Many of the celebrities featured in the crime series are familiar faces, and many have been there since its beginning.

What are Blue Bloods?

Blue Bloods, an American drama series, has been airing for 12 seasons.

This show features a multi-generational family of cops dedicated to serving New York City.

According to the show’s description, Frank Reagan is New York Police Commissioner. He heads both the police force as well as the Reagan brood.

He manages his department as diplomatically and family-oriented as his father Henry. Frank’s eldest son Danny, a veteran detective, family man, and Iraq War vet, is a source of pride, concern, and joy. He sometimes uses dubious tactics with Detective Maria Baez to solve cases.

It is not yet clear if the show will return for a thirteenth season.
