Think of the gear you can’t live without: The smartphone you constantly check. The camera that goes with you on every vacation. The TV that serves as a portal to binge-watching and -gaming. Each owes its influence to one model that changed the course of technology for good. It’s those devices we’re recognizing in this list of the 50 most influential gadgets of all time. Some of these, like Sony’s Walkman, were the first of their kind. Others, such as the iPod, propelled an existing idea into the mainstream. Some were unsuccessful commercially, but influential nonetheless. And a few represent exciting but unproven new concepts (looking at you Oculus Rift). Rather than rank technologies—writing, electricity, and so on—we chose to rank gadgets, the devices by with consumers let the future creep into their present. The list—which is ordered by influence—was assembled and deliberated on at (extreme) length by TIME’s technology and business editors, writers and reporters. What did we miss?
Google Glass, which cost $1,500 for those invited to a sort of public beta test, never took off. The relatively powerful head-mounted computer provided important signals for the future of wearable technology. Glass showed that designers working on computing devices that are worn face a different set of assumptions and challenges. Glass, for example, made it easy for users to surreptitiously record video, which led some restaurants, bars and movie theaters to ban the device. Glass also showed the potential pitfalls of easily identifiable wearables, perhaps best proven by the coining of the term “Glassholes” for its early adopters. While Glass was officially shelved in 2015, augmented reality—displaying computer-generated images over the real world—is a concept many companies are still trying to perfect. Google included.
The Makerbot Replicator was neither the first nor the best consumer-level 3-D printer. But it was the model that made the technology widely accessible for the first time, thanks to its sub-$2,000 price tag. The Replicator used inkjet printer-like technology to extrude hot plastic that took three-dimensional form as artwork, mechanical parts and more. As a company, Makerbot’s future is uncertain. But the firm’s equipment helped bring 3-D printing into the mainstream and is a fixture of many American classrooms.
Yamaha Clavinova Digital Piano
You could argue the Minimoog did far more for music tech, or that the Fairlight was cooler, but visit average U.S. households from the 1980s forward and you’re most likely to encounter the Clavinova. Yamaha’s popular digital piano married the look and compactness of a spinet (a smaller, shorter upright piano) with the modern qualities of a modest synthesizer. With a plausibly pianistic weighted action and space-saving footprint, it’s become a staple for parents looking to bring maintenance-free musicality—you never have to tune it—into households, all without sacrificing huge swathes of living space.
Small drones may soon be delivering our packages, recording our family get-togethers and helping first responders find people trapped in a disaster. For now, they’re largely playthings for hobbyists and videographers. Chinese firm DJI makes the world’s most popular, the Phantom lineup. Its latest iteration, the Phantom 4, uses so-called computer vision to see and avoid obstacles without human intervention. That makes it easier for rookie pilots to fly one, making drones more accessible than ever.
The Raspberry Pi is a single-board computer with a price tag to match its tiny size: about $35, without a monitor, mouse or keyboard. Not meant to replace everyday computers, the Pi is being used in classrooms worldwide to help students learn programming skills. With eight million Pi’s sold as of last year, the odds are decent that the next Mark Zuckerberg will have gotten his or her start tinkering with one.
