From Doctor Who (new) Series 8, Episode 2, "Into the Dalek":
DALEKS: Seek, locate, destroy. Surrender is not accepted.
DALEK: Exterminate. Advance. Seek, locate, destroy.
DALEK 2: Seek, locate, destroy.
DALEK 3: Exterminate.
I always assumed that "Seek, locate, destroy" was just a typical Dalekky thing to say, like their second favourite phrase after "Exterminate". Then recently I discovered there's an episode called "Seek, Locate, Destroy" in the TV series Blake's Seven, created by ... Terry Nation, a.k.a. the real-world Davros, a.k.a. the guy who created the Daleks.
Has the Daleks' "Seek, locate, destroy" ever been acknowledged as a Blake's Seven tribute?
