I can think of a bunch of reasons.

1. For its time, the VT100 was pretty compact.
2. It was the first DEC terminal with a detachable keyboard (not counting the GT-40) and if you needed an extension cord, you could just get a headphone cord at Radio Shack.
3. It was the first DEC terminal to implement a standard for control sequences (ANSI controls).

Before then, the VT52 was certainly attractive, same screen size (24 by 80) and upper/lower case (English only, give or take some national variants).  But it's much bigger and doesn't have a separate keyboard.  VT50 seems like it was someone's mistake -- 12 lines, what were they thinking?  Even the VT05 had 20.
