Over the decades, the perception of the individual has shifted. This can be seen in the technologies that we use. For instance, in the past, more people relied on mass transit systems to get around. This meant that people were at the mercy of the schedule and routes of mass transit. If we shift the same thought to media, radio was the commonly accepted way to listen to music. However in that category, if you wanted to listen to a specific song, you needed to wait until it was played.
In this modern age, we've learned how to adapt technology to provide us with comfort and ease of movement. Personal cars allow us to go from point A to point B at our own leisure. The introduction of personalized CDs, iPods and MP3 players allow us to listen to what we want, when we want.
The bottom line is that the world where we were small and insignificant is gone. We no longer revolve around our world, it revolves around us.
