timeouts instead of four as in the old practice, instead of seven team fouls, six gets the team into penalty situation. Only man defense will be allowed, players fouled during penalty situation will be automatically awarded two free throws, eliminating one-and-one and the right to wave.
 * A unique rule the PBL implemented was the way an extension is decided, instead of a five-minute extra period, winners will be decided by a tie-breaker, awarding victory to the team that first scored seven points in the extension. According to Commissioner Andy Jao, who apparently was inspired by tennis rules on tie-break, this will eliminate multiple extensions that tend to prolong the game.
