Anyway, Industrial involved into Noise and Power Electronics (well, seeing as that Industrial is Noise, it could be debated the other way around... but I think people didn't start recognizing Noise as anything more than spattered experimentation until after Industrial Records came around). During the time Industrial was being established a few bands started experimenting with taking the ideas of Industrial and applying them in small doses to more popular genres, the early stages of Post-Industrial were set by Thomas Leer and Robert Rental, early 80s SPK, and Chrome. Then Front 242 came along established EBM and shazam, Post-Industrial is official (but people were dumb and didn't know about Merzbow, Sutcliffe Jugend, Whitehouse, or Maurizio Bianchi) and thought it was Industrial, or not, I don't really know.
Anyway, shit continued like that, Skinny Puppy and Frontline Assembly's... early works verged on Industrial and something less so, and then there was some house music in America with some distorted beats, then Godflesh, Ministry, Nine Inch Nails, then Rammstein, MSI, and some other crap bands and VNV Nation, Apoptygma shitzerk, Covenant... I think that covers most of the bases. This was all being called Industrial, yet none of it really sounded remotely alike and they were clearly some form of EDM, Synthpop, or Rock/Metal. People are just stupid and called it all Industrial while completely ignoring the fact that Industrial sounded nothing like any of it and the ideals behind Industrial music would never allow it to evolve into other pre-established, popular genres. And STILL no one knows about Merzbow, Sutcliffe Jugend, Whitehouse. Well, ok, some people know Merzbow.
Do I win, yet?
