We have used a High Voltage DC link to share power with France (due to different peak demand times) ... initially a 160MW connection and now a
2GW linkAlso to a smaller degree with Belgiumn, NL and Eire
So DC still in use.
All the main undersea national interconnectors are DC (not sure about short ones like to Isle of Wight), I believe partly because of cable capacitance but also because the UK and French grids are not synchronised.
I can just about see a case for having DC circuits around a house (although since switched mode power supplies are cheap and efficient, I'm not even sure about that).

The new Western Link from Scotland to Deeside, Wales is 400kV DC.
AFAIK the first serious submarine cable was in 1954:
Unless you include various DC systems in the USA and UK that existed before.
