I came across these three items on YouTube featuring early radio in the state of Ohio... The film is divided into three parts...the last part ends abruptly before a natural ending point. I checked the "Ohio Film " web page and these three parts are the only threads available . So here is a historical look at Ohio radio in the 1930s...enjoy.
Along with each link is a brief description of the contents of the film segment.
OHIO RADIO PART 1 ;
This is the first in a three part film on Ohio broadcasting in the 1930s. From the transmission towers to the on-air talent and sales. It covers The three main cities of Cleveland, Columbus and Cincinnati.
