The first three came in one day. Now we’re working 
on Understanding Media  and the subtitle is The  
Extensions of Man . So one general statement is, 
“Every technology, every innovation, amplifies or 
enlarges or extends or enhances—blows up in 
some way—something that is already there.” You 
take something that’s already present and you 
enlarge it with this new technology or technique. 
So, motorcars, for example, let you go faster than 
horses do. Airplanes let you go considerably 
faster, and farther, and so on. Every new 
innovation extends or amplifies or does something 
with human experience, it opens it up in a new way.
