Why Hasn’t A 3-Show One Chicago Crossover Happened Since 2019?

COVID-19 Was A Big Factor

With more than 680 episodes and 26 seasons under its belt,theOne Chicagofranchiseis undoubtedly one of the most successful ones on network TV. So, it makes sense why NBC would want to take full advantage of its power and release crossovers. However,following “Infection” in October 2019,Chicago Fire, Chicago PD,andChicago Medhaven’t had a three-part crossoverevent. There are many reasons for this five-year hiatus, but most of them circle back to the COVID-19 pandemic.

Plus,the WGA and SAG-AFTRA strikes in 2023 further delayed any potential plans for crossovers.

Why One Chicago Needs Its 3-Show Crossover

Crossovers Have Become A Cornerstone Of The NBC Franchise

It makes sense why it has been five years since the last bigOne Chicagocrossover. However, that doesn’t make the frustration from the lack of them go away. It’s exciting for fans to see their favorite characters from different TV series interact with one another and work together in one major story. Before COVID-19,crossovers were a significant part of the franchise,and it hasn’t felt right ever sinceOne Chicagoentered this drought. Sure,the casts ofChicago Fire, Chicago PD,andChicago Medcan survive (not exactly thrive) on their own, but the shows undoubtedly benefit from crossovers.

It goes without saying that the quality of each series has decreased in the past few years. They haven’t been unwatchable. However,Chicago Fire, Chicago PD,andChicago Medhave all experienced heartbreaking cast exitsand frustrating/repetitive/tedious storylines.
