@badastro here's a thing though. The Space Shuttle Enterprise canonically exists in the Star Trek universe (it's depicted in a couple of episodes) as one of a long line of Enterprises. However, it was also actually named after the USS Enterprise from Star Trek.
@badastro related: in (at least) one episode of Dr Who, people are shown watching British soap Eastenders. and in (at least) one episode of Eastenders, people are shown watching Dr Who.
@badastro in Stargate SG-1 (which is definitely sci-fi despite its contemporary setting) there exists a show called Wormhole X-Treme, a sci-fi show with the exact same format and premise as Stargate itself. it's a supreme bit of lampshading.
