Tracy has a daughter of her own, Naomi Clark, who dates jock Ethan Ward whom she soon breaks up with. Annie and Ethan then pursue a relationship after having dated the summer prior to Annie moving to Beverly Hills, when Annie was visiting her grandmother for the summer. Both girls alternate between being friends, enemies, in a love triangle, and almost sisters, due to their parents' child. Their respective mothers find themselves in a love triangle of their own after Tracy's marriage to Charles Clark implodes and she appears to want Harry back. Naomi's fight with Annie forces her out of the crowd after she starts her many plots of manipulation and revenge when she uses Annie's ex-boyfriend from Kansas, Jason, as a weapon to get back at her for hiding her relationship with Ethan. She becomes friends with a group of older girls and starts flirting with Ozzie, a rather alternative student, and later becomes attracted to a bartender named Liam, whom she soon finds out is actually her age and becomes a student at West Beverly High. Meanwhile, Ethan and Annie's relationship hits the rocks as he begins to rethink his life after a car accident and gets more or less attracted to Rhonda, the girl he hit. Soon Naomi and Liam begin a romance, and once she becomes friends with Annie again, Liam's repetitive indecisiveness begins as he wants to pursue both of them.

Naomi's best friend, fallen starlet Adrianna Tate-Duncan, battles a drug addiction. This gets her into trouble when Harry decides to raid the school, thanks to the help of a cop, Kimberly McIntyre, undercover as a student. Kimberly begins a relationship with teacher/lacrosse coach Ryan Matthews, which gets him into trouble with the school. Guilt-ridden, Kimberly does her best to solve the case, giving Ryan his job back, although he takes a leave of absence to rethink his life, and Adrianna lands in rehab, after almost getting Naomi in legal troubles as she took the blame for the drugs. There, she begins a relationship with Navid Shirazi, head of the school's paper and Dixon's best friend, who paid for her rehab. Navid and Adrianna are in completely different friend groups in high school. Adrianna was more outgoing and popular while Navid was more focused on his studies. Navid's dream was to have an opportunity to date Adrianna. Although at first she only does it to "repay" him, they start to genuinely care about each other. Adrianna later discovers she is pregnant as a result of her promiscuity while she was addicted. After telling Navid of her pregnancy, he breaks up with her. It is later revealed that the father of Adrianna's child is Ty, although it is unclear when they slept together. She and Navid get back together when he realizes that even though she is a mess he can't get over her which leads to their engagement, although he alienates his family when he tells them that the child is not his and gets upset when Adrianna reveals her daughter is Ty's. Navid's family is very close-knit and is in some ways conservative. Ironically, this only applies to some areas of life, seeing that his dad runs an adult entertainment business.

Another featured character is Erin Silver (who goes by her last name), Kelly Taylor and David Silver's half-sister and Naomi's former best friend, until Silver's father's affair is revealed by Naomi, although she eventually reconciles her friendship with Naomi. She quickly befriends Annie and starts dating Dixon, who is somewhat taken aback by her not-so-90210 lifestyle, as she is a virgin who doesn't care about popularity. In a multi-episode arc that culminated in a very special episode, it is revealed that Silver has bipolar disorder. Kelly Taylor is now a guidance counselor at West Beverly and has a son named Sammy. Kelly becomes Silver's guardian after their mother proves to be an inadequate caretaker for Silver due to her alcoholism. Kelly briefly dates Ryan but discovers that he also slept with Brenda, re-creating the rift between the two friends. Following Brenda's discovery that she cannot have children, however, the women are drawn together in an accord once again.

At the prom, Adrianna goes into labor. She gives birth to a daughter whom she gives up for adoption. It is also revealed that Brenda has adopted a child from China. Ethan begins to realize his feelings for Silver, which leads to a confrontation with Dixon and a kiss with Silver. At Naomi and Jen's (her sister) after-prom party, Liam sleeps with Jen. He is mad that Naomi told Jen about his past: he wanted to keep it a secret. However, he was not aware that Jen was Naomi's sister, and upon finding out is horrified. Naomi finds out about it but thinks that Annie was with Liam, not Jen. This culminates in a major fight between Annie and Naomi where Annie is shunned by her peers, runs away, gets in her car drunk, and accidentally runs over a man. Annie is not sure whether or not this man survived.

This is what Liam wants, and their relationship becomes more stable; however, when Naomi is forced to come clean over false rumors she spread claiming that she was sexually harassed by a teacher, Mr. Cannon, Liam decides that he needs a break from her. During this time, Annie and Liam become closer and he consoles her after she overhears her mother, Debbie, confessing to her father, Harry, that she kissed her yoga instructor.

