Great video, Matthew and Gladius!
Yes, all the rot came via different media. The Canadian Catholic philosopher Matthew McLuhan said, "the medium is the message."
As the technology of the media gets more advanced our cognition, as he pointed out, gets affected.
Let's start with ancient and medieval times. The mind of both the producer and reader were engaged in the materials used to spread information. Then came the printing press during the Renaissance. It was cheaper by comparison to what came before, but the risk was a too rapid dissemination of ideas. Hence, the Protestant revolt.
Later on, industrialization and the telegraph made it easier to make it too convenient to spread information to foster immoral political strategies and maneuvers.
Then comes the telephone. Peace and quiet are more at risk to be disturbed.
Motion pictures are developed and can give cause for distortion of the imagination. The phonograph and radio could have done the same thing but not as much due to the lack of visuals.
The television then arrives, making distraction for frequent and accessible.
The internet then in turn with its usage on computers and cellphones tops them all with constant distraction and disturbance of the mind.
