Microwaves
When microwaves first hit the scene, they were called “cavity magnetrons”. This wasn’t exactly a marketable title, and we can’t see that this modern miracle would be as popular as it is today without going through a bit of a rebrand first. The microwave revolutionized homes all over the world, and after twenty copies of early prototypes were used in WWII for various means, including signaling early attack to troops somehow, it made its way into the mainstream with a full force not long after.