The two become a couple until Navid reveals to Adrianna that he has never stopped loving her, and she dumps Javier for Navid. Although he initially resolves to get her back, Javier becomes angered by this. He tells her that her singing career is over, before dying in a car crash, which Adrianna survives. She steals Javier's songbook and performs one of his songs at his memorial service, which becomes a hit. She is then blackmailed by Javier's uncle, Victor, who becomes her manager and takes a huge portion of her earnings and forces her to do some things she finds uncomfortable, such as taking half-naked photos and forming a snobby famous image that did not exist before. Navid, realizing the blackmail, asks Adrianna not to give in to the threats of Victor. Adrianna decides to take control of her career from Victor after seeing herself on the cover of a magazine.

The first actor to be cast was Dustin Milligan on April 1, 2008,[1] followed by AnnaLynne McCord on April 14.[2] Sachs found Milligan to be "really funny", and changed Ethan to better represent his personality. McCord was cast because, according to Sachs, "she's someone who is worldly, and there's a sophistication to her that's interesting".[3] The role of Annie was given to Shenae Grimes, who says she was raised watching the original series.[4] Sachs and Judah had seen Grimes' work before and knew "she had the acting chops", and she was cast after acting a dramatic scene which she "just killed". Sachs stated, "she can act, she's beautiful, and she can give this sweet cuteness [that lets us see] through her eyes into this world."[3]

Lori Loughlin auditioned for the role of Debbie and was given the part straight away. Sachs thought that Loughlin was too established to read for the part, but realized that she understood the role immediately. The producers were fans of Jessica Walter after watching her film, Play Misty for Me. Sachs found that Walter knew pieces of scenes, and suggested "stuff that works".[3] Sachs described Ryan Eggold, who portrayed Matthews, as "a sophisticated actor, and he's also very funny". Sachs believed that every time Eggold would be on screen, "people are going to go, 'Wow!'".[3] The producers were looking for an actor who could portray Silver as a "quirky kid who moves to her own beat". Sachs explained that Jessica Stroup "came in dressed for the part, artsy and quirky, and she had her hair up and she had a bandanna. She nailed it."[3] The producers were fans of Tristan Wilds for his acting on The Wire, and hoped to hire him as Dixon from the start of casting. When asked about Michael Steger, who portrays Navid, Sachs said "he's just great".[3] Rob Estes, the last actor to join the series, was a previous cast member of the first Beverly Hills, 90210 spin-off, Melrose Place. Estes was sought by The CW to play Harry,[5] but was contracted on the drama Women's Murder Club. When that series was canceled, Sachs called Estes and explained the spin-off to him, and he thought it was a great idea. Sachs promised that although he was playing a parent, he would not "be furniture... as in the seldom seen or heard parents who populate many youth-centric series, like the Walsh parents on the original 90210."[3]

The CW confirmed that Jennie Garth, Shannen Doherty, Tori Spelling and Joe E. Tata would be returning in recurring roles as their original characters.[6] Sachs was familiar with Garth, and talked to her about a possible role in the series. Garth agreed to star on the series without reading a script after brainstorming ideas with Sachs.[7] The producers offered Garth a role as a series regular, but she opted to sign on as a recurring character.[8] Doherty decided to appear after talking with Sachs, but her appearance was moved to the second episode.[6] Sachs described Tata's casting as an accident; a friend told Sachs that he had seen Tata in a store, which led to the offer of a recurring role in the series. Sachs said that Tata was ecstatic about the idea and agreed.[9] After reading the script, Spelling expressed interest in returning, and the writers decided to give her character her own fashion line.[9] Spelling was scheduled to appear in the première, but due to personal reasons and the birth of her daughter, she opted to appear later in the season.[10]

Once pitched, the project was put on the fast track by The CW, and an order of the pilot was expected by the end of the month. The Beverly Hills, 90210 creator, Darren Star, was announced not to be involved with the project. The only surviving element from the original series was believed to be Creative Artists Agency, the talent agency which conceived the spin-off idea. Veronica Mars creator Rob Thomas was in negotiations to write the pilot and Mark Piznarski was in talks to direct it.

