AFAIK in practice Turbo Pascal won because it was cheaper, faster and provided all the necessary tools that standard Pascal didn't - though those tools were largely inspired from UCSD Pascal and after Turbo Pascal other Pascal implementations basically replicated its syntax, so in a way Turbo Pascal became the defacto standard. I find it kinda amusing that Free Pascal was Turbo Pascal compatible from 1997 but it only fully implemented a standard Pascal mode (the compiler supports multiple dialects) just ~10 years ago (and still doesn't support the Extended Pascal syntax).
