This is mentioned in the post:

> Indeed, the stronger explanation for Times New Roman’s long reign isn’t aesthetic excellence, but practicality and inertia. Times New Roman was among the small set of typefaces bundled with early versions of Windows. It was also promoted as “web-safe,” meaning webmasters could reasonably assume it would render properly across platforms. In the early era of digitalization, choosing Times New Roman was often less a deliberate endorsement than a default imposed by limited options. Over time, the habit hardened into a standard, and institutions began to require it without much reflection, effectively borrowing their own authority to confer authority upon the typeface.

And Times is one of the three original Postscript core typefaces, along with Helvetica and Courier.
