They designed their grids independently. No one ever thought it would matter because if you were in one spot, you couldn’t be buying electronics from the other spot.
All of Europe needs to agree because they share power grids, same with the US and Canada, and it was a lot easier to import electronic from across a land border than it was across the Atlantic back then, so it didn’t really matter that they were different.
100 years later, when everything is so much more interconnected, it would be so much work to change all the grid to one system, make millions of devices obsolete, and we couldn’t even agree on a single system.
