I almost didn't post this because the book itself doesn't seem really worth reading but in the end the concept put it over - a book on television from 1932! Well, maybe not that big a concept and with the book's mentions of color TV and kinescopes I almost thought it was a prank of some kind. But Dunlap was a New York Times reporter with other works on radio and Marconi and apparently my local academic library has a physical copy. Just wish it had more illustrations.
