Is Reading a Hot or Cold Medium? A Parent’s Guide Through McLuhan’s Lens


Famous Canadian thinker Marshall McLuhan had an interesting way of looking at how different types of media shape the way we see the world. He divided media into two types: “hot” and “cool.”


“Hot” media, like photographs and movies, are rich in detail and fully immersive. “Cool” media, like TV shows or cartoons, leave more to the imagination and invite participation.


When we think about children’s reading through this lens, it gives us some fascinating insights. Even though traditional books might seem “hot,” reading for kids often breaks the mold. Shared reading, picture books, and interactive storytelling make books much more dynamic and engaging than McLuhan might have imagined.


Understanding Hot and cold


  • Hot media are high-definition, offering abundant information and requiring minimal effort from the audience. They fully engage one sense and leave little to the imagination. Examples include film, radio, and printed newspapers.

  • Cool media are low-definition and provide less information. They require more participation from the audience to fill in the gaps, inviting interpretation, imagination, and interaction. Examples include comic books, cartoons, and telephone conversations.


What About Children’s Books?


  • Picture books with rich illustrations: These are more hot, in McLuhan’s terms. Images convey a high level of detail and information, guiding the child’s understanding with minimal effort. The child absorbs both visual and narrative cues, leaving less for imagination.

  • Text-heavy books or early chapter books: These lean toward cold media. Children must actively construct meaning from text, interpret characters’ feelings, and imagine settings and actions. The book provides cues, but the child’s mind fills in the gaps, making reading an interactive, participatory process.

Big Picture


By understanding reading through McLuhan’s dichotomy parents, educators, and designers of children’s media can recognize how books can shape engagement, imagination, and cognitive development. Cold media push children to think critically, imagine worlds, and interpret narratives, while hot media can quickly convey information and captivate attention. The most effective children’s books often balance both, nurturing literacy and creativity simultaneously.


Collectively, children’s reading cannot be labeled strictly as hot or cold because it exists on a spectrum. Hot and cold are relative to each other and will change with the progress of technology. Picture books and graphic novels may lean hot, text-driven stories lean cold, and many books fall somewhere in between. The magic of reading lies in this balance: the interplay between what is given and what the child must imagine.
