A characteristic feature of the North Rhine-Westphalian local broadcasting concept is the so-called two-pillar model. In addition to the material program requirements, there is a special attempt at structural control through organizational and procedural measures at the local level, aimed at ensuring program diversity. This report is the final report of a research project on the effects of these organizational and procedural diversity safeguards during the establishment phase of local radio programs in North Rhine-Westphalia. The project was commissioned in late 1989 by the State Institute for Broadcasting in North Rhine-Westphalia. The Hans Bredow Institute for Broadcasting and Television independently carried out the project and completed it in December 1991. The project was conducted under the responsibility of the institute's director, Professor Hoffmann-Riem.
