The deal with Comcast and E! Entertainment was organised by the matriarch and manager of the family, Kris Jenner. It includes her daughters Kim, Kourtney and Khloe Kardashian as well as Kylie and Kendall Jenner.

The father of the younger two Jenner girls will not be part of the show with Kris and Bruce Jenner filing for divorce in 2014. Jenner has signed his own deal with E! for a reality program that will follow his transition from male to female.

Kim's husband Kanye West is also not included in the $US100 million deal.

The new deal is believed to be the largest deal ever signed for a reality program. Keeping up with the Kardashians follows the family through their everyday life and is about to screen its 10^th season.

Until now Kim earned $US80,000 per episode, raking in a total of $US1.6 million, according to TheRichest.com, but the breakdown of the new earning percentages is unknown.

The bulk of Kim's fortune however comes from public appearances and her family's clothing line, which makes upwards of $US600 million, and a video game which reportedly made her $US85 million last year. As a reality TV star she only ranks No.13 among the highest earners (see the top 10 below), behind Nicole "Snooki" LaValle (at No.12) and Gordon Ramsay (at No.11).

Each season of Keeping up with the Kardashians runs for 20 episodes, so the six women are now earning around 12 million cumulatively per episode, putting them among the best renumerated television talent ever.

Charlie Sheen earned $US1.8 million per episode in Two and a Half Men, as did Ray Romano in Everybody Loves Raymond.

The cast of Friends, and also Jerry Seinfeld earned $US1 million per episode, as will the cast of The Big Bang Theory from this season on.
