Seinfeld premiered 25 years ago on July 5, 1989 and ended nine seasons later in 1998. Though it seems like the stars have been immortalized as their 90s selves in syndication, almost all of them have gone on to have pretty successful careers. Check out what the core cast has been up to:

Julia Louis-Dreyfus played Elaine Benes on “Seinfeld,” but plenty of people know her other characters. “The New Adventures of Old Christine” starred Dreyfus in the titular role for five seasons as a woman moving on with her life after a divorce.  She is currently starring in HBO’s political comedy “Veep” as Selina Meyer, the Vice President of the United States. Last season’s finale put Selina in the oval office after the President resigned. Next season, viewers will find out if Selina win the election for President while also taking over President.

Jason Alexander (not the one who married Britney Spears for 55 hours) played George Costanza throughout the series, and actually had a sucessful stage career before the show. He won the 1989 Tony Award for Best Featured Actor in a Musical for "Jerome Robbins' Broadway." “Seinfeld” fans haven’t actually seen him consistently since the series ended. Aside from a guest spots on various shows (including “Community,” “The New Adventures of Old Christine” and “Curb Your Enthusiasm”), Alexander has been doing a lot of voiceover work. His voice can be heard in “Dilbert,” “The Cleveland Show,” “American Dad!” and plenty of others.

Audiences loved Kramer, but his portrayer, Michael Richards, is a little less loveable. Out of the main cast, Richards has worked onscreen the least since Seinfeld ended. He has done stand up and got into some trouble for racist remarks during a show in 2006. This year, Richards costarred in Kirstie Alley’s TV Land comedy, titled “Kirstie,” as Alley’s driver.

Jerry Seinfeld not only starred in but also created “Seinfeld,” and he has kept himself rather busy since the show ended. Seinfeld has had recurring roles on “Curb Your Enthusiasm” and, most recently, “Louie.” He also created “The Marriage Ref.” NBC describes it as a reality show where, “couples will appear in-studio and face a panel of 'experts' composed of top celebrities and comedians who will weigh in and decide which spouse is right.” Seinfeld also created and writes his webseries, “Comedians in Cars Getting Coffee.”
