&nbsp;&nbsp; 8ª ano

A ERA DO RÁDIO

Rádio é um veiculo de comunicação essencialmente auditiva, baseada
na emissão, difusão de informações sonoras, por meio das ondas de rádio, em
várias freqüências. 

1ª emissora de rádio: KDKA, em novembro de 1920, nos Estados
Unidos.

1924 – “Era do rádio”

A era do rádio brasileira

1ª transmissão: aconteceu durante
os festejos do Centenário da Independência, em 1922. Foram ouvidos o discurso
do então presidente da republica, Epitácio Pessoa, e trechos da opera O
Guarany. Com muitos ruídos, imaginando que não passava de um truque.

Finalidade: &nbsp;cultural e
educativa. Os anúncios pagos eram proibidos, a radio era mantida pelas doações
de seus ouvintes.

1930- surge a rádio comercial, passando a ser popular.

Músicos: Francisco Alves e Carmem Miranda,Silvio Caldas, Vicente
Celestino, Orlando Silva, Emilinha Borba e Ângela Maria.

Os interesses dos proprietários
passaram de educativo para mercantis.

A rádio tornou-se, grande instrumento político. 

Passou a ser além de veiculo de comunicação de massa instantânea,
uma forma de alfabetizar, de pedir voto de certa maneira de manipular seus
ouvintes.

Revistas especializadas em rádio:
Radiolândia e a Revista do Rádio.

Década de 40: Época de Ouro do rádio brasileiro – surge o radio
jornalismo

1947- invenção do transitor: transmissão “ao vivo”.

1950 – Era do Rádio. Mais tarde com o advento da televisão os
artistas do rádio migram para a TV.

1960- rádios de freqüência modulada(FMs).

1990- rede Bandeirantes torna-se a primeira emissora no Brasil a
transmitir via satélite. 

2005- O rádio ressuscita: transmissões analógicas e digital. &nbsp;
