, a part of Tribun Network In the late 1980s, the Department of Information asked major newspapers to assist minor local newspapers that were hampered by press permit (SIUPP) issues. The government restricted advertising space to 30% of all content for newspapers not aiding minor newspapers. In 1987, Kompas Gramedia acquired the
Sriwijaya Post in Palembang and established the subsidiary PT Indopersda Primamedia (Persda) to assist regional newspapers in need. In 1988, the company acquired
Mimbar Swadaya, a weekly newspaper in Banda Aceh—rebranding it as
Serambi Indonesia—and
Surya, a weekly newspaper in Surabaya that began publishing daily. Kompas Gramedia acquired the daily
Pos Kupang in 1992 and the
Banjarmasin Post in 1994. Persda later strengthened its business by publishing its own regional newspapers in other cities under the
Tribun brand. The first newspaper to hold the brand,
Tribun Kaltim, was published in Balikpapan in 2003, followed by
Tribun Timur (Makassar) and
Tribun Jabar (Bandung), among others. In 2010, Persda rebranded as Tribun Network and launched the unified online portal Tribunnews.com. In 2014, Tribun Network published a nationally oriented sports newspaper,
Super Ball, as a spin-off of the football sections of its members' newspapers. Its online portal, which was originally a subdomain of Tribunnews.com, is currently a subdomain of
Bolasport.com. == List of newspapers ==
