I think most of the original D&D creators where more into ancient mythology than popular culture. And for them, their pop culture was the 50s and 60s, which even the oldest here are too young to remember much of.
In the 80s, with the Hickmans and the like, we saw more contemporary cultural influences coming into D&D, but they where played straight for the most part. I think it's fair to say that the UK took a more ironic approach to fantasy at that time. Of course, most home games had many pop culture references, I certainly had daleks in mine.
For something riddled with actual pop culture jokes (many of which are now so dated that you wouldn't notice them) you should look at the original Baldur's Gate computer game.
I don't think Doctor Who and Blake's 7 where much known in the US until at least the late 80s. There was no BBC America exporting them in those days.
