After the success of the magazine Intisari (released 17 August 1963), P. K. Ojong and Jakob Oetama launched a national newspaper called Kompas. The newspaper's first issue was released on 28 June 1965.

Their aim was to fill some of the huge gaps in daily news and information that existed at that time. Kompas has since become a large circulation newspaper with an audited circulation in 2005 of 600,000 copies a day. As the largest media company in Indonesia, the KGG operates the largest network printing service in Indonesia.

As of 2018, all media units of Kompas Gramedia is reorganized into one subsidiary, called KG Media.

PT Kompas Media Nusantara published Kompas, the national daily newspaper. Kompas began its first issue on 28 June 1965. Since 1969, Kompas has dominated sales nationwide. As of 2013, Kompas had an average circulation of 500,000 copies per day, reaching an average of 1,850,000 people per day.

Warta Kota began publication after the Ministry of Information under the B.J. Habibie administration relaxed the procedures for applying for a business license (SIUPP) for print media. Indonesia's national newspaper, Kompas (a subsidiary of KG), up until 1998, had designated only two pages per issue for news in Jakarta and its surroundings which were mostly filled with advertisements, even though the newspaper was published in Jakarta. To fill this void, Warta Kota was created. Warta Kota was first published on May 3, 1999, amid the 1999 general election campaign.
