It used to be that a tinkerer like Misterovich could, at best, hope to sell his idea to a big company. More likely, he’d entertain friends with his Pez-sized visions. But a number of factors are coming together to empower amateurs in a way never before possible, blurring the lines between those who make and those who take. Unlike the dot-com fortune hunters of the late 1990s, these do-it-yourselfers aren’t deluding themselves with oversized visions of what they might achieve. Instead, they’re simply finding a way—in this mass-produced, Wal-Mart world—to take power back, prove that they can make the products that they want to consume, have fun doing so, and, just maybe, make a few dollars. “What’s happened is a tremendous change in awareness,” says Eric von Hippel, a professor at the MIT Sloan School of Management and author of the recent Democratizing Innovation. “Conventional wisdom is so strong [in business] about find-a-need-and-fill-it: ‘We’re the manufacturers; we design products; we ask users what they need; we do it.’ That has begun to crack.”
