When Kim Kardashian was on Season 7 of "Dancing With the Stars," "Keeping up With the Kardashians" was just a year old, but it went on to become one of the most successful franchises in reality TV history.
After his stint on Season 5 of "Dancing With the Stars," Cuban went from regular billionaire to famous billionaire when he became one of the investors on ABC's hit "Shark Tank."
"Dancing With the Stars'" most successful alums weren't even stars before they were on the show. Brother-sister duo Derek and Julianne Hough entered the show as professional dancers, but have since branched out into their own acting careers. Julianne also took on the role of judge on the show beginning with Season 19.
Brooke Burke-Charvet won the seventh season of ABC's reality competition series in 2008 then parlayed that success into a nine-season run as co-host of the show.
Like Burke-Chavert before her, Andrews went from "DWTS" alum to co-host when she assumed the role for Season 18. Andrews also assumed several new roles as a sportscaster for Fox Sports.
Daytime soap vet Lisa Rinna competed in the second season of "DWTS," finishing in fourth place. Since then, she's gone on to a fruitful reality TV career, including her role as one of the regulars on "The Real Housewives of Beverly Hills."
"Beverly Hills, 90210" star Jennie Garth finished in fourth place on Season 5 of "DWTS," then went on to star in the CW's "90210" revival the following year.
Candace Cameron Bure
"Full House" star took home the bronze in Season 18, then wrote a book about the experience, called "Dancing Through Life." She also serves as a host on the ABC daytime talk show "The View" and will star in the Netflix sequel series "Fuller House."
In 2009, Melissa Joan Hart competed on Season 9 of "Dancing With the Stars," and in 2010 she made her return to TV in ABC Family's "Melissa and Joey" alongside Joey Lawrence (who also competed in Season 3).
"American Idol" vet Kellie Pickler put her reality TV experience to use on Season 16, this time walking away a winner. In 2015, Pickler and her husband Kyle Jacobs scored a CMT reality series called "I Love Kellie Pickler."
"The Fresh Prince of Bel-Air" alum Alfonso Ribeiro won Season 19 of "Dancing With the Stars," then went on to take over for Tom Bergeron as host of "America's Funniest Home Videos" in 2015.
The country-music radio host won Season 27 in fall 2018 despite landing the second lowest scores in the final 4 with partner Sharna Burgess -- and then parlayed that appearance into a full-time mentor role on ABC's "American Idol" reboot. He even subbed in as host in April 2019 when Ryan Seacrest was too sick to tape the live show.
