VHS was replaced by VCD here in Asia pretty quickly. I assume that you mean "for some values of replace". For read-only that may be true. For write-once and write-many it's (far) less clear. I think that there were vanishingly few VCD recorders available here. And even now DVD recorders are not an 'every home has one' item, unlike VHS recorders.
