Doc Searls says the Net makes radio and TV transmitters obsolete the moment high-enough-bandwidth wireless connectivity becomes ubiquitous.

“We’re one good UI away from the cell phone becoming a radio. (Thanks to the iPhone, it already serves as a TV.) And we’re one smart cell company away from radio- and TV-as-we-know-it from being replaced entirely — or from moving up the next step of the evolutionary ladder. Public broadcasters know that. That’s one reason they now call themselves “public media”, a move that separates the category from its transport methods.

Will this someday be an issue for our networks? Radio Iowa. Wisconsin Radio Network. Nebraska Radio Network. Time will tell.
