Mapping the Sneakernet – The New Inquiry
"Digital media travels hand to hand, phone to phone across vast cartographies invisible to Big Data"



"Indeed, the song was just one of many media files I saw on people’s phones: There were Chinese kung fu movies, Nigerian comedies, and Ugandan pop music. They were physically transferred, phone to phone, Bluetooth to Bluetooth, USB stick to USB stick, over hundreds of miles by an informal sneakernet of entertainment media downloaded from the Internet or burned from DVDs, bringing media that’s popular in video halls—basically, small theaters for watching DVDs—to their own villages and huts.

In geographic distribution charts of Carly Rae Jepsen’s virality, you’d be hard pressed to find impressions from this part of the world. Nor is this sneakernet practice unique to the region. On the other end of continent, in Mali, music researcher Christopher Kirkley has documented a music trade using Bluetooth transfers that is similar to what I saw in northern Uganda. These forms of data transfer and access, though quite common, are invisible to traditional measures of connectivity and Big Data research methods. Like millions around the world with direct internet connections, young people in “unconnected” regions are participating in the great viral products of the Internet, consuming mass media files and generating and transferring their own media.

Indeed, the practice of sneakernets is global, with political consequences in countries that try to curtail Internet access. In China, I saw many activists trading media files via USB sticks to avoid stringent censorship and surveillance. As Cuba opens its borders to the world, some might be surprised that citizens have long been able to watch the latest hits from United States, as this Guardian article notes. Sneakernets also apparently extend into North Korea, where strict government policy means only a small elite have access to any sort of connectivity. According to news reports, Chinese bootleggers and South Korean democracy activists regularly smuggle media on USB sticks and DVDs across the border, which may be contributing to increasing defections, as North Korean citizens come to see how the outside world lives.

Blum imagines the Internet as a series of rivers of data crisscrossing the globe. I find it a lovely visual image whose metaphor should be extended further. Like water, the Internet is vast, familiar and seemingly ubiquitous but with extremes of unequal access. Some people have clean, unfettered and flowing data from invisible but reliable sources. Many more experience polluted and flaky sources, and they have to combine patience and filters to get the right set of data they need. Others must hike dozens of miles of paved and dirt roads to access the Internet like water from a well, ferrying it back in fits and spurts when the opportunity arises. And yet more get trickles of data here and there from friends and family, in the form of printouts, a song played on a phone’s speaker, an interesting status update from Facebook relayed orally, a radio station that features stories from the Internet.

Like water from a river, data from the Internet can be scooped up and irrigated and splashed around in novel ways. Whether it’s north of the Nile in Uganda or south of Market St. in the Bay Area, policies and strategies for connecting the “unconnected” should take into account the vast spectrum of ways that people find and access data. Packets of information can be distributed via SMS and mobile 3G but also pieces of paper, USB sticks and Bluetooth. Solar-powered computer kiosks in rural areas can have simple capabilities for connecting to mobile phones’ SD cards for upload and download. Technology training courses can start with a more nuanced base level of understanding, rather than assuming zero knowledge of the basics of computing and network transfer. These are broad strokes, of course; the specifics of motivation and methods are complex and need to be studied carefully in any given instance. But the very channels that ferry entertainment media can also ferry health care information, educational material and anything else in compact enough form.

There are many maps for the world’s internet tubes and the electric wires that power them, but, like any map, they reflect an inherent bias, in this case toward a single user, binary view of connectivity. This view in turn limits our understanding of just how broad an impact the Internet has had on the world, with social, political and cultural implications that have yet to be fully explored. One critical addition to understanding the internet’s global impact is mapping the many sneakernets that crisscross the “unconnected” parts of the world. The next billion, we might find, are already navigating new cities with Google Maps, trading Korean soaps and Nigerian comedies, and rocking out to the latest hits from Carly Rae Jepsen."
