It had, Modula-2 and Pascal dialects usually had richer libraries.
For example check Turbo Pascal libraries, including Turbo Vision, already on MS-DOS.
C took off thanks to UNIX's adoption, like JavaScript on browsers nowadays, it became the language to use for anyone working on the enterprise on those new shiny UNIX boxes.
In Europe it was just another systems language to choose from, back when CP/M and other 8 / 16 bit systems were common.
Both C compilers and Turbo Pascal already existed in CP/M, which preceded MS-DOS.
Also there were C, Pascal and Modula-2 compilers available for ZX Spectrum.
And on my part tiny of the globe I can guarantee that everyone only cared about x86 Assembly, Turbo Basic and Turbo Pascal, with Clipper for business stuff.
I only got to learn C in 1993, after having been a Turbo Pascal 3, 5.5 and 6.0 user.
Being able to compile stuff on CP/M wasn't much help if you wanted to develop MS-DOS applications.
I first used C in 1983 on MS-DOS, I didn't use UNIX until a couple of years later. I bought Turbo Pascal 1.0 when it was released but already had a C compiler at that point.
