90210 is an American teen drama television series, developed by Rob Thomas, Gabe Sachs, and Jeff Judah, that aired from September 2008 to May 2013. It is the fourth series in the Beverly Hills, 90210 franchise created by Darren Star. The series was produced by CBS Television Studios.
Like its predecessor, the show follows the lives of several wealthy students attending West Beverly Hills High School in the upscale and star-studded community of Beverly Hills, California. The show later focuses on the same group of friends when they graduate and begin their lives in the adult world. Some attend college at California University, while others begin exploring avenues beyond post-secondary education.
The show originally revolved around the Wilson family, including new Beverly Hills residents Annie Wilson (Shenae Grimes) and Dixon Wilson (Tristan Wilds). Their father, Harrison Wilson (Rob Estes) has returned from Wichita, Kansas, to his Beverly Hills childhood home with his family to care for his mother, former television and theater actress Tabitha Wilson (Jessica Walter), who has a drinking problem and clashes with his wife Debbie Wilson (Lori Loughlin). Annie and Dixon struggle to adjust to their new lives while making friends and yet adhering to their parents' wishes.
During the first two seasons, cast members from the original series made appearances, including Jennie Garth, Shannen Doherty, Ann Gillespie, Tori Spelling and Joe E. Tata. After the second season, however, they were not featured and were rarely mentioned. The primary connection between the two series was the new series' character of Erin Silver (Jessica Stroup), the half-sister of Kelly Taylor and David Silver from the original series.
