On early PCs, Pascal and C were pretty much tied in popularity. Both were free to implement, and small enough that you could make a fast compiler on a typical PC with only 256-640 kB RAM.
C won because it was more flexible and was chosen by Microsoft, but Pascal definitely had a strong following (it was the original Mac's API language, and on PC it was a major contender thanks to the nice and fast Turbo Pascal IDE).
Ada was a complicated and rigid language designed by a Department of Defense committee. That was not great PR for those early individualist PC users. (Who wants to program in the language of "The Man"?)
If Pascal was a Cessna and C was a Learjet, then Ada was the F-35 -- complex, expensive, late.
