> It does mention Windows NT but honestly nobody really cared about that until NT 3.0/3.5 and it soon thereafter became Windows XP and laid the foundation for modern Windows.

Fun fact: NT 3.1 was the first version of NT, released in 1993. It was versioned like that to match Windows 3.1 which had been released the previous year.

And NT really took off with Windows 2000. Not just business people but more ordinary people were using it as a more stable alternative to Windows 95/98 (albeit lacking some compatibility, especially with games).
