Throughout the TML's history, all four teams were directly owned and managed by the Naluwan Corporation, a subsidiary of the TVBS media group, both of which were then chaired by Chiu Fu-sheng.

Chen later decided to join forces with Chiu and turned the Sampo Giants into Taipei Gida, and sponsored this team until the end of 2000, when he realized there was no possibility for the TML to make a profit.

TML's first historical game was played by the visiting Taipei Gida and Chiayi-Tainan Luka at Chiayi County Baseball Stadium on February 28, 1997.

President Chen Shui-bian, who acted as the middle person in the merger agreement, asked First Financial Holdings to purchase one of the teams, while Macoto Bank voluntarily took over the other.

In 2004, Macoto Bank and La New Corporation, who purchased the team from First Financial Holdings, gave in to CPBL demands and paid the fine by adding extra restrictions in these players' contracts.
