Reading the excerpt from Marshall McLuhan’s book called “ Understanding Media: The Extensions of Man” talks about how media has changed humans lives, not the content of it but the medium. 

In the reading,McLuhan sees that media is communicating its own importance and that content once in a while has a genuine impact on individuals, though the medium has solid impact. Humans especially nowadays rely on the media so much that it became part of their life. For instance, your arm is an extension to your body; it is a part of you and you rely on it for daily needs and purposes. We use our arms and hands to use different tools like using a spoon to eat. The spoon also becomes an extension. This broadens our abilities beyond what we can physically. With technology/media there is virtually no limit to how far humans can extend. 

McLuhan famous line from the book states “ The Medium is the Message”. What it basically means is that the medium through which we decide to exchange information holds as much, if not more, worth than the message itself. It is really not the content that is important but it is how we give and receive the content that makes quite the impact. McLuhan believes technology to be the extension of humans, like I mentioned above humans rely on the internet quite a lot even designers. For a designer, the most powerful medium is the internet. For them to design and pass on the message they want convey, is through the internet and internet is the designer’s extension.
