If you’re a TV fan, there is plenty to watch right now. And if you’re a fan of crossovers — even minor ones with a character or for an episode — you’re also in luck. Primetime television has been filled with shared universes, especially in recent years.
If you’re into procedurals (like the NCISes — which united for a three-show crossover — or Dick Wolf‘s extended universe), zombies (The Walking Dead universe), or superheroes (the Arrowverse), you’re covered. In fact, crossovers aren’t necessarily beholden to a network: Chicago P.D.‘s (NBC) Tracy Spiridakos went over to FBI (CBS).
So scroll down as we examine the shared universes currently part of primetime television. (Notes: We’re only including shows that have aired, have premiere dates, or have been ordered to series, not any in development.)
