uncle charlie
Uncle charlies were a big thing cause this means that alot of people can have there own radio station in there home. This was good and bad good is that alot of people could be in the radio industry but the bad part was that everyone had so radio advertisment was hard because of the same radio frequency. What they did was that you have to ask the fca at the time and each person gets a different frequency in a certain area of eachother. -
The amplifier
The audion is a tube to amplify signals like a guitar amp, amplifying sound. The invention was borrowed by Lee de forest but it was beleived that a canadian inventor, Reginald Fessenden but he did not get the credit for it. The affect of this is that our radios only provide 100 watts of power and imagine the subwoofer system in cars thank to amps it supported more wattage to power it. -
Why music for the radio industry?
Music was good a lot of people like music right but how would we enjoy it? We'll we just can't whip out our phones and go to iTunes or pandora we would have to go to a diner or a restaurants to listen to a juke box or a home record. And that was inconvenient so music aired on radios which saved them from dying out. -

The FRC
Uncle charlies were a big hit but how would the commercials get customers nor money to the radio stations? The government established the FRC "federal radio commission" and what there job was, to limit the radio stations in a certain area with the certain frequency. So what you had to do is to go to the FRC to ask permission to get the certain frequency fm or am so you won't enterfere with other radio stations. -

Why was talk and music splitted?
The reason for am and fm to be differed cause of the wave length and as we know fm frequancy's are more close and compacted and bigger wave which gave a more clear sound in music. Am was more spaced out and it was ideal for talk and less on music. Reasoning for that is cause music has a bigger affect on the sound with the high's, mid's, and low's and that's why fm is more based on music. -
