60 minutes = 5000 years that people have had access to writing systems
On this scale, there were few significant media changes until about 7.5 mins ago -printing press came into use in Western culture.
2 minutes ago - - - the telegraph, photograph, and locomotive
1.5 minutes ago - - - telephone, phonograph, rotary press, motion pictures, automobile, airplane and radio
1 minute ago - - - talking picture
In the last 40 seconds - - - the TV
In the last 6 sec - - - the computer
Last few - satellites, laser beams, translation machines, interactive telecommunications, Internet, video games
We're always playing catch-up...
