More can be written, but at least for discussing the start, you might like "Did people believe the moon landing was a hoax when it first happened? Was this opinion ever considered more than a silly conspiracy theory?" by [deleted], and "Did people start accusing the moon landing of being fake as soon as it was televised or did this happen much later?" and its descendents by /u/notbobby125 and /u/itsallfolklore.

These are about the start, but not about the development (so far as I see).

This is not to discourage discussion. More questions, data and debate are welcome.
