Porsgrunds Dagblad was started on 1 December 1914, and later modernized its name.

The first editor Daniel H. Grini was an experienced press worker, and came from Varden in the neighboring city.

It bought both Breviksposten in 1916 and later Langesunds Blad and Skiens Dagblad.

[1] It prevailed over Grenmar, which went defunct in 1954,[3] but faced tougher competition from the Skien-based regional newspapers Varden and Telemark Arbeiderblad.

[4] Bjørg Vik and Jahn Otto Johansen started their careers in Porsgrunns Dagblad, and the newspaper also printed feuilletons which later became books by Jon Flatabø and Karen Sundt.
