What would retro v-tubing look like?

So: whenever massive technological revolution comes about, we think about how we may have come to similar technologies much earlier. Steam punk is an example of this -- you take modern technology and construct it using old and antiquated technology, based off the fundamental principles of modern technology which can be translated backwards.
Example: a vr headset using crt displays working off our knowledge of optics.

Now apply this idea to early 2000s internet -- knowing now how successful this idea is, v-tubing, how could one have constructed a v-tuber without modern tracking?
