You are missing the point. You are correct that thin ethernet might have been the craze. On the PC you would add an ISA or PCI card. So should we only count from when it was added to the motherboards? The point is that the first 10 base T still works if used with modern equipment. That standard is from 1990 and grew extremely fast. Around 1993-1995 coax was considered totally outdated. Fixing termination problems where never fun. A nail in the coffin was 100 Base T which was standardized in 1995. Tokenring and ATM was contenders around that time but lost to ethernet. That kind of backwards compatibility is really amazing.
