Losing the Signal is a riveting story of a company that toppled global giants before succumbing to the ruthlessly competitive forces of Silicon Valley. This is not a conventional tale of modern business failure by fraud and greed. The rise and fall of BlackBerry reveals the dangerous speed at which innovators race along the information superhighway.
With unprecedented access to key players, senior executives, directors and competitors, Losing the Signal unveils the remarkable rise of a company that started above a bagel store in Ontario. At the heart of the story is an unlikely partnership between a visionary engineer, Mike Lazaridis, and an abrasive Harvard Business school grad, Jim Balsillie. Together, they engineered a pioneering pocket email device that became the tool of choice for presidents and CEOs. The partnership enjoyed only a brief moment on top of the world, however. At the very moment BlackBerry was ranked the world's fastest growing company internal feuds and chaotic growth crippled the company as it faced its gravest test: Apple and Google's entry in to mobile phones.
Expertly told by acclaimed journalists, Jacquie McNish and Sean Silcoff, this is an entertaining, whirlwind narrative that goes behind the scenes to reveal one of the most compelling business stories of the new century.
—Tom Vanderbilt, New York Times bestselling author of Traffic

For the first time in history, the tools for cooperating on a global scale are not solely in the hands of governments or institutions. The spread of the internet and mobile phones are changing how people come together and get things done—and sparking a revolution that, as Clay Shirky shows, is changing what we do, how we do it, and even who we are. Here, we encounter a whoman who loses her phone and recruits an army of volunteers to get it back from the person who stole it. A dissatisfied airline passenger who spawns a national movement by taking her case to the web. And a handful of kids in Belarus who create a political protest that the state is powerless to stop. Here Comes Everybody is a revelatory examination of how the wildfirelike spread of new forms of social interaction enabled by technology is changing the way humans form groups and exist within them. A revolution in social organization has commenced, and Clay Shirky is its brilliant chronicler.
"Drawing from anthropology, economic theory and keen observation, [Shirky] makes a strong case that new communication tools are making once-impossible forms of group action possible . . . [an] extraordinarily perceptive new book." -Minneapolis Star Tribune
"Mr. Shirky writes cleanly and convincingly about the intersection of technological innovation and social change." -New York Observer

In his bestselling Here Comes Everybody, Internet guru Clay Shirky provided readers with a much-needed primer for the digital age. Now, with Cognitive Surplus, he reveals how new digital technology is unleashing a torrent of creative production that will transform our world. For the first time, people are embracing new media that allow them to pool their efforts at vanishingly low cost. The results of this aggregated effort range from mind-expanding reference tools like Wikipedia to life-saving Web sites like Ushahidi.com, which allows Kenyans to report acts of violence in real time. Cognitive Surplus explores what's possible when people unite to use their intellect, energy, and time for the greater good.
In December 2009, Google began customizing its search results for each user. Instead of giving you the most broadly popular result, Google now tries to predict what you are most likely to click on. According to MoveOn.org board president Eli Pariser, Google's change in policy is symptomatic of the most significant shift to take place on the Web in recent years-the rise of personalization. In this groundbreaking investigation of the new hidden Web, Pariser uncovers how this growing trend threatens to control how we consume and share information as a society-and reveals what we can do about it.
Though the phenomenon has gone largely undetected until now, personalized filters are sweeping the Web, creating individual universes of information for each of us. Facebook-the primary news source for an increasing number of Americans-prioritizes the links it believes will appeal to you so that if you are a liberal, you can expect to see only progressive links. Even an old-media bastion like The Washington Post devotes the top of its home page to a news feed with the links your Facebook friends are sharing. Behind the scenes a burgeoning industry of data companies is tracking your personal information to sell to advertisers, from your political leanings to the color you painted your living room to the hiking boots you just browsed on Zappos.
In a personalized world, we will increasingly be typed and fed only news that is pleasant, familiar, and confirms our beliefs-and because these filters are invisible, we won't know what is being hidden from us. Our past interests will determine what we are exposed to in the future, leaving less room for the unexpected encounters that spark creativity, innovation, and the democratic exchange of ideas.
While we all worry that the Internet is eroding privacy or shrinking our attention spans, Pariser uncovers a more pernicious and far- reaching trend on the Internet and shows how we can- and must-change course. With vivid detail and remarkable scope, The Filter Bubble reveals how personalization undermines the Internet's original purpose as an open platform for the spread of ideas and could leave us all in an isolated, echoing world.
That time-honored trope: the notion that technology is not the problem, rather, it’s how people use technology that’s the problem is shown to be wanting. Highlighting Marshall McLuhan’s “tetrads” or laws of media as a primary tool of analysis, R.C. MacDougall argues in line with other media ecologists that it’s not so much how we use certain tools that matters, it’s that we use them. More than any other technological form perhaps, communication technologies play particularly powerful and systemic roles in our culture, or any culture for that matter. Late adopters and even abstainers are not exempt from the psychological, social and cultural effects (and side-effects) of modern digital communication technology. While there are certainly varying degrees of immersion –that is to say, while some of us live in the high-rise downtown district, some at the city limits, and still others out in the proverbial “woods”– we all live in Digination today.
Reinventing Discovery tells the exciting story of an unprecedented new era of networked science. We learn, for example, how mathematicians in the Polymath Project are spontaneously coming together to collaborate online, tackling and rapidly demolishing previously unsolved problems. We learn how 250,000 amateur astronomers are working together in a project called Galaxy Zoo to understand the large-scale structure of the Universe, and how they are making astonishing discoveries, including an entirely new kind of galaxy. These efforts are just a small part of the larger story told in this book--the story of how scientists are using the internet to dramatically expand our problem-solving ability and increase our combined brainpower.
This is a book for anyone who wants to understand how the online world is revolutionizing scientific discovery today--and why the revolution is just beginning.
Spreadable Media is a rare inside look at today’s ever-changing media landscape. The days of corporate control over media content and its distribution have been replaced by the age of what the digital media industries have called “user-generated content.” Spreadable Media maps these fundamental changes, and gives readers a comprehensive look into the rise of participatory culture, from internet memes to presidential tweets.
The authors challenge our notions of what goes “viral” and how by examining factors such as the nature of audience engagement and the environment of participation, and by contrasting the concepts of “stickiness”—aggregating attention in centralized places—with “spreadability”—dispersing content widely through both formal and informal networks. The former has often been the measure of media success in the online world, but the latter describes the actual ways content travels through social media. The book explores the internal tensions businesses face as they adapt to this new, spreadable, communication reality and argues for the need to shift from “hearing” to “listening” in corporate culture.
Now with a new afterword addressing changes in the media industry, audience participation, and political reporting, and drawing on modern examples from online activism campaigns, film, music, television, advertising, and social media—from both the U.S. and around the world—the authors illustrate the contours of our current media environment. For all of us who actively create and share content, Spreadable Media provides a clear understanding of how people are spreading ideas and the implications these activities have for business, politics, and everyday life, both on- and offline.
Additional highlights include:
- Fundamental information on communications, signal and system theories
