Sometimes these three men were friends … At other times, they were cutthroat business rivals
The filmmaker 
Ken Burns became famous when 
“The Civil War” came out in 1990. At the time I write this, 
“The Civil War” is still the most popular program ever shown on 
PBS. But few today know about another program that he later made, which came out in 1992. The film that I refer to is, of course, the film “Empire of the Air: The Men Who Made Radio.” Although the subject is a bit obscure, it’s actually much more interesting than one might assume from this fact. It’s a biography of three different men (all very interesting), who helped to create the industry of radio. They were pioneers in the invention of a new information and entertainment medium. Some of them were even friends and colleagues with each other in earlier years, but some of them were cutthroat business rivals and bitter enemies later on. This film is thus a bit like doing twin biographies of 
Ulysses S. Grant and 
Robert E. Lee, as 
Ken Burns does in 
“The Civil War.” But with one exception, no one died in this market competition between these three businessmen; although that doesn’t make it any less dramatic. (The person who 
did die, incidentally, was one of these three men – I shall not say which one – when he jumped out of a 
New York City window to fall 13 stories to his death. This suicide was brought on by his being beaten at the 
game of business, and thus driven to some amount of poverty and ruin.)
