The classic series featured both retellings of older stories (starting with The Daleks, which was closely based on The Time Machine, though more on the 1960 film than the book) but there've been several concepts which it used at least before more famous examples:

Cyborgs in the 1960s (both Daleks and Cybermen)
The generational space-ark in 1966
Space Bugs that lay there eggs inside humans several years before Alien
Egyptian gods as aliens in 1975 (after Von Daniken, but long before Stargate)
A VR environment called The Matrix in 1976
