Radio evolved with the help of the navy and soon transfered its power to broadcasting companies. What certain companies did was allow installation of various broadcasting networks which hosted paid programming, advertising, news and live music performances. But before any of this was possible, (what was known as) "the amateurs", a select few who could assemble and operate radios, dominated the air-waves. It wasn't until radio regulation acts were passed, that broadcasting became more structured. But the most important factor in public access to the radio was the mass production of radio parts. This was possible thanks to the radio industry and Mr. David Sarnoff.
Sarnoff had a vision: that individual home owners should have access to personal radios of their own. No longer would the air-waves be manipulated by the technologically savvy or the elite. Sarnoff's prediction of revenue after selling these "music boxes" was dramatically exceeded. This was not only a marketing success but a powerful force in the formation of the radio industry. People now enjoyed music, news, politics, ads and dramas in their very own homes. As a result the radio shaped the values and expectations of many Americans. None of this would have been possible without the aid of the radio industry itself.
