Discourse and interest in the digital divide research community is steadily shifting beyond access and adoption to utilization, impact, and outcomes of information and communications technologies (ICTs), particularly the internet. In the United States, studies and surveys conducted by the National Telecommunications and Information Administration (NTIA) indicate increase in internet use in every corner of the country over the last two decades. However, recent surveys on ICT use indicate significant disparities in dimensions of internet use. For example Americans’ use of the internet to pursue e-education, e-health, e-commerce, e-entertainment, and telecommuting has varied significantly – longitudinally as well as geographically. Additionally, internet use habits are rapidly expanding, providing new insights into the emerging internet of things, wearable technologies, and new forms of social media usage. As novel technologies and lifestyles emerge, analysis of new disparities and dimensions of the “usage digital divide” stemming from social, economic, societal, and environmental factors becomes important. This research examines spatial clusters, geographic disparities, and socio-economic dimensions of existing and emerging dimensions of internet use among the 50 U.S. states.

A new study in the American Economic Review, with an intriguing and persuasive methodology, finds that Fox News could influence how Americans vote, perhaps even tipping elections. Emory University political scientist Gregory Martin and Stanford economist Ali Yurukoglu estimate that watching Fox News directly causes a substantial rightward shift in viewers’ attitudes, which translates into a significantly greater willingness to vote for Republican candidates. They estimate that if Fox News hadn't existed, the Republican presidential candidate’s share of the two-party vote would have been 3.59 points lower in 2004 and 6.34 points lower in 2008. For context, that would've made John Kerry the 2004 popular vote winner, and turned Barack Obama's 2008 victory into a landslide where he got 60 percent of the two-party vote. "There is a non-trivial amount of uncertainty" about those estimates, Yurukoglu cautions. "I personally don't think it's totally implausible, but it is higher than I would have guessed prior to the research." And even if the effect were half as large as estimated, that’d still mean that Fox News is having a very real, sizable effect on elections.

[Commentary] The three of us investigated several of the most promising efforts to “re-decentralize” the web, to better understand their potential to shake up the dominance of Facebook, Google, and Twitter. The projects we examined are pursuing deeply exciting new ideas. However, we doubt that decentralized systems alone will address the threats to free expression caused by today’s mega-platforms, for several key reasons. First, these tools will face challenges acquiring users and gaining the attention of developers. These platforms also pose new security threats. Social media platforms are curators, not just publishers. Finally, platforms benefit from economies of scale — it’s cheaper to acquire resources like storage and bandwidth in bulk. And with network effects, which make larger platforms more useful, you have a recipe for consolidation.

T-Moble and Verizon Wireless were the two big winners of the 2017 U.S. Market Report by Ookla, which measures broadband performance for wireless networks. Overall, Ookla’s data found that U.S. mobile broadband download speeds have increased by 19% during the past year to reach 22.69 Mbps. Rural mobile broadband speeds lag the national average. The speed scores assess performance for both upload and download speeds. Average upload speeds increased slightly to 8.51 Mbps, a 4% improvement.

Percentage improvements in both download and upload speeds were smaller than in previous years. U.S. global rankings slipped as a result, with the U.S. now ranked 44th globally, down from 42nd for Q1-Q2 2017. Ookla found an average rural mobile broadband speeds of 17.93 Mbps, which is 20.9% slower than the national average. This translates into an ASR of 69.6% in rural service areas (RSAs) compared to a national ASR average of 74.9%. Metropolitan service areas had an ASR of 76.2%.

Sept 8, three research papers using National Telecommunications & Information Administration's Digital Nation survey data will be presented at the 45th Research Conference on Communications, Information and Internet Policy (TPRC) an annual conference attended by researchers, policymakers, and advocates from the public, academic, and private sectors. The papers serve as instructive examples of how researchers can take NTIA's survey data beyond the basic metrics to offer unique and valuable insights into Internet use in America. Policy staff from NTIA will present one of the papers, which examines the connection between digital and financial inclusion. Another paper - a TPRC Student Paper Contest winner - comes from a student from Oklahoma State University Stillwater who wrote about the behavioral relationships behind the increases in mobile-only households. And researchers from the University of Redlands School of Business used NTIA data to examine geographic patterns of Internet use in U.S. states.

