Top 10 Non-Musical One-Hit Wonders
Every field has its Rick Astley.
Musical one-hit wonders are forever trying to become two-hit wonders, struggling to impress fans.
See the Baha Men, Billy Ray Cyrus and Biz Markie. Every one-hit wonder sees him- or herself as a potential superstar in the music world, but the wunderkinds in other fields know when to take a step back and just enjoy the success.
1. Tom Anderson

Tom from Myspace has literally done NOTHING since he sold Myspace in 2005. He's worth $580 million, so he doesn't have to do anything if he doesn't want to (though apparently he TRIED to be a photographer at Burning Man).
2. Gary Dahl

Inventor of the pet rock toy, Dahl made nearly $15 million off of the 6-month fad. After his hit, he just continued to have a happy rich-dude life and started his own ad agency.
3. Markus Persson

Persson created "Minecraft" and then sold it for $2.5 billion to Microsoft. However, post-hit life hasn't been that great for Persson because he keeps tweeting about feeling lonely.
4. Anna Sewell

Sewell wrote "Black Beauty," that really cute book about horses and animal rights that everyone reads in, like, third grade. She never wrote another book (because she died right after "Black Beauty" was published).
5. Dong Nguyen

Nguyen created the notoriously viral game "Flappy Bird" and then deleted it because so many people were hating on him for making such a difficult game. Although Flappy Bird was literally the hardest game ever, Nguyen was making almost $50,000 per DAY. Since then, Nguyen's been developing other mobile games and none of them have done as well as "Flappy Bird."
6. Xavier Roberts

Roberts created the Cabbage Patch kids using his knowledge of sewing and soft sculpture, and they were such a great hit that he just stuck with it. The dolls hit their peak in the 80s, but they are still popular today. The dolls have made him over $100 million.
7. Joseph T. Listner

Listner invented the automated machine that cuts carrots into baby carrots and carrot sticks. He never sold the rights to the machine or the company because he didn't want a company to abuse the quality of the carrots. He kept trying to invent things in his old age, but never any as successful as the automated carrot slicer.
8. Dave Kapell

Those magnetic word sets you buy for your mom when you forget to give her a birthday present? Dave Kapell invented those because he used to cut the words out of his diary entries and try to scramble them into a song. From there, Magnetic Poetry was born and, like Xavier Roberts, Kapell just stuck with putting words on magnets and it's been very successful.
9. Edward Craven Walker

Walker invented the lava lamp (originally called the astra lamp) and it was a defining must-have item of the 60s. Most of Walker's success was due to his slogan: "If you buy my lamp, you won't need drugs." That tagline made the lamp popular with hippies and non-hippies alike.
10. The Wright Brothers

The Wright Brothers may be famous but that doesn't change their one-hit wonder status. They never changed up their model much and were so obsessed with their one style of plane that they got caught in a huge patent war with the U.S. government, which ended their patent in order to build planes for World War I. The brothers tried their hand at some other inventions but none of them took off like the airplane.
