A bit of trivia for you:
In the film 2001, the computer was named HAL.
Take IBM, move all letters backward one letter, and you get HAL. That's
where the name came from.
Windows NT gets its name from VMS. Move each letter of VMS forward one, and
you get WNT. It was left to the marketing folks to determine what it stood
for... There were many variations, these are the most popular:
New Technology (they originally went with, before dropping it)
Not There (many UNIX and Netware folks used this initially)
Nice Try (ditto above)
