You mean DC almost prevailed. It wouldn't have in the long run, no matter what. The line losses and requirement of a generating station on every block would have mad it unusable. As in Atlas Shrugged, in order to fix the system it must first be totally crashed......................
DC's problem is distribution and delivery, with enormous losses in transmission and of course, safety issues.
Historical note: Tom Edison was an SOB who stole as much as he "invented," and a bit of thug besides.
Tesla? Serbia was having some sort of weird science/physics/math renaissance in those days .. which is very strange to contemplate. My present favorite Serb of the era was Milankovitch, whose "Glaciation Cycle" rather neatly encapsulates global climate change, has been rigorously demonstrated, and is accepted by every one from Archaeologists and Astronomers, to Paleontologists, to Geophysicists, Astrophysicists, Zoologists .... i.e. everybody with a brain, with the strange exception of Climatologists, who apparently have no access to scientific instrumentation or data!
