Radio transformed print media, news, sports, politics, music, home entertainment, education and even the driving experience, and would in turn have to reinvent itself with the advent of TV, satellite, internet and mobile phones. I have had the good fortune of being an RJ in India and in the US, on FM radio (WMUA), satellite radio (Worldspace) and internet (Radiowalla), each with differing strengths in immediacy of user feedback, national reach, breadth of customisable choices, and monetisation.
