Why is radio still prevalent?

People still listen to the radio when it's such an old form of entertainment. I think that's great! These days older things are usually quickly trumped by newer tech, but radio is still around.

It's like iphone 6 replacing iphone 5 soon even though 5 is only a year old. Why is our society so stupid as far as consumerism goes? It's ridiculous.

Radio is the only thing like it. There isn't really a replacement for it. Obviously some people prefer their ipod or a cd (does anyone other than me still listen to cds?) But for the most part radio is just easy, available, and not being challenged by a lot of other stuff

It gives you the ability to have fun enjoying music or talk shows whie you dirving

Old world charm

Because you can listen to the radio while doing all kinds of other stuff: homework, driving, using the internet.

"Why is our society so stupid as far as consumerism goes?"

Capitalism, aka chasing profit. We could produce 5 billion Iphones that last for decades, but it's more "profitable" to produce a billion (that become obsolete quickly) every few years.
