TIME has officially opened the submission process for our 2019 edition of Best Inventions.

This annual list is dedicated to recognizing the Best Inventions making the world better, smarter, and even a bit more fun—everything from diet-friendly ice cream to groundbreaking gadgets. It’s also one of TIME’s biggest editorial franchises, garnering some 250 million media impressions each year, in addition to coverage in TIME Magazine (18 million weekly readers) and on TIME.com (32.5 million monthly unique visitors).

This year, in order to recognize even more Best Inventions, they are doubling the size of the list from 50 to 100 inventions, as well as expanding the number of categories it covers. If you are working on something that might fit the bill, you may want to consider submitting it here. They even have an experimental category for inventions that are still in the prototype or conceptual phase.

June 1, 2019 – July 14, 2019
