My biggest take away from the Podcast and The Medium and Message was that the way people are communicating is changing more rapidly then before and the new media is allowing this happen more efficiently. Like it said on the radio show new media is helping to relationship between audience/user and people who want to communicate. If I want to explain this communication with an example of from my field; for a company it is very important to communicate with its costumers. Now these days the company could create a Facebook page under the name of its new product to get a feed back on that product directly from the individual.
Example of such an unrelated event happened when the iPhone came out for the fist time. People were so happy about the product there were discussion rooms about the product all over the internet.
I was aware of new media technologies impacting on my field when I was designing cart like product. Instead of designing wheels I was able to download pre-designed wheels from a website. That saved me some time on completion of my design product.
