Fun examples have been old telegraph operators having their lines work without power connected.

As for recent things I didn't even know long range DC still existed.

HVDC transmission is huge in China. Cheap hydroelectric capacity is in the northwestern part of the country, and the big loads are near the east coast. So there are thousand-mile million-volt DC transmission links.

High-voltage DC is becoming more popular, not less.

The technical advance has been the efficiency of high-voltage semiconductors.
