1. Kim Kardashian
Kim K is mostly famous for having sex with Ray J, which is something most people would go to any length to cover up. Since then, she's demonstrated decent business smarts. It's not the first time a celebrity sex tape has launched a career, but it may be the most long-lasting. The bizarre cultural fascination with her family refuses to dissipate, and her marriage to rap producer (and okay yes rapper, but his production is better) Kanye West only keeps her in the spotlight.
2. Paris Hilton
Paris Hilton's rise to fame came when an enterprising romantic partner released an intimate video of the two of them, classily entitled A Night in Paris. The tape became an immediate fascination, due more to the wealth of its co-star than her dead-eyed non-performance. Still, she managed to parlay the infamy into several television and endorsement deals, so she must have some minimum level of business acumen.
3. Perez Hilton
Perez Hilton is a terrible person who's become famous for saying terrible things about other terrible people on a website that looks like it escaped Geocities. When Miley Cyrus stepped out of a car with no underwear on, Perez Hilton plastered the photos all over the Internet, despite the fact that she was a minor at the time. Nobody seems to care about the fact that he is technically a child pornographer.
4. Scott Disick
Scott Disick's fame is a sad ripple in the Ray J Sex Tape pond. He's famous for being the boy-toy of Kourtney Kardashian, who’s famous for being the sister of Kim Kardashian, who in turn is famous for having sex with Ray J on film. He showed flashes of being a clever, devil-may-care foil to the vapid Kardashian krewe, but is ultimately as uninteresting as the rest of them.
5. Farrah Abraham
At some point, MTV abandoned all pretense of being a music television network and became instead a living catalog of sad people. It was shortly after this that they launched the show 16 and Pregnant, proving that there is no life decision so regrettable that it can't be turned into a goldmine. One of the stars of the show, human blow-up doll Farrah Abraham, spun off into Teen Mom with several of the others. Several news outlets continue to indulge in the charade that she matters, covering incidents such as her DUI arrest and her "sex tape" (read: overt pornographic film) with noted adult film star James Deen.
6. Lauren Conrad
We will admit that her clothes are cute and more tasteful than you would expect from a reality star. That doesn't change the fact that they were designed by a person who was famous only by the random winds of fate that granted her a reality show. Still, there's something oddly compelling about The Hills and its predecessor Laguna Beach: The Real Orange County. Both shows nakedly basked in the inherent artifice of the "reality show." The Hills even ended with a now-infamous shot of the set constructed around the show in an apparent indictment of reality TV as a whole. Still, Conrad wouldn't be famous had MTV not randomly chosen to chronicle her life, so here she is.
7. Donald Trump
Let's get one thing clear—Trump is a celebrity, not a businessman. While he may have launched a business with a "small" $1 million loan from his dad, his various businesses have collectively seen four bankruptcies followed by his removal from the board. His wealth is owed largely to his inheritance (his wealth would be about the same today if he'd just put Daddy's money in the bank) and his appearances on reality TV.
8. Nadya Suleman
Many people have turned to fertility assistance and wound up with more than they bargained for, but Nadya Suleman hit the lottery when she gave birth to IVF octuplets in 2009. She hit the news spotlight immediately— because, I mean, who doesn't love babies? But things turned sour when it came out that she was unemployed, on public assistance, and already had six kids. She managed to wrangle a reality show deal that saw each of her children receive $250/day, but still found herself in incredible debt. (A debt that only got worse when she pled no contest to the state of California's accusations of welfare fraud.) In 2014, she starred in a solo adult film that was bizarre and off-putting, even by broad standards set by the world of adult film.
9. The Duggars
Apparently, America loves nothing more than people who don't know when to stop squirting out babies. The stars of 19 Kids and Counting (previously 17 Kids and Counting, but, y'know) are famous for nothing more than prodigious reproduction, lending credence to a lunatic fringe pseudo-Christian sect, and putting Arkansas in the public eye under the auspices of a man named "Jim Bob." The show came under fire recently when human, popped-collar Josh Duggar was revealed as a philanderer with some terrifyingly aggressive sexual tastes—to the surprise of absolutely no-one who was paying attention.
10. "Mama" June Shannon
Noted Jabba-the-Hutt impersonator June Shannon first came into the public eye through a cartwheeling trainwreck of a television program called Toddlers & Tiaras. The show featured six-year-olds engaged in horrific rituals typically associated with human mating while bedecked in layers of spandex and makeup that weighed as much as they did. One of the children—Alana "Honey Boo Boo" Thompson—was deemed charismatic enough for a spin-off that bore her sickeningly infantile pet name. In 2014, the show was canceled when "Mama June" rekindled a relationship with an old flame who happens to be a convicted sex offender who molested her oldest daughter. Somehow, people were shocked that a woman who had been parading her Kindergarten-aged child around under hot lights in lycra for five years would put her selfish whims above her child's basic well-being. Go figure.
