Guns or Microphones
The BBC has a program called Revolutionary Radio. The teaser for the current episode says "A revolutionary General in Nicaragua asks what is more dangerous in the hands of the public, guns or microphones?"
This is a one hour radio program that documents how radio has played a part in many revolutions. It includes a lot of audio history of the use of radio starting in the first half of the 20th century. The program shows how radio was the tool but makes the point that it really was the use of new technology and that Facebook and Twitter are really just another new technology. The reality, at least in Nicaragua today, is that while tweets will speak to some, radio remains the best tool to reach the masses.
The history is interesting. Today, how we on the information has changed or at least been augmented by other communications methods but the concept has not. Basically, it is either marketing or propaganda, depending on which site you were on. You can listen the program on the BBC web site.
Over the past 90 years radio has proven itself a powerful political force, not just reporting on changes of government, but sending out a call to arms during some of the biggest revolutionary uprisings of the 20th Century. These events track radio's evolution, from its rise as an exciting new technology used by the Bolsheviks to demonstrate their modernity, to its reported demise amid the social media buzz of the Arab Spring.
