Francis Xavier `` Frank '' Reagan is the Police Commissioner. Frank 's oldest son Danny is an NYPD detective, his youngest son Jamie is an NYPD police officer, and his daughter Erin is an assistant district attorney. Frank 's middle son Joe was murdered by a crooked cop in the line of duty in events that pre-date the series, when he was involved with the Federal Bureau of Investigation ( FBI ) investigating a group of corrupt NYPD cops. Frank 's father Henry is a former NYPD beat cop who rose through the ranks to Police Commissioner. Each member of the family represents a different aspect of police work or the legal process : Frank as the commissioner, Danny as the detective, Jamie as the beat cop and Erin as the prosecutor. Additionally, while each person 's story might occasionally interweave with another 's, the show also follows the professional relationships with their respective partners and colleagues. Frank with Garrett Moore the NYPD Deputy Commissioner of Public Information and later Sid Gormley the Special Assistant to the Commissioner ; Danny with Detective Maria Baez, Jamie with Officer Edit `` Eddie '' Janko, and Erin with Detective Anthony Abetemarco in the DA 's office. Both Henry 's and Frank 's wives are deceased. Erin is divorced and has one teenage daughter, Nicky, who lives with her. Danny is married to Linda, an ER nurse, and they have two sons, Jack and Sean. Linda dies offscreen between Seasons 7 and 8. Jamie is unmarried, though romantic feelings develop between he and his partner, Eddie ; they acknowledge their mutual attraction during season 7. A show signature is the Sunday dinner scene around the large table in Frank and Henry 's home. The four generations of Reagans gather to eat and discuss their week, which naturally includes current cases or controversies depicted in each episode. The grandchildren often have meaty or moral issue questions which the various adults answer, sometimes with differing viewpoints. The conversation may also include family members ribbing each other, and Henry or Frank dispensing wise advice. Sometimes the conversation breaks down in acrimony because of differing feelings or perspectives among family members on emotional issues, but the family always remains loving and united. The Sunday dinner has been a Reagan family tradition for more than a century.

Beginning January 19, 2011, Blue Bloods was moved to Wednesdays at 10 p.m. for a four - week tryout. In February 2011, the series returned to its Friday night time slot due to the series premiere of Criminal Minds : Suspect Behavior. In the UK, the show helped launch Sky Atlantic by premiering on Tuesday, February 1, 2011, at 10 : 30 p.m. In Australia, the show premiered in February 2011 in a primetime Wednesday slot on Network TEN, then from February 2013 for season two was moved from the network 's primary SD channel to its HD channel one alongside White Collar, then on August 26, 2013, the show moved back to the primary SD channel on Mondays for season three. In New Zealand, the show premieres on July 13, 2013 on TV3 replacing CSI : NY in a primetime Saturday slot after Law & Order : Special Victims Unit. On October 20, 2012, CBS announced that Jennifer Esposito was being dropped from the series, with her character, Detective Curatola, being placed on indefinite leave of absence. Esposito and CBS had been at odds over her limited availability for work after the actress was diagnosed with celiac disease. She had missed a week after collapsing on set earlier in the season. According to Esposito, CBS challenged her request for a reduced work schedule, and further, kept her from finding work elsewhere. In a press release from CBS, the network said that Esposito had `` informed us that she is only available to work on a very limited part - time schedule. As a result, she 's unable to perform the demands of her role and we regretfully had to put her character on a leave of absence. '' Curatola 's last appearance was in the season three episode `` Nightmares ''. ( Four years later, she was hired for the CBS crime drama NCIS. ) According to TV by the Numbers, by committing itself to a third season of Blue Bloods, CBS all but guaranteed a fourth season, because, as a CBS Television Studios production, CBS had a financial incentive to produce at least the minimum number of episodes needed for stripped syndication. On March 27, 2013, CBS made it official by renewing Blue Bloods for a fourth season to begin in the fall of 2013. Blue Bloods was renewed for a fifth season on March 13, 2014. Broadcast ( Edit ) In Australia, the series premiered on Network Ten 's primary channel on February 2, 2011. Due to poor ratings of the first season, Ten moved the series to its HD channel One, which premiered the second season on October 31, 2011. Due to decreased viewership of Ten 's primary channel, season three moved back from August 26, 2013, and season four returned on March 17, 2014. In New Zealand, the series premiered on TV3 on July 13, 2013. In the United Kingdom and Ireland, Sky Atlantic premiered the series on February 1, 2011, with season two returning on October 4, 2011, season three on December 13, 2012, and season four on November 28, 2013. Season five premiered on January 21, 2015. Reruns Reruns of Blue Bloods air nationally in the United States on Ion Television and WGN America, the latter of which airs the show daily. CBS Television Distribution currently distributes the series to local outlets on weekends, with two episodes being offered. Repeats of Blue Bloods air on Pick in the UK Reception ( Edit ) Reviewers have praised the series ' on - location shooting. The New York Daily News praised Selleck 's performance as Frank Reagan, while also praising the family dinner scene for discussion of morally complex issues. The Daily News drew comparisons between Selleck 's characters Jesse Stone and Frank Reagan, saying that both Reagan and Stone are moral, principled men of few words. In Entertainment Weekly 's annual Fall TV Preview, Ken Tucker named Blue Bloods one of the `` 5 Best New Shows '' of 2010. Laura Hudson at Slate stated that the series `` perfectly caters to your perspective on the police '', that it hides how American police deals with race, noting that it `` has a habit of depicting people who speak up against the police as malicious, manipulative, or deceptive -- and a lot of those people happen to be minorities '' as well as that `` accusations leveled at police by citizens are almost always revealed to be fraudulent, and concerns about racial bias are almost always manufactured, deceitful, or overblown '', describing it as `` the perfect white - privilege lullaby ''.
