What's the long-term prognosis for the health of radio? Depending on who you ask, radio is either a dying industry or an unshakable cultural force. Thanks to its ubiquity, especially in cars, radio remains a medium with gobsmacking reach: 271 million Americans, or 93 percent of the country, tune in every week, according to Nielsen's Audio Today report. At the same time, it's a medium fighting to keep cracks from widening. How its biggest players handle the next few years will be critical to its health.(Ad Age)
I don't think radio will completely vanish any time soon. People will always want to listen to news or music or talk shows while relaxing and without straining their eyes to look at a screen.
