In terms of broadcast technologies, which was seen as more revolutionary for its time: television or radio? How was each technology utilized in terms of its intended purpose and audience/users in its earliest years? And were telecom companies its earliest providers, presumably having already provided telephone services and telegraph long before that?
Also, was the invention of broadcast technologies seen as a surprising and significant development from prior point-to-point communications like telegraph and the telephone, or was it more of an expected logical progression from those precursor technologies?
Lastly, many communication technologies seemed to be developed for government or military purposes first and only later considered for public use. Was the same the case for either radio or television?
I'm trying to get a feel for how it impacted the societies in the era they were each invented, including early adoption and enthusiasm surrounding their use.
