I think most here are old enough to recall how the invention and spread of the Internet changed their world. Many grew up with TV and radio and took it for granted. But it's interesting to cast your mind back to the 1930s and wonder what people back then thought about the widespread adoption of another game changing innovation - radio itself. 

It was an expensive miracle for many. And like the web, it did change lives. A new book in England, based on the work of two researchers in the 30s,  gives a glimpse of what happened to society when this "wireless" started turning up in people's homes for the very first time. 

"These included radio’s effects on a man who was once drunk and abusive (“his wife used to tremble when he came home at night, but now he never goes out on Saturday nights even… he used to keep pigeons, now he breeds canaries”), a Welsh grocer obsessed with the news (“I’ve even neglected the bacon machine”) and a husband who tunes the radio to foreign-language stations when he leaves for work, so his wife can’t understand it, then disconnects it completely when he goes away for a conference. “She’s left him now,” trills the interviewee on this subject."
