Tiedonantaja's current editor-in-chief is Petra Packalén[1] who was preceded by Marko Korvela (2012-2018) and Erkki Susi (1983-2012).

Tiedonantaja was founded in 1968 as the paper of the taistoist minority faction of the Communist Party of Finland[2] until the opposition was expelled in the mid-1980s.

[clarification needed] During the 1970s and in the first half of the 1980s Kansan Uutiset represented the moderates in the party whereas Tiedonantaja was the organ of the doctrinaire faction.

Tiedonantaja was first published irregularly by the Uusimaa district organisation of the SKP.

It became a nationwide publication after other taistoist districts joined, and in 1970 the paper began to be published on a weekly basis.
