What the heck do you call it anyway? It’s not radio because it’s not broadcast on RF, although if you listen to it over your WiFi or 3G/4G Cell then it is RF. It’s not a podcast because it’s streamed live, although you CAN download it later and listen to it on an iPod.
Neither fish, nor fowl. I don’t know what to call it. Netcast? Maybe.
I do know that before this moment it was almost impossible to do on a shoestring. The hardware we’re using for The Squirrel Report would have cost hundreds of thousands of dollars just a decade ago. Phone lines for dial in would have cost thousands each month. Forget the live streaming, that just wasn’t practical. It’s only in the last year that the cost of streaming live (quality) audio has dropped to where I can afford it. (As long as too many people don’t listen at once)
Now I can produce and distribute a live call in audio show each week for less money than a day at the range. A lot less.
Of course creating it is one thing.
Getting people to listen, well that’s a whole ‘nother thing entirely.
