The entire 2001-2002 season of Third Watch was affected and re-directed after 9/11. The season started with a special episode with real emergency personnel talking specifically about the human loss within the “brotherhood” on that day.
After that, there were references to characters working “at the pile” which is what the excavation site came to be known, and scenes of the personnel loading on to city busses after their regular work shifts to go down to work.
There were also characters exhibiting many of the physical symptoms which plagued those who worked at Ground Zero; eye infections, upper respiratory infections, a plaguing, hacking cough, and a political dig at the Guiliani and Bloomberg administrations for failing to disclose exactly what the GZ personnel had been inhaling since the EPA did studies and knew.
There were several (previously unseen) characters who were said to have lost their lives, and they showed a dramatization of what happened in the firehouses around the city when one of theirs was found – how everyone was called and everyone from the house went down to carry out the body.
And, most poignantly, in an extended storyline which stretched several episodes, a main character’s father, an FDNY chief, was found when the command post of the tower one lobby was finally reached in the excavation, and the entire episode was built around the funeral and an extended eulogy to all the fallen and the city as it was up until that morning.
Law & Order had an episode in this past season in which a woman who worked at the WTC was murdered late on the night of 9/10 and her body was taken and dumped at Ground Zero in all of the confusion immediately after the buildings collapsed. (The killer just happened to get “lucky” to have such a perfect way to hide his crime.) There was an extended plot there with regard to the financial settlements which have been extended to families of 9/11 victims.
Law & Order: Criminal Intent has made several references to the day, about people moving businesses out to Queens because it “seemed safer” and numerous allusions in an episode about Islamofascist terrorists intending to act as suicide bombers at a Veteran’s Day parade.
Not surprisingly, none of the comedies which are set in that bizarre, parallel universe NYC have made even a passing reference.
