The magazine was first published on 1 April 1971, being founded by Barend Toet.
Originally, OOR was published as a newspaper, hence the word 'krant' in the name. From the 1980s onward, the word Muziekkrant was dropped from the title and OOR had become a magazine. Around 2005, also the frequency changed. Originally a bi-weekly publication, OOR is now a glossy monthly.
