I don't know if I would call the Chicago shows the most successful crossovers. I'd say the NCIS and CSI franchises have done far better in this regard.The most successful crossover in recent years has been the Chicago Trilogy on NBC (Chicago PD, Chicago Fire and Chicago Med). Characters from one show appear on the other two shows very easily and in fact two of the characters are siblings and two others are dating each other.
