The nine shows of the FBIs, Law & Orders, and One Chicago all share a TV universe thanks to Wolf Entertainment, and that means a pretty expansive franchise spread across two networks and dating back to 1990.
Compared to the Law & Orders and FBIs, One Chicago has frequent mini crossovers with actors jumping between shows for cameos.
You can also revisit past crossovers streaming: the three FBIs are all available with a Paramount+ subscription, and the Law & Orders and One Chicago shows are streaming via Peacock Premium subscription.
FBI, FBI: Most Wanted, and FBI: International are just weeks away from a big three-part crossover, months after Law & Order, Law & Order: SVU, and Law & Order: Organized Crime debuted its first-ever three-show crossover.
