Oh, I know. I wrote a paper on the rise of radio in 1920s America when I was wrapping up my history major. It wasn't an American invention and the man credited with "inventing" radio wasn't American, but given Prager U's penchant for distorting history to make it more "patriotic" I wouldn't put it past them to downplay the likes of James Clerk Maxwell, Heinrich Hertz, Oliver Lodge, Jagadish Chandra Bose and even Marconi while boosting Reginald Fessesnden's role (even though he was born in Canada)."Radio's invention" is a good example of "Success has many fathers; failure is an orphan."
To even try to credit one person for the "invention" of radio is futile. There are so many contributors to the point of a radio signal being sent and received that it would fill a good portion of a "History of Radio" collection.
Prager U is just the worst. Over-simplified "history" that's often wildly inaccurate due to the bias of Mr. Prager.
