Editor’s Note: Eric Tyler is a Program Associate for the Global Assets Project at the New America Foundation. This post is part of the Global Innovation Showcase created by the New America Foundation and the Global Public Square. By Eric Tyler - Special to CNN Last April, M.I.T. held a business conference on campus titled “Africa 2.0: Achieving Growth Through Innovation.” In the keynote speech, Dr. When it comes to the discussion of emerging markets, the conversation is normally dominated by talk of China, India and Brazil. The International Monetary Fund forecasts that in the next five years, Africa will have seven out of the ten fastest-growing economies in the world. In the past five years, the information and communication technology sector in Sub-Saharan Africa experienced an annual compounded growth rate of 40%, the fastest globally.
Tech-inspired entrepreneurs and businesses are innovating to keep up with growing demands and needs of Africa’s increasingly tech-enabled markets. The Political Relevance of the Internet in Developing Countries. More often than not, the number one skepticism I hear from academics regarding Internet use in developing countries is their incredulity regarding individuals’ desire to consume political information online. This is commonly followed by their conjecture that it seems much more likely that these individuals are using the Internet for porn, video games, or watching silly cat videos on Youtube. Although there is undoubtedly a fair degree of Internet use toward these ends, the belief that individuals in developing countries would not have any desire at all to use the Internet to seek out political information dumbfounds me.
Instead, I attribute this disbelief to a lack of perspective. In developed nations, we have long been inundated with information, particularly political information. Perhaps, I am also fortunate to have been in countries, through my research, where I witnessed firsthand the sincere desire for political information among average citizens. Global mobile phone ownership: the haves and have-nots by region - Gadgets & Tech, Life & Style. An infograph put together by mobile maker Nokia with recently released data from the International Telecommunications Union shows the mobile ownership divide around the globe. In Europe, mobile ownership is high with 13 mobiles for every ten people (or one mobile phone subscription for every 0.8 people). "Once you take away the very young and the very old from the equation, that means a very large number of people with either two phones, or a data dongle, or a GPS-system that requires a SIM, or maybe tablet computers," said Nokia in a March 29 blog post.
It's a very different story in Africa; for every ten people there are only around 4 phones which equates to around one SIM subscription for every 2.4 people. However, the aggregated data paints a somewhat rosy picture of the mobile phone distribution throughout the country. According to the World Bank's World Development Indicators, 60.84 percent of the world's total population had a mobile phone subscription in 2008. The data behind The Real Life Social Network – Are you thinking inside out?
Many people have asked me about some of the references for my Real Life Social Network talk . So here they are. I’m truly standing on the shoulders of others.

This first-of-its-kind study, which was partially funded by CIRCLE, examined three types of behavior: politically-driven online participation, online exposure to diverse perspectives, and interest-driven online participation. Youth who pursue their interest on the Internet are more likely to be engaged in civic and political issues, according to the study of student Internet usage authored by Joe Kahne, education professor at Mills College and CIRCLE Advisory Board member.

Global Publics Embrace Social Networking. Computer and Cell Phone Usage Up Around the World Although still a relatively young technology, social networking is already a global phenomenon. In regions around the world – and in countries with varying levels of economic development – people who use the internet are using it for social networking.
And this is particularly true of young people. Meanwhile, other forms of technology are also increasingly popular across the globe. Cell phone ownership and computer usage have grown significantly over the last three years, and they have risen dramatically since 2002. While social networking has spread globally, it is particularly widespread in the country where it began. Among the 22 publics surveyed, Americans most often say they use websites like Facebook and MySpace: 46% use such sites; 36% use the internet, but do not access these sites; and 18% say they never go online.
Among the 22 countries polled, social networking is least prevalent in Indonesia (6%) and Pakistan (3%).
