[Solved] Technology Caused Changes

The new technologies of the 1970s allowed listeners more personal choice in what they listened to at home and in their cars. Later, people gained even more freedom when they could listen in their portable headphones when they listened to their SONY Walkman. This change in technology caused changes on the radio as well, where we see the advent of Album Oriented Radio (AOR). What were the pros and cons of AOR? How did the AOR movement narrow the role of the DJ on the radio? How did this change the power structure within the music industry? Do you believe this was positive or negative for the music world and why? 

In response to at least three of your peers, consider an album that was either positively or negatively affected by AOR. Does this album’s success or failure confirm or deny your peers’ viewpoints?
