Introduction The next two articles explore and analyze the maturity of radio growth over the years and the various situations that may occur during radio development, not the rich atmosphere of the Great Depression. Discussing the evolution of radio in the 1920s from the 1940s to the present reflects major changes. Radio was an important lifeline of mass information during World War II.
In Africa, according to the Africa Media Development Initiative (AMDI) report, remarkable growth has been seen in the radio industry over the past 20 years (AMDI 2006). These increases come from community broadcasts and commercial radios. Commercial radio is in major cities and towns, community radio dominates rural areas. Sterling et al. According to "In the past 20 years, the number of community radio stations in sub-Saharan Africa increased to more than 10 to 800" (Sterling et al., 2007). This will make community radio the most effective means of communication in rural areas of Africa. According to Sibanda, the number of listeners in sub-Saharan Africa is estimated to reach 91.1% (Sibanda 2001; Sterling et al. 2007). The women's ownership rate of the station is estimated to be 67.8%
Independent radio stations can be divided into five types. We are looking for profitable commercial radio stations, religious radio stations - most of these radio stations are supported by sponsors, and development of commercial radio stations supports weak points of many countries supporting talented artists It may change. They do better by selling their own music on stalls. Regional radiation stations can be regarded as the fastest growing sector - these sites are often supported by volunteers, low cost operations and external sponsorship. By 2000, there were over 70 radio stations in South Africa and over 100 radio stations in West Africa. The fourth and fifth categories are the result of race and other struggles. Faction radio stations are used to promote certain parts of the struggle. This category is also known as Hate Radio. (Myers, 2008)
