Kourtney, Kim, Khloe, Robert, Kylie and Kendall Kardashian

The Kardashian brood got its start after O.J. Simpson lawyer Robert Kardashian married Kris Houghton. The couple had four children together -- Kourtney in 1979, Kim in 1980, Khloe in 1984 and Robert Jr. in 1987 . After Houghton and Kardashian divorced in 1990, she remarried Olympic gold medalist Bruce Jenner in 1991. He had his own brood of four sons -- Burt, Casey, Brody (of "The Hills" fame) and Brandon Jenner. The modern-day Brady Bunch welcomed two more daughters, Kylie and Kendall Jenner, in 1995 and 1997.

Thanks to E!, the Kardashians have taken over reality television with their series "Keeping Up With the Kardashians," which has spawned spin-offs including "Kourtney and Khloe Take Miami," "Kourtney and Kim Take New York" and "Khloe and Lamar." The female siblings have also tried their hand at acting and modeling but started off as businesswomen-turned-socialites.
