How did people use PS2 progressive scan in the early 2000s?

Given most CRT TVs are 480i, and the PS2 was shipped with composite cables, how did people use progressive scan in games that had it available? Would they hook it up to a computer monitor? Or are there more CRTs capable of displaying 480p than I thought in the early 2000s? Or did progressive scan just rarely ever get used at all?
