Communication biases and Monopolies power

I came over an article by Harold Adams Innis, a political economist, whose famous for his communication theory in Marshall McLuhan.
In this article, he discussed about the common errors in communication biased, and i think it may help us in avoiding message receive and sent wrongfully.
He mainly discussed the communication biases through three aspects:
"1. How do specific communication technologies operate?
2. What assumptions do they take from and contribute to society?
3. What forms of power do they encourage? "
