It’s also worth noting that all three One Chicago series have been renewed for three more seasons, bringing Chicago Fire to at least an eventual 11 and Chicago Med to at least eight.
Just think how far Foster could go in three years on Med vs. three more years as a paramedic on Fire!
The series are going to need to mix things up to remain interesting and dominant in the ratings, and the three-season renewals present opportunities for planning a long game.
(Chicago P.D. is currently guaranteed through Season 10.)
