Created by Dick Wolf (Law & Order: Special Victims Unit, Chicago Fire, Chicago Med) first premiered all the way back in 1990 and follows a group of police detectives and prosecutors in New York City.
The NBC (and, in turn, Peacock) crime drama released Seasons 1-20 roughly a year apart from one another between 1990-2010 before taking a brief hiatus. However, it returned in 2022, bringing back some of the show's main characters while also introducing new faces.
