Every year, TIME highlights inventions that are making the world better, smarter and even a bit more fun. (See last year’s list here.) To assemble our 2020 list, we solicited nominations both from our editors and correspondents around the world, and through an online application process. We then evaluated each contender on key factors, including originality, creativity, effectiveness, ambition and impact.
