"The world is going mobile at an astounding pace. Estimates show 80 percent of global Internet access will take place through mobile devices by 2016. Smartphones, tablets, and handheld devices have reshaped communications, the global economy, and the very way in which we live. The revolution is an electronic nirvana: for the first time in human history we have sophisticated digital applications to help us learn, access financial and health care records, connect with others, and build businesses. But the one trillion dollar mobile industry is still relatively young. Leaders in both the public and private sectors need to figure out how to apply mobile technologies or mobile devices to optimize education, health care, public safety, disaster preparedness, and economic development. And the ever-expanding mobile frontier presents new challenges to law, policy, and regulations and introduces new tensions; one person's idea of cautious deliberation can be another's idea of a barrier to innovation. In Going Mobile, Darrell M. West breaks down the mobile revolution and shows how to maximize its overall benefits in both developed and emerging markets. Contents 1.

The Federal Trade Commission (FTC) has worked on privacy issues for over forty years, and in 2000 began considering the privacy implications raised by consumers' growing use of mobile devices. More recently, the FTC hosted a mobile privacy panel discussion that focused on transparency. With so many players collecting and using consumer data, who should provide privacy information to consumers? Given the limited screen space of mobile devices, how can this information be conveyed? This book explores and offers suggestions for the major participants in the mobile ecosystem as they work to improve mobile privacy disclosures.

Mobile devices, once associated only with voice telephone service, have become the launching pads for new data-driven technologies and services. Today, consumers use their mobile devices for myriad purposes including "chatting" through text messaging, taking pictures, browsing the Web, making purchases, listening to music, viewing videos, playing games across cyberspace, and keeping track of friends and relatives. This book addressed the mobile marketplace in the U.S., including the contours of the mobile market place and factors affecting the adoption of new mobile applications. Furthermore, in November 2001, wireless service providers began to connect their networks for text messaging, allowing subscribers on different networks to exchange text messages. Since then, the number of text messages in the U.S. has grown to over 48 billion messages every month. In this book, the discussion of the current mobile market in the U.S. was focused on three general areas: 1) text messaging; 2) ringtones and ringbacks; and 3)Internet access, mobile television, and new and emerging services.

Providing video companionship for isolated housewives, afternoon babysitting for children, and nonstop evening entertainment for the whole family, television revolutionized American society in the post-World War II years. Helping the first TV generation make sense of the new medium was the mission of Jack Gould, television critic of The New York Times from 1947 to 1972. In columns noteworthy for crisp writing, pointed insights, and fair judgment, he highlighted both the untapped possibilities and the imminent perils of television, becoming "the conscience of the industry" for many people.

In this book, historian Lewis L. Gould, Jack Gould's son, collects over seventy of his father's best columns. Grouped topically, they cover a wide range of issues, including the Golden Age of television drama, McCarthy-era blacklisting, the rise and fall of Edward R. Murrow, quiz show scandals, children's programming, and the impact of television on American life and of television criticism on the medium itself. Lewis Gould also supplies a brief biography of his father that assesses his influence on the evolution of television, as well as prefaces to each section.

In 1876, Alexander Graham Bell uttered the words that would inaugurate a new era in human communication: 'Mr. Watson, come here, I want to see you'. Bell was speaking through his new invention: the telephone. Though his name is the first to be associated with this now ubiquitous device, Bell was not working in a vacuum or entirely on his own. The second half of the 19th century was a time of great innovation, during which many people were experimenting with various designs for machines to enable human communication over great distances. Bell was simply the first to win a patent. ""Alexander Graham Bell and the Telephone"" tells the story of the man who invented the telephone, the people who helped him, and the changes that came about because of one of the greatest inventions of all time.

The message of this book is simple: the mobile phone strengthens social bonds among family and friends. With a traditional land-line telephone, we place calls to a location and ask hopefully if someone is "there"; with a mobile phone, we have instant and perpetual access to friends and family regardless of where they are. But when we are engaged in these intimate conversations with absent friends, what happens to our relationship with the people who are actually in the same room with us? In New Tech, New Ties, Rich Ling examines how the mobile telephone affects both kinds of interactions--those mediated by mobile communication and those that are face to face. Ling finds that through the use of various social rituals the mobile telephone strengthens social ties within the circle of friends and family--sometimes at the expense of interaction with those who are physically present--and creates what he calls "bounded solidarity." Ling argues that mobile communication helps to engender and develop social cohesion within the family and the peer group. Drawing on the work of Emile Durkheim, Erving Goffman, and Randall Collins, Ling shows that ritual interaction is a catalyst for the development of social bonding. From this perspective, he examines how mobile communication affects face-to-face ritual situations and how ritual is used in interaction mediated by mobile communication. He looks at the evidence, including interviews and observations from around the world, that documents the effect of mobile communication on social bonding and also examines some of the other possibly problematic issues raised by tighter social cohesion in small groups.Rich Ling is Senior Researcher at the Norwegian telecommunications company Telenor and Adjunct Research Scientist at the University of Michigan. He is the author of The Mobile Connection: The Cell Phone's Impact on Society.
