First of all I recommend anyone reading this (especially Ken Burns) to pick up a copy of "Tesla" by Tad Wise. Tesla is one of the most brilliant and fascinating inventors of all time.
Without Tesla we would not have radio! We would also not have television, alternating current, electric motors, fluorescent light, remote controls and the list goes on and on. He has around 300 patents and phony Marconi infringed on more than one. But he's not the only one to cheat Tesla, give Thomas Edison and George Westinghouse their due.
So what happened Ken Burns? Were you getting your funding from Republicans that forced you to manipulate history? Wasn't Tesla enough of a money grubbing cheating capitalist for you? Well you lost a lot of credibility with this and it's a shame.
I suggest you change the title slightly. Let's call this pretend documentary, "The Men Who Made-Off With Radio"
To think that children trying to learn about the history of radio may as a result of your abomination never hear the name Nikola Tesla. This reflects so poorly on PBS and Ken Burns the thing should be retracted. At the very least Ken should appear at the beginning of the film apologizing and saying we really blew it with this one. We didn't do our research on something as basic as who invented radio.
