Hot or cold

Hot or Cold?

These slides show a progression of communication methods for mankind over the millennium.

Most who are reading this know the history well since 1994, when this history account ends. Surely, things have gotten faster, better from the perspective of this writer. In the final analysis, cold and hot are relative terms…what one finds cold, well, another does NOT!


Who predicted what

Who predicted what?

As slide 8 points out, the internet was born, alive and kicking, when

McLuhan WAS still around, alive and kicking. Much of what he has written, in his style, was likely common knowledge to many who worked and operated with certain sectors of the American Government in HIS day!

It is important to give credit where and when it is due…and important not to give it when it is not!

Hot and cold is so relative!
