Season 1 of American television series 90210 aired on the CW television network.
Much like the original series, Beverly Hills, 90210, 90210 follows the move of a family (parents Debbie and Harry Wilson, their daughter Annie and adopted son Dixon). Harry is actually from Beverly Hills and comes back both to look after his mother Tabitha and to work as the principal at West Beverly Hills High School. All of them struggle to adjust to their new lives: Annie has a hard time balancing romances, (starting with rich kid, Ty), friendships as well as popularity and identity; Dixon has issues with his adoption and African-American heritage; Harry and Debbie struggle with the revelation that Harry has a son with Tracy Clark, his former high school sweetheart.
Tracy Clark has a daughter of her own, Naomi Clark, who dates jock Ethan Ward, with whom she soon breaks up with. Ethan gets back together with Annie, whom he had a fling with several years prior. The half-sisters (Naomi and Annie) alternate between friends and enemies in a love triangle. Their fued eventually pushes Naomi out of the "in crowd." Their mothers find themselves in a love triangle as well, after Tracy's marriage to Charles Clark implodes.
Naomi's best friend is fallen starlet Adrianna Tate-Duncan; she battles a drug addiction during the 1st season. When Harry decides to clean up the school with the help of an under-cover cop, Kimberly MacIntyre, Adrianna finds herself caught in the middle of the investigation. Adrianna lands in rehab where she begins a relationship with Navid Shirazi, head of the school's paper and Dixon's best friend. At first she only stays to "repay" him, but 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. She and Navid get back together when he realizes that, even though she is a mess, he can't get over her. They get engaged.
Another featured character is Erin Silver, Kelly Taylor's half sister and Naomi's former best friend, until Silver's father's affair is revealed. She quickly befriends Annie and starts dating Dixon, who is somewhat taken aback by her not-so-90210 lifestyle, as she is a virgin whom 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 a guidance counselor at West Beverly and has a son named Sammy. She briefly dates Ryan before leaving to work on her relationship with former boyfriend and father of Sammy, Dylan McKay. This briefly causes friction with Brenda Walsh as both struggle with their lingering feelings towards Dylan. When Kelly returns, she not only discovers Ryan's relationship with student/cop Kimberly but also that he 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.

On March 13, 2008, it was announced that The CW was developing a contemporary spin-off of Beverly Hills, 90210. The project was put on the fast track by the network, 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 masterminded the spin-off idea. Veronica Mars creator Rob Thomas was in negotiations to write the pilot, and Mark Piznarski was in talks to direct.
A detailed breakdown of the pilot written by Thomas was released on March 17, containing information on the plot and characters of the series. None of the characters were related to the original series; however, the 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 parent's 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". Following rumors of cast members from Beverley Hills, 90210 appearing on the spin-off, The CW confirmed that Shannen Doherty would be returning in a recurring role as her original character. Sachs met with Doherty over dinner, and told her about the 90210 spin-off. Over the next few weeks, they established Brenda's backstory and Doherty agreed to guest star in several episodes. Doherty and Garth told reporters that they were nervous about reuniting and filming scenes together for the 90210 spin-off. While starring in the original series, the actresses were known for feuding on and off the set, which lead to Doherty leaving the series in 1994. The pair had not spoken for years before filming their first scene together, and commented on the amount of buildup and nerves leading towards their first meeting. Doherty commented, "I think when you're 18, your personalities conflict, then you meet up 10 or 15 years later, and the playing ground is totally different and you're fine."
On April 14, Thomas announced that he was leaving 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. Sachs and Judah found the parents to be an important part of the series, and designed to be contemporary parents 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. On May 11, one day before The CW's upfront presentations, the network officially picked up the series for the 2008–2009 television season.
After disagreeing with the network executives over the series' storylines, Sachs and Judah resigned as writers. The CW wanted the series to have a female perspective and focus more on money and glamor; however, Judah and Sachs were more comfortable writing for men. Instead, Judah began working on postproduction, including editing and music supervision, while Sachs ran the production on set. The CW hired Rebecca Rand Sinclair to retool the series as head writer.
The series debuted to 4.7 million viewers and a 2.6 Adults 18-49, winning the night in all key demos, to become The CW's highest rated premiere. It also matched the highest 18-49 numbers set by America's Next Top Model. The first season holds a 46/100 rating on Metacritic.
