For the reasons that I gave above, film and television programming, even when viewed on the same 50" HD screen, are very different experiences.

Anyway, you're missing McLuhan's point, which has to do with the level of engagement--simply stated, "hot" media require that you pay a lot more attention than "cool" media. A symphonic composition is "hot"--you have to pay complete attention from beginning to end in order to fully appreciate it. Mantovani and His Orchestra, on the other hand, are "cool". You don't have to listen very hard to get it--

McLuhan is widely misunderstood--in no small part because he chose labels for his ideas that were catchy, but not very clear. "The medium is the massage" is usually misquoted as "The medium is the message" because "The medium is the massage" has no apparent meaning.

What he intended, though, was that you take massage in the sense of kneading or forming. Translated into language that you and I understand, it would be more like, "The medium shapes the message" which actually seems pretty obvious.
