Membership-based Dutch broadcast groups The following are the eight major Dutch broadcasting groups. All broadcast on both radio and television. (Some organizations have only radio in the title, because they were named before TV existed.) Dates each organization began broadcasting and the size of the membership as of January 1, 1982, are given. A groups (more than 450,000 members) AVRO (Algemeene Vereniging 'Radio Omroep,' General Radio Broadcasting Association) Jan. 1, 1928. 809,847. Tries to be general in its program content. The chairman is a well-known member of the right-wing Liberal party, to which some 40 percent of AVRO's members belong. TROS (Televisie Radio Omroep Stichting, Television/Radio Broadcasting Foundation) Oct. 2, 1966. 763,177. Began, for a few months in 1964, as Radio/TV Noordzee, a pirate station.

KRO (Katholieke Radio Omroep, Catholic Radio Society) Nov. 24, 1925. 611,254. More liberal than the Netherland Roman Catholic Church at large, but not so liberal as to offend the bishops.

C groups (more than 150,000 members) EO (Evangelische Omroep, Evangelistic Broadcasting) April 1, 1970. 227,000. Formed by those who believed NCRV's programming to be too secular.
