This research deals with the Economic Policy of Communication, which dialogues with studies about cultural industry (ADORNO, HORKHEIMER, BOLAÑO, MAURÍCIO, BENJAMIN). In this context the work goes through an analysis about Radio Globo s sinking. Radio Globo is an important brazilian radio station, which went through a radical schedule grid transformance after more than seventy years of existance. This radical change was based on the will to aim a new target audience. Radio Globo despised the listeners who susteined its existance for decades. This route change brought some new features classified in this dissertation as a radio gentrification, once it excludes old and poor people. The solution to avoid decisions based only on economic strategies would be a public financing model. This should ensure plural and democratic access to the disclosed contents. In many cases this gentrification is shown as digital exclusion and also a complementary exclusion of the consumer society.
