"Blue Bloods," which aired on CBS from 2010 to 2024, followed the Reagan family, a lineage of law enforcement officers in New York City, led by patriarch Frank Reagan, played by Tom Selleck. The series concluded after 14 seasons, prompting the creation of "Boston Blue," which centers on Danny Reagan's transition to the Boston Police Department following his son Sean's injury in a fire.