A detailed breakdown of the pilot written by Thomas was released on March 17, 2008, containing information on the plot and characters which would be in the series. None of the characters were related to the original series of 90210 which again aired a few years before except Erin Silver played by Jessica Stroup; however, the new series featured a similar premise: a family with two teenagers who recently moved from the Midwest to Beverly Hills. To reflect the situation at the Beverly Hills school, where around 40 percent of the students were of Persian descent, a student named Navid Shirazi was created. Thomas intended to introduce The Peach Pit, the diner from Beverly Hills, 90210, but noted that it would not be featured in the pilot. The writer considered giving the siblings a job at a movie theater, as he did not want them to use their parents' credit cards. Thomas revealed that there were plans to reintroduce one of the original cast members, but had not met with any of them to discuss a role. Thomas later elaborated the producers wanted to see "as many of the original cast members as possible", but were careful not to "parade them all out in the pilot".

On April 14, 2008, Thomas announced that he was sidelining the series to focus on his two pilots for ABC. Gabe Sachs and Jeff Judah were hired as the new executive producers and wrote a new version of the script in late April. Sachs said that although Thomas had a "great script", their version of the script was edgier. Judah said that they were trying to ground their script in reality, with real character stories and emotional stories. The writers wanted the audience to relate to the characters' problems, which they wanted to be truthful and emotional, but also comedic. The pair were interested in telling several stories simultaneously, featuring many characters.[11] The pair changed the surname of the main family from Mills to Wilson, along with changing the name of the mother from Celia to Debbie. The pair also told reporters that they would be adding their "comedic impulses" to the script.[4] Sachs and Judah found the parents to be an important part of the series, and designed to be contemporary parents.[11] Since the producers were both fathers, they designed the script to include more prominent adult story lines and a strong point of view on parenting. Judah was interested in focusing on how the family kept their moral center when moving to Beverly Hills, and the way the parents dealt with their teenagers.[12] On May 11, 2008, one day before The CW's upfront presentations, the network officially picked up the series for the 2008–2009 television season.[13]

Despite the first season having the highest ratings of the entire series run, the show was largely considered unsuccessful during its first season. The characters were a hit. After disagreeing with the network executives over the series' storylines, Sachs and Judah ended their tenure as producers. The CW wanted the series to have a female perspective and focus more on teenage life and glamour; however, Judah and Sachs were more comfortable writing for men, featuring family stories. The studio brought in Rebecca Rand Kirshner Sinclair, co-executive producer of the popular show Gilmore Girls, to revamp the failing 90210. Sinclair is largely credited for saving the show, which had steady ratings in its third season. For the remainder of the first season, Judah worked in post-production, including editing and music supervision, while Sachs ran the production on set. Rebecca Sinclair began retooling the series as head writer and formally took over the show at the start of season two.[14] In late February 2009, Sinclair signed a seven-figure deal with the producers to serve as executive producer/showrunner for the series' second and third seasons.[15]

On February 16, 2010, The CW renewed the show for a third season.[16] It was also moved to Mondays at 8/7c.[17] On April 26, 2011, The CW renewed the show for a fourth season.[18] On March 17, 2011, it was revealed that Sinclair would step down as executive producer when her contract expired at the end of season three.[19] It was later announced that former Life Unexpected executive producers Patti Carr and Lara Olsen had been hired to take over the series.[20] The show also returned to its debut timeslot, Tuesdays at 8:00 p.m.[21] On May 3, 2012, The CW officially renewed 90210 for a fifth season.[22]

DVR ratings for the series have sometimes doubled its broadcast ratings.

On January 13, 2013, CW president Mark Pedowitz stated that though the show hadn't had a season-six renewal in place, the show would most likely be back the following year for what would've been its final season as he said he was a "big believer in giving fans a very satisfactory conclusion" for a long-running show. However, on February 28, 2013, the announcement came that the fifth season would be its last.

On March 13, 2008, Kristin Dos Santos of E! confirmed that the series would be a spin-off with new characters and not a remake.[23] In order for the project to be ready for the network's "upfront" presentations to advertisers in May, casting began before the script was completed.[24]

Original series actors Shannen Doherty, Jennie Garth and Joe E. Tata signed on for recurring roles during early production.[6] Sachs was familiar with Garth, and talked to her about a possible role in the series. Garth agreed to work in the series without reading a script after brainstorming ideas with Sachs.[11] Initially, the producers offered Garth a role as a series regular but, she opted to sign on as recurring instead.[8] Sachs met with Doherty over dinner and told her about the 90210 spin-off. Over the next few weeks, they established Brenda's backstory as a 'name' stage actress and Doherty agreed to guest-star in several episodes,[11][6] appearing in the credits during the first half-season. Otherwise, Doherty only appeared in supporting roles.

