When Autumn learns certain words, Radio, Telephone, TV, her definition of these words will be entirely different from the way we think of these words.
Take Radio. Currently, Autumn can listen to the radio on a radio (yes, they exist), but more and more we can 'listen' to the radio online via podcasting. At home, we listen to This American Life, RadioLab, Car Talk, and The Curling Show all online. (You really will like all of these. No matter who you are.)
Now. how far away are we from a radio that can connect to the internet and pick up podcasts of your favorite shows? The technology exists. And since it does, I think we're in a golden age of radio. Where, instead of tuning into news-like shows that seem repetitive, you can pick other shows you like and listen to them when you want.
The next revolution is the elimination of the hour show. With the exception of The Curling Show, above, the shows we listen to are Made for Radio. They are hour shows and have acts to keep the shows moving through the hour. Not so with the curling show. It can be 10 minutes, or 20. It's dependent on the content, not a radio schedule. And soon, shows like This American Life might realize there's more of a market for snippet podcasts and create shows that work like that.
Just think: in your car, you hit wireless hotspots all the time. Why not have a wireless radio? Or whatever it is that Autumn calls it.