[Commentary] What does gigabit civic engagement look like? The initial winners of the Charles Benton Next Generation Engagement Award demonstrate not just what “could be” but what “is”. Civic engagement is about working to make a positive difference in the life of our communities. It is about developing the combination of knowledge, skills, values, and motivation to make that difference. It means improving the quality of life in a community, through both political and non-political processes. An engaged individual recognizes himself or herself as a member of the larger social fabric and, therefore, considers social problems to be at least partly his or her own. Such an individual is willing to see the community-wide dimensions of issues, to make and justify informed decisions, and to take action for the benefit of the community. My father spent a lifetime advocating for a holistic approach combining access to fast, fair, and open communications networks and the training to develop 21st century skills. He undoubtedly would have been extremely proud that his name is attached to this award and to the project winners in Louisville, Kentucky; Austin, Texas; and Raleigh, North Carolina.

Chicago and California are the United States’ top Gigabit city and state, according to research from telecom equipment maker VIAVI.

The data comes from the VIAVI Solutions Gigabit Monitor database and is summarized in a report titled “The State of US Gigabit Deployments.” VIAVI – formerly JDSU – found that Gigabit services are available to more than 8.5 million people in California and more than 6 million people in Chicago. The rest of the top ten states are Illinois (about 6.5 million), Colorado (5.2 million), Georgia (4.2 million), Florida (3.4 million), Utah (2.4 million), New York (2 million), Tennessee (2 million), Texas (1.2 million) and Michigan (976,000). On the city list, Chicago is followed by Atlanta (about 3.8 million), Denver (2.3 million) New York (2 million), Nashville (1.26 million), San Francisco (1.2 million), San Jose (1.1 million), Detroit (922,000), Fresno (586,000) and Chattanooga (506,000).

Fixed broadband speeds are getting faster, thanks to infrastructure upgrades that are allowing internet service providers to offer faster and cheaper packages. The average US fixed broadband download speed was 64.17 Mbps (15th in the world) in the first half of 2017, while the average upload speed was 22.79 Mbps (24th in the world), according to data released from internet speed test company Ookla. That’s up from a 54.97 Mbps download speed and an upload speed of 18.88 Mbps in 2016. For this report, Ookla measured internet speeds from 111 million tests initiated by 26 million unique users. Of the ISPs, Comcast’s Xfinity had the fastest national Speed Score — a single metric that factors in low-end, median and top performance for upload and download rates across a carrier’s network — while CenturyLink had the slowest.

Mapping analyses of AT&T’s 2016 broadband deployment data reported to the Federal Communications Commission for Wayne County, MI, (Detroit) and Lucas County, OH, (Toledo) show the same pattern of “digital redlining” of low income neighborhoods as National Digital Inclusion Alliance research has previously revealed in the Cleveland and Dayton areas.

The new maps, showing Census blocks in the two counties where AT&T offers fast fiber-enhanced “VDSL” broadband service — and blocks where it doesn’t — are part of NDIA’s ongoing research into the FCC’s Form 477 Fixed Broadband Deployment data for June 2016. NDIA has found a high correlation between neighborhoods where AT&T has chosen not to deploy the newer fiber-to-the-neighborhood technology, and those with poverty rates of 35 percent or more. In areas where the company hasn’t installed VDSL capacity, households as well as small businesses are still dependent on older, slower, all-copper ADSL2 service with maximum downloads speeds as low as 1.5 mbps or even 768 kbps.

It’s easy to get fixated on all the “smart” innovations out there—roads that talk to you, cars that talk to the road, and all kinds of sensors. But if it’s not the gadget that makes a city smart, then what does?

The heart of a smart city is actually the data and the brain is using that data to change your decision-making process, to make you react faster in cases where the city needs to react, to make you predictive where you can be to save money or provide a better service, or to give you a better appreciation of what's happening in your city. 85 percent of the data that you need to run a smart city, you’ve probably already got. Any city can be a smart city, or a smarter city, just by getting better control of their data and by understanding what it's saying to them. And it's going to say something different to every city, because every city has different needs and requirements, and different governance structures.