From early on in the news reports of the upcoming series through most of the summer, it was reported that along with Doherty and Garth, Tori Spelling would be reprising her role as an older alumni of West Beverly Hills High. After reading the script, Tori Spelling expressed interest returning, and the writers decided to give Donna her own fashion line.[25] Spelling was scheduled to appear in the premiere, but due to personal reasons and the birth of her daughter, she opted to appear later in the season.[26] Backdrop retail store signage in the first several episodes during shopping excursions scenes and one setup line referring to her role foreshadowed the role that would be unfulfilled. By August 11, it was reported that Spelli of the series after discovering that she was receiving less pay than Garth and Doherty. Spelling asked for her salary of $20,000 per episode to be increased to match their salaries—$40,000 to $50,000 per episode—but when denied she left the show altogether.[27]

The first actor to be cast was Dustin Milligan as lacrosse player Ethan Ward,[28] followed by AnnaLynne McCord as Naomi Clark.[29] The role of aspiring actress Annie Wilson, won by Shenae Grimes, was originally offered to Hilary Duff, who turned it down due to dissatisfaction with the pilot script.[30][4]

Jessica Lowndes was selected to portray actress and singer Adrianna Tate-Duncan, introduced as a theater performer who once had a drug addiction,[31] and would also go through a teen pregnancy and many other serious conflicts as a dark character with many lovable aspects. The Adrianna Tate-Duncan role had been upgraded to a starring role in Jessica Walters' spot,[32] Tristan Wilds was cast as step-brother to Annie Wilson; Lori Loughlin won the role of their mother, photographer wife Debbie Wilson. Michael Steger was cast as the school television news director and congenial very nice guy, Navid Shirazi who maintained the nice-guy status throughout all 114 episodes (2008-2013) of generally being walked on or victimized. ay the part of Harry Wilson, and would only appear in the first two seasons. Estes was a previous cast member of the first Beverly Hills, 90210 spin-off, Melrose Place.[33]

Sinclair announced in March 2009 that the series' second season would rely less on 90210 alums like Jennie Garth and Shannen Doherty to boost ratings. She felt that "the show tried to be a lot of things to a lot of people in its first season [...] I think the center lies with the generation of kids that are in high school now." It was also announced that Dustin Milligan ('Ethan Ward') would not be coming back for season two, while Matt Lanter would be joining the cast as a series regular.[34] Casting soon began for new characters to be introduced in the second season. In June 2009, the series was reportedly looking for an actor to play the recurring role of Teddy, a tennis champ returning to West Beverly.[35] Actor and model Trevor Donovan was later cast in the role.[36] Ann Gillespie returned in the second season for multiple episodes as Jackie Taylor, Silver and Kelly's mother. Her character was once again sober and hoped to reconnect with her daughters after being diagnosed with cancer.[37]

One of the show's locations was a complex on Waverly Drive in the Los Feliz neighborhood, designed by architect Bernard Maybeck in 1927 and best known as the convent of Immaculate Heart of Mary.[38]

Most reviews of the pilot were average. Metacritic gave the episode a Metascore—a weighted average based on the impressions of a select 12 critical reviews—of 46, signifying mixed or average reviews.[71] Matthew Gilbert of The Boston Globe felt that like the original, 90210 was "pretty good". Gilbert said that the episode "seemed to take forever to set up some remarkably bland plotlines", which he found had been executed with more finesse by other teen soaps. The reviewer criticized the writers for "unimaginative material", and commented on the risqué oral sex scene. Gilbert claimed that the characters lacked depth and distinction throughout the pilot, especially Naomi, whom he compared negatively to Gossip Girl's Blair Waldorf.[72] By contrast, Tom Gliatto of People magazine gave Naomi Clark a favorable review, but stated that he felt the cast as a whole had yet to gel.[73] When compared to the original series, Rob Owen of the Pittsburgh Post-Gazette felt that the spin-off covered the same themes—family, friends, teen melodrama, relationships—but with more humor. Owen praised the compelling characters and the acting, and found the dialogue to be more painful than clever.[74]

As the show continued its first season, the response became considerably more positive, and by the second season critical response was favorable. Entertainment Weekly gave the second season an A−, stating that "all it took was a little sunshine to give this show some heat", and that the "new, trashier take is working" after what they considered a "drippy" first season.[75] LaDale Anderson of Canyon News commented on the change between the first two seasons, saying that "the transformation of the characters and storylines in season two has been fantastic", and "sometimes a show needs a makeover and with the right pieces in place a not so good show can become something sensational." The reviewer opined that "what has worked so well [...] is that the characters are not one-dimensional. With most shows characters seamlessly continue to embody characteristics that solely define them, but not here." Anderson also praised the writing, saying it was "intricate and intertwines itself without forcing the storylines to connect; they mesh naturally."[76]
