Kardashian appeared on the cover, and in a pictorial in Paper's winter issue in 2014 photographed by Jean-Paul Goude. On the cover, her nude buttocks are featured above the caption: "Break the Internet", which generated considerable comment in both social and traditional media. The photos show Kardashian with her hair tied up in a bun, wearing only a pearl necklace, a pair of earrings and black satin gloves, and, on the cover, with her bare back facing the camera, holding a sequined gown below her bare, oiled-up buttocks, while smiling broadly at the camera. A Time magazine writer commented that, unlike previous celebrities' nudes that represented the women's rebellion against repressed society and "trying to tear down" barriers, Kardashian's exhibition was "just provocation and bluster, repeated images that seem to offer us some sort of truth or insight but are really just self serving. We want there to be something more, some reason or context, some great explanation that tells us what it is like to live in this very day and age, but there is not. Kim Kardashian's ass is nothing but an empty promise." However, the stunt "set a new benchmark" in social media response, and Paper's website received 15.9 million views in one day, compared with 25,000 views on an average day.
In June 2014, Kardashian released a mobile game for iPhone and Android called Kim Kardashian: Hollywood. The objective of the game is to become a Hollywood star or starlet. The game supports a free to play model, meaning the game is free to download, but charges for in-game items. The game was a hit, earning US$1.6 million in its first five days of release. In July, the game's developer Glu Mobile announced that the game was the fifth highest earning game in Apple's App Store. Kardashian voiced the role of an alien in an episode of the adult animated series American Dad!, in season 11 (2014–15) in the episode titled "Blagsnarst, A Love Story" on September 21, 2014. In May 2015, Kardashian released a portfolio book called Selfish, a 325-page collection of self-taken photos of herself. In December 2015, Kardashian released an emoji pack for iOS devices called Kimoji. The app was a best-seller, becoming one of the top 5 most bought apps that week. In August 2015, Kardashian was the cover model for Vogue Spain.
In May 2014, Kardashian was estimated to be worth US$45 million. In 2015, Forbes reported she had "made more this year than ever as her earnings nearly doubled to $53 million from 2014's $28 million", and reported that she "has monetized fame better than any other". Much of her income includes wholesale earnings of the Sears line, the Kardashian Kollection, which brought in $600 million in 2013 and the Kardashian Beauty cosmetics line, Kardashian-branded tanning products, the boutique-line DASH, as well as sponsored social media posts which are collectively worth $300,000-500,000 per post. As of July 2018, Kardashian is worth US$350 million. Combined with husband Kanye West's net worth of $1.3 billion, their total household net worth is an estimated $510 million, making them one of the richest couples in the entertainment industry. Kardashian does not receive alimony payments from either of her first two marriages.
