[Stephen posted a link](http://www.downes.ca/post/53972/rd) to [this newly rediscovered video](http://www.brainpickings.org/index.php/2010/03/15/marshall-mcluhan-global-village/) of [Marshall McLuhan](http://www.marshallmcluhan.com/) discussing media on [CBC’s Explorations documentary series in 1960](http://archives.cbc.ca/programs/241/). This was 4 years before [Understanding Media](http://en.wikipedia.org/wiki/Understanding_Media) was published. It’s well worth watching. It strikes me that this kind of deep, theoretical presentation/discussion would likely be impossible to broadcast now.
**UPDATE:** As of October 27, 2010, the video was taken down from YouTube, due to a copyright violation claim by CBC. I suppose they’re planning to rebroadcast the 50 year old video at some point?
I’m sure McLuhan would have something to say about the message of copyright takedowns and the ephemeral nature of corporate digital media.

on the format of newspapers, and the effect on perception:
>The position and size of articles on the front page is determined by interest and importance, not content. Unrelated reports… are juxtaposed; time and space are destroyed and the *here* and *now* are presented as a single Gestalt. … Such a format lends itself to simultaneity, not chronology or lineality. Items abstracted from a total situation are not arranged in causal sequence, but presented in association, as raw experience.
on communication channels:
>Thus each communication channel codifies reality differently and thereby influences, to a surprising degree, the content of the message communicated.
**DN:** both concepts apply nicely to educational technology, and to online discussion. How does the format of the online discussion platform shape the presentation, perception, and shape of the message(s) communicated?
