[5] The initial premise of the show was based on the adjustment and culture shock that twins Brandon (Jason Priestley) and Brenda Walsh (Shannen Doherty) experienced when they and their parents, Jim (James Eckhouse) and Cindy (Carol Potter), moved from Minneapolis, Minnesota, to Beverly Hills, California.

The show became a global pop culture phenomenon with its cast members, particularly Jason Priestley and Luke Perry, who became teen idols; the series also made actresses Shannen Doherty and Jennie Garth household names in the United States.

[13] The series begins with the introduction of the Walsh family—Jim, Cindy, Brandon, and Brenda—who have recently moved from Minneapolis, Minnesota, to Beverly Hills, California, as a result of Jim's job promotion.

In the first episode, Brandon and Brenda begin attending West Beverly Hills High School, where they befriend several classmates: the self-centered and promiscuous Kelly Taylor, carefree and spoiled Steve Sanders, smart and driven Andrea Zuckerman, ditzy and virtuous Donna Martin, brooding loner Dylan McKay, and younger and naive students David Silver and Scott Scanlon.

Fox was initially reluctant to have him included as a regular, but Aaron Spelling felt differently and gave Perry a bigger role during the first two years until the network was won over.

Terence Ford and Arthur Brooks portrayed Dylan's father, Jack McKay, in two episodes before Josh Taylor assumed the role.

[2][23][24] Doherty, who was struggling in her personal life with her father's illness, came to an agreement with the producers to phase her out of the show at the beginning of season 4, when Brenda returns to Minnesota for college.

When she caused continuity problems by cutting her hair halfway through filming an episode, the producers and cast requested from Aaron Spelling that she be fired.

However, the show received such a flood of negative mail from fans complaining about Donna being "stupid" for staying with her abuser, that an angry Aaron Spelling ordered that Walters should be fired.

The studio building complex has since been the home to various projects including the 2006 CBS series Jericho, which guest starred James Eckhouse in one episode.

When the Peach Pit was fictionally remodeled during season two, the producers used Rose City Diner in Pasadena, California, to film the exterior of the gang's hangout, and it remained the same throughout the rest of the show's run.

When the 90210 characters began attending the then-fictitious California University in the show's fourth season, the scenes around campus were actually filmed at Occidental College in Eagle Rock.

[41] After a slew of angry phone calls to the network, Fox decided to placate upset viewers by featuring a pregnancy scare for Brenda and Dylan in the second season, as a means of "punishing" the teenagers for their decision.

[42] Executive Producer Charles Rosin criticized this decision, saying "Someday I will write a long article about the censorship that occurred after Brenda lost her virginity at the Spring Dance to her boyfriend (who had been AIDS tested) because she was happy and not full of remorse.

"[43] In February 1992, at the height of the show's popularity, the three main stars Jason Priestley, Shannen Doherty and Luke Perry were featured on the cover of Rolling Stone.

When Jason Priestley guest-hosted Saturday Night Live in 1992, one of that episode's sketches, which parodied Beverly Hills 90210, involved that town's zip code being changed to 90218 due to the 1990 Census redistricting.

The sketch ends with the zip code "Beverly Hills, 90210" retained as their rich and powerful parents lobbied the US government not to redistrict.

Music from former MMC members Justin Timberlake and JC Chasez of 'N Sync also was originally used during several opening title sequences during the mid-to-late seasons of 90210.

A VH1 promo for I Love the 90s featured Hal Sparks and Michael Ian Black sitting in the Peach Pit, with Beverly Hills, 90210's theme music playing.

In 2021, Beverly Hills, 90210 was one of the shows featured on season 1, episode 3 of Vice Media's Dark Side of the 90's entitled "TV for Teens.

On November 5, 2013, Paramount (CBS Home Entertainment) released Beverly Hills, 90210 – The Complete Series on DVD in Region 1, with extra bonuses not available on the season sets.

Jennie Garth, Tori Spelling, Brian Austin Green and Ian Ziering made appearances as their Beverly Hills, 90210 characters in the first few episodes of Melrose Place.

The series was introduced via the characters Hillary Michaels, the mother of Melrose Place's Amanda Woodward, and model Sarah Owens—both of whom had appeared in a multi-episode run on MP.

In guest appearances, Jennie Garth, Shannen Doherty and Tori Spelling reprised their roles as Kelly Taylor, Brenda Walsh and Donna Martin, respectively.

Joe E. Tata also reprised his role as Nat, owner of the Peach Pit, diner turned coffee house, for a couple of episodes at the beginning of the show's first season.

The show is an updated version of Melrose Place, featuring a group of young adults living in a West Hollywood apartment complex.

[53] The bulk of the original cast is attached, including Garth, Spelling, Shannen Doherty, Jason Priestley, Ian Ziering, Brian Austin Green and Gabrielle Carteris.

[53] On February 1, 2019, Spelling confirmed that a reboot of the show was underway, stating, It is the OG crew back together, and we're playing heightened versions of ourselves.

[54] She added that "almost everybody" from the original cast was set to return, with Luke Perry's participation initially presumed to be limited because of his work on Riverdale until his death on March 4.

[11] According to a press release on April 26, 2019, the revival — retitled as BH90210 — would feature the cast playing "heightened versions of themselves" in an irreverent drama "inspired by their real lives and relationships with each other.
