Nine Decades of the Radio Industry in Brazil

摘要

Seen as a whole, Brazilian radio allows for the identification of six distinct kinds of use: commercial, educational, cultural, communitarian, religious, and political. Subsequent to the educational and cultural broadcasting stations of the 1920s, commercial radios are established as the standard, as from the 1930s. During the trajectory of 9 decades of this means of communication in the country, Cetulio Vargas emerges as the politician who most influenced the national broadcasting industry, with laws and decrees that still apply today and are at the base of technological, legal, and content evolution.
