Book Description
This book focuses on the history of the International Telecommunication Union (ITU), from its origins in the mid-19th century to nowadays. ITU was the first international organization ever and still plays a crucial role in managing global telecommunications today. Putting together some of the most relevant scholars in the field of transnational communications, the book covers the history of ITU from 1865 to digital times in a truly global perspective, taking into account several technologies like the telegraph, the telephone, cables, wireless, radio, television, satellites, mobile phone, the internet and others. The main goal is to identify the long-term strategies of regulation and the techno-diplomatic manoeuvres taken inside ITU, from convincing the majority of the nations to establish the official seat of the Telegraph Union bureau in Switzerland in the 1860s, to contrasting the multi-stakeholder model of Internet governance (supported by US and ICANN). History of the International Telecommunication Union is a trans-disciplinary text and can be interesting for scholars and students in the fields of telecommunications, media, international organizations, transnational communication, diplomacy, political economy of communication, STS, and others. It has the ambition to become a reference point in the history of ITU and, at the same time, just the fi rst comprehensive step towards a longer, inter-technological, political and cultural history of transnational communications to be written in the future.

Book Description
A Library Journal Best Book of 2015 A NPR Great Read of 2015 The Internet in Russia is either the most efficient totalitarian tool or the device by which totalitarianism will be overthrown. Perhaps both. On the eighth floor of an ordinary-looking building in an otherwise residential district of southwest Moscow, in a room occupied by the Federal Security Service (FSB), is a box the size of a VHS player marked SORM. The Russian government's front line in the battle for the future of the Internet, SORM is the world's most intrusive listening device, monitoring e-mails, Internet usage, Skype, and all social networks. But for every hacker subcontracted by the FSB to interfere with Russia's antagonists abroad -- such as those who, in a massive denial-of-service attack, overwhelmed the entire Internet in neighboring Estonia -- there is a radical or an opportunist who is using the web to chip away at the power of the state at home. Drawing from scores of interviews personally conducted with numerous prominent officials in the Ministry of Communications and web-savvy activists challenging the state, Andrei Soldatov and Irina Borogan peel back the history of advanced surveillance systems in Russia. From research laboratories in Soviet-era labor camps, to the legalization of government monitoring of all telephone and Internet communications in the 1990s, to the present day, their incisive and alarming investigation into the Kremlin's massive online-surveillance state exposes just how easily a free global exchange can be coerced into becoming a tool of repression and geopolitical warfare. Dissidents, oligarchs, and some of the world's most dangerous hackers collide in the uniquely Russian virtual world of The Red Web.
