Polaroid 2.0

The PoGo Instant Mobile Printer turns your cellphone camera into a 21st-century Polaroid. Too bad it's already obsolete

2 min read

It’s a nice party trick to pull the new Polaroid PoGo out of your purse and start printing out sticky-backed cellphone pictures. And it’s as easy as can be: To go from staring at a closed package to holding a wallet-size photo of my dog and her new Christmas toy took five minutes.

You pop in the rechargeable lithium-ion battery, plug in the charger, slip a 10-pack of special Zink paper into the printer, turn on your phone’s Bluetooth, wait for it to find the camera, select a picture, hit ”send to,” and choose Bluetooth. Thirty seconds later, your picture emerges. You can also print directly from any digital camera by using a USB connection. With the PoGo, Polaroid brings to digital photography the same instant gratification the company has offered for decades. This time, it’s based on a very different sort of chemistry.

Now that recorded sound has become ubiquitous, we hardly think about it. From our smartphones, smart speakers, TVs, radios, disc players, and car sound systems, it’s an enduring and enjoyable presence in our lives. In 2017, a survey by the polling firm Nielsen suggested that some 90 percent of the U.S. population listens to music regularly and that, on average, they do so 32 hours per week.

Behind this free-flowing pleasure are enormous industries applying technology to the long-standing goal of reproducing sound with the greatest possible realism. From Edison’s phonograph and the horn speakers of the 1880s, successive generations of engineers in pursuit of this ideal invented and exploited countless technologies: triode vacuum tubes, dynamic loudspeakers, magnetic phonograph cartridges, solid-state amplifier circuits in scores of different topologies, electrostatic speakers, optical discs, stereo, and surround sound. And over the past five decades, digital technologies, like audio compression and streaming, have transformed the music industry.
