The VPRO (originally an acronym for Vrijzinnig Protestantse Radio Omroep, or "Liberal Protestant Radio Broadcasting Corporation") was established in the Netherlands in 1926 as a religious broadcasting organization. Falling under the Protestant pillar, it represented the Liberal Protestant current. However, in the 1950s and 1960s it became more (social) liberal than protestant, and while the acronym VPRO was kept, its meaning was dropped.
