Notable occurrences
The NBN/IBC consortium took over the league's TV coverage after winning the TV rights over the league's longtime TV partner Vintage Television in December 2002.
Noli Eala became the league's sixth commissioner after Jun Bernardino retired at the end of the 2002 season.
The league reintroduced the Invitational Championship and the Reinforced Conference.
The league reverted their rules of playing 12-minute quarters and the use of the 6.75 m (22.1 feet) three point line. The eight-second backcourt rule was retained. In 2002, the league adopted all of the FIBA basketball rules to prepare the players that will play for the Asian Games in Busan.
The league's greatest rivalry; the Crispa Redmanizers and Toyota Tamaraws clash in a reunion game coinciding the league's All-Star Weekend at the Araneta Coliseum. The Toyota Tamaraws won, 65-61.
The NBN/IBC consortium and the PBA contested the placement of logos of Beam Toothpaste at the Araneta Coliseum's basketball flooring. The advertisement placements were done between the Araneta Coliseum and Nelson Macaraig's Jonels Promotion. A same agreement was done by Jonels Promotion for the PhilSports Arena. The league considered this as "backdoor advertising" as Macaraig did not enter an agreement with the PBA to put Beam's logos in the league's main playing venues and threatened the management of both venues that they will not hold their games at Araneta Coliseum and PhilSports Arena unless both will remove the Beam Toothpaste advertisements.
