A Truck Full of Money: One Man's Quest to Recover from Great Success

by Tracy Kidder

"A perfectly executed, exquisitely reported parable of the Internet age and the wild, mad adventure that is start-up culture."--Charles Duhigg Fortune, mania, genius, philanthropy--the bestselling author of Mountains Beyond Mountains gives us the inspiring story of Paul English, the founder of Kayak.com and Lola. Tracy Kidder, the "master of the nonfiction narrative" (The Baltimore Sun) and author of the bestselling classic The Soul of a New Machine, now tells the story of Paul English, a kinetic and unconventional inventor and entrepreneur, who as a boy rebelled against authority. Growing up in working-class Boston, English discovers a medium for his talents the first time he sees a computer. As a young man, despite suffering from what would eventually be diagnosed as bipolar disorder, he begins his pilgrim's journey through the ups and downs in the brave new world of computers. Relating to the Internet as if it's an extension of his own mind, he discovers that he has a talent for conceiving innovative enterprises and building teams that can develop them, becoming "a Pied Piper" of geeks. His innovative management style, success, and innate sense of fair play inspire intense loyalty. Early on, one colleague observes: "Someday this boy's going to get hit by a truck full of money, and I'm going to be standing beside him." Yet when English does indeed make a fortune, when the travel website Kayak is sold for almost two billion dollars--the first thing he thinks about is how to give the money away: "What else would you do with it?" The second thing he thinks is, What's next? With the power of a consummate storyteller, Tracy Kidder casts a fresh, critical, and often humorous eye on the way new ideas and new money are reshaping our culture and the world.

Trump and the Media

by Zizi Papacharissi Pablo Boczkowski

The election of Donald Trump and the great disruption in the news and social media. Donald Trump's election as the 45th President of the United States came as something of a surprise—to many analysts, journalists, and voters. The New York Times's The Upshot gave Hillary Clinton an 85 percent chance of winning the White House even as the returns began to come in. What happened? And what role did the news and social media play in the election? In Trump and the Media, journalism and technology experts grapple with these questions in a series of short, thought-provoking essays. Considering the disruption of the media landscape, the disconnect between many voters and the established news outlets, the emergence of fake news and “alternative facts,” and Trump's own use of social media, these essays provide a window onto broader transformations in the relationship between information and politics in the twenty-first century. The contributors find historical roots to current events in Cold War notions of "us" versus "them," trace the genealogy of the assault on facts, and chart the collapse of traditional news gatekeepers. They consider such topics as Trump's tweets (diagnosed by one writer as “Twitterosis”) and the constant media exposure given to Trump during the campaign. They propose photojournalists as visual fact checkers (“lessons of the paparazzi”) and debate whether Trump's administration is authoritarian or just authoritarian-like. Finally, they consider future strategies for the news and social media to improve the quality of democratic life. Contributors Mike Ananny, Chris W. Anderson, Rodney Benson, Pablo J.

The Trump Presidency, Journalism, and Democracy (Routledge Research in Journalism)

by Robert E. Gutsche Jr.

This book examines the disruptive nature of Trump news – both the news his administration makes and the coverage of it – related to dominant paradigms and ideologies of U.S. journalism. By relying on conceptualizations of media memory and "othering" through news coverage that enhances socio-conservative positions on issues such as immigration, the book positions this moment in a time of contestation. Contributors ranging from scholars, professionals, and media critics operate in unison to analyze today’s interconnected challenges to traditional practices within media spheres posed by Trump news. The outcomes should resonate with citizens who rely on journalism for civic engagement and who are active in social change
