“I came up with the term Mediacracy, but then I learned someone else had the same idea a few years earlier.”
I believe that person was me with the term, “Mediacrat.” IIRC, that term was added to the FR Lexicon.
The term Mediacracy was first coined by Kevin Phillips in 1974, as part of the title of his book, Mediacracy: American Parties and Politics in the Communications Age.
That was at least 20 years before I thought of it.
Prescient.
