The “medium is the message” demonstrate how modern media reflect human senses. This interpretation gives us a new approach of reading the history. Considering tools as medium, let us understand the details of the family life style of an ancient family. It is an enjoyable way of thinking about history. On the other hand, Benjamin says: “that which withers in the age of mechanical reproduction is the aura of the work of art”. Considering these two facts together, shows that this ability of reading the history through the medium is changing. If a sword of a soldier had been made by an ironsmith, now the rockets are being made by the technologies. The first one is about the taste and manner of the ironsmith and his time, but the second one is only talking about our time not the workers who are working in the manufactury. McLuhan emphasizes most on the importance of the medium than its content. In my opinion, medium has a second role in both aspects which was not formed in his age as powerful as today. This second role is the hidden action. When the medium’s message is different than its appearance. Because today’s mediums are more complex than before. When a lamp is talking about light and changing lifestyles through lighting, an energy efficient lamp is also talking about our contemporary crisis of energy. Consequently, nowadays, there is a complex graph of forces in both inventing and using a medium.
