- IDEA 1 OF 8
The medium matters more than content
McLuhan argues that the form of a medium, such as print, radio or television, has deeper effects on society than the content it carries.
He summed this up in his famous slogan about the medium and the message.
- IDEA 2 OF 8
Media extend our bodies
McLuhan describes media and technologies as extensions of human senses and abilities.
The wheel extends the foot, and electric media extend the nervous system. On this view, each new medium reaches further than the human body could by itself.
- IDEA 3 OF 8
Media can be hot or cool
McLuhan divides media into hot, which give lots of detail and need little participation, and cool, which need more audience involvement.
In his scheme, a lecture asks little of the audience, while a conversation asks much more.
- IDEA 4 OF 8
The world is a village
McLuhan argues that electric media connect people across the world, creating a global village.
Distance matters less. People everywhere can see and hear the same events almost at once, which brings them closer in experience.
- IDEA 5 OF 8
Print shaped linear thought
McLuhan argues that printed books encouraged linear, step-by-step thinking and individualism.
Reading line by line trains the mind to order thoughts in sequence. He believed this habit shaped the way people saw themselves as separate individuals.
- IDEA 6 OF 8
Electric media change thinking
McLuhan argues that electric media bring everything together at once, encouraging different ways of thinking.
Instead of one thing after another, people receive many signals together, and this changes habits of attention and feeling.
- IDEA 7 OF 8
We do not notice effects
McLuhan argues that people become numb to how media change them.
Understanding requires stepping back. Because the effects are quiet and gradual, we focus on the content and miss the deeper shift in our habits.
- IDEA 8 OF 8
Television involves viewers
McLuhan describes television as a cool medium that draws viewers in.
He thought it would reshape society. Its low-detail picture asks the audience to fill in the gaps, which makes watching a more involved experience.
