| In some way it is short-sited, as radio is a good backup medium for global communications in case the entire Internet ever goes down. Vacuum tubes also aren't vulnerable to nuclear weapon electro-magnetic pulses. However, other than ham radio enthusiasts I guess no one listens to analogue radio anymore. |

It's remarkable that these powerful stations spend most of their broadcast day transmitting that content. | |

| It's hard to believe that civilisation has lost the ability to build longwave radio transmitters. |

| We do spend out quite a lot here in the UK for the BBC. They could easily dump a couple of expensive presenters and use the savings for vacuum tubes, if that is what is needed. No idea where vacuum tubes were invented but I'm sure the BBC could find someone to make them. |
