How long before '90s nostalgia hits the scene?

That makes for a mental picture I prefer not to picture.

Here’s something else I remember from the '90s: Perhaps it was only an emotional adjustment to the early Information Age, but Gnosticism – the idea that there are hidden forces at work, human or supernatural – became even more prominent in popular culture.

Modern expressions of gnosticism in this sense go back at least to Illuminatus!, but in the 1990s it really came into its own. See The X-Files, VR.5, Wild Palms, Millennium.
