There are still countries that won't be going digital for a long time yet (they're deep in the Third World.) As long as they're still on good terms with our foreign policy (Sorry North Korea, Iran, Myanmar, et al), there's a chance they COULD be sold there.
I'm sure there's still many Pacific Island nations that have yet to go digital.
Would be kind of hard to transmit 316,000 watts discreetly in the US. Secondly, the sheer SIZE and voltage needs of those things are a problem.....
Perhaps they could be converted to FM or something else. But radio will be the next thing to go all digital (certainly not immediately, but I know that's the next big push.)
They also make lovely flower planters ;D.......
