One of the most popular and longest-running franchises on network TV is One Chicago on NBC, which started when Derek Haas and Michael Brandt created Chicago Fire and released it in the fall of 2012, and was consecutively followed by three spinoffs Chicago PD, Chicago Med, and Chicago Justice. Every show in the One Chicago shared universe has had varying degrees of success. Some TV series have performed better than others, while one in particular was an epic fail many would rather forget about. Nevertheless, NBC’s procedural franchise has prevailed over the years, resulting in major milestones and impressive accomplishments.
