The first ten episodes of the seventh season aired on Thursday night's at 10:00PM/9:00PM, filling a slot previously occupied by the first season of Burn Notice. The season then took a "fall finale" with the episode "Senseless," coinciding with the 2007 Writers Guild of America strike where show runner/executive producer Warren Leight and the rest of the writing staff participated in the work stoppage; the first ten episodes of the season being the only ones produced. The remaining twelve episodes resumed airing Sunday night's at 9:00PM/8:00PM leading in In Plain Sight starting June 8, 2008.

The sixth season of Law & Order: Criminal Intent premiered on NBC September 19, 2006, and ended May 21, 2007; this was the last season to air original episodes on NBC. This season of Law & Order: CI premiered in the NBC Tuesday 9/8c time slot as a lead-in for episodes of Law & Order: Special Victims Unit; NBC had acquired the rights to Sunday Night Football for the 2006–2007 season. For its first six airings, it faced CBS's The Unit and baseball on Fox. In late October, Fox's hit series House moved opposite L&O: CI. It was hoped that the show could maintain second position, beating the then-marginal The Unit, but that didn't occur. The show's ratings suffered a steep drop and it regularly finished fourth in its time slot. By the end of the season, Law & Order: CI saw its lowest ratings ever on NBC, the episodes "Endgame" and "Renewal" being shifted to originally air on Monday nights. This is the last season the original hard rock theme song was used in the opening sequence before changing to the fast-paced theme song of the now-defunct related series Law & Order: Trial by Jury - coinciding with the show's move to USA Network in Fall 2007.

The fifth season of Law & Order: Criminal Intent premiered on NBC on September 25, 2005, and ended on May 14, 2006. This season featured the series's first two-part episode and "Cruise to Nowhere" was referenced later for an eighth season episode titled "All In". This season of Law & Order: CI remained in its time slot of NBC Sunday's at 9PM/8c, its final season in this slot on NBC; its move to Tuesdays in the sixth season caused a ratings decline. During the 2005–2006 network TV season episodes were up against episodes of Desperate Housewives on ABC and episodes of Family Guy and American Dad! on Fox. The show "roller coasted" in the ratings with the competition, but NBC executives were impressed with the 11 million viewers per week it was able to retain.

The fourth season of Law & Order: Criminal Intent premiered on NBC on September 26, 2004, and ended May 25, 2005. The series remained in its time slot of Sundays at 9 PM/8c, but the season finale episode "False-Hearted Judges" aired on Wednesday, May 25, 2005 at 10 PM ET/9 CT. Stars Vincent D'Onofrio, Kathryn Erbe, Jamey Sheridan, and Courtney B. Vance returned for the fourth season. Around mid-season, star Vincent D'Onofrio fainted twice from exhaustion, once on set and again at his home. Writers René Balcer and Elizabeth Benjamin won an Edgar Award in the category Best Episode in a Television Series Teleplay, for the episode "Want". Almost three months before the fourth season finale, it was announced Chris Noth would join the show in the fifth season, alternating episodes with D'Onofrio, due to his health issues at the time.

The third season of Law & Order: Criminal Intent premiered September 28, 2003 and ended May 23, 2004. Samantha Buck temporarily replaced Kathryn Erbe while she was on maternity leave. Buck appeared as G. Lynn Bishop from episode 5, "Pravda" through episode 11, "Mad Hops."

Season one of Law & Order: Criminal Intent, an American police procedural television series developed by Dick Wolf and René Balcer, began airing on September 30, 2001 on NBC, a national broadcast television network in the United States. Law & Order: Criminal Intent is the second spin-off of the long-running crime drama Law & Order, and follows the New York City Police Department's fictional Major Case Squad, which investigates high-profile murder cases. The first season comprises twenty-two episodes and concluded its initial airing on May 10, 2002. Four actors received star billing in the first season; Vincent D'Onofrio, Kathryn Erbe, Jamey Sheridan, and Courtney B. Vance. Episodes depict Detectives Robert Goren and Alexandra Eames as the squad's lead investigators. Captain James Deakins is the detectives' direct supervisor and head of the Major Case Squad. Assistant District Attorney Ron Carver often attempts to obtain confessions from the suspects, rather than taking them to trial. Law & Order: Criminal Intent focusses on the actions and motives of the criminals, and divides screen time equally between the suspects and victims, and the police's investigation. The season was filmed on location in New York City, although scenes set inside the Major Case Squad department were filmed in a studio at Chelsea Piers, Manhattan.
