Finland tried broadcasting the $BTC blockchain over TV signals in 2014.

Kryptoradio pushed blocks, transactions, and price data through 90+ TV stations. You could sync a node without internet. 95% population coverage by November.

One-way only—you could receive but not broadcast transactions back. Needed a separate channel to send.

Project died in December 2014. Ran out of money.

Wild experiment for its time. Shows how early builders were thinking about censorship resistance and alternative infrastructure before it was cool.
