Why was radio important? How do you know this?

Radio broadcasts can provide real-time information, broadcasted 24 hours a day to provide the most recent updates to listeners. Stations have the ability to reach across borders and become a source of information where reliable news is scarce. When access to the internet is blocked and phone lines are cut, people can still search the airwaves for trustworthy sources. Even electricity is not a necessity for battery operated and hand-cranked radios.

Radio is about companionship and the emotional connection with the listener. Radio broadcasts provide real-time information, and some that broadcast 24 hours a day, can provide the most recent updates to listeners ... Radio is not just important for reception of emergency announcements and communications during disasters.
