AN INSTANT NEW YORK TIMES BESTSELLER!! Named a Best Book of 2019 by TIME, Amazon, and The Washington Post A Wired Must-Read Book of Summer “Gretchen McCulloch is the internet’s favorite linguist, and this book is essential reading. Reading her work is like suddenly being able to see the matrix.” —Jonny Sun, author of everyone's a aliebn when ur a aliebn too Because Internet is for anyone who's ever puzzled over how to punctuate a text message or wondered where memes come from. It's the perfect book for understanding how the internet is changing the English language, why that's a good thing, and what our online interactions reveal about who we are. Language is humanity's most spectacular open-source project, and the internet is making our language change faster and in more interesting ways than ever before. Internet conversations are structured by the shape of our apps and platforms, from the grammar of status updates to the protocols of comments and @replies. Linguistically inventive online communities spread new slang and jargon with dizzying speed. What's more, social media is a vast laboratory of unedited, unfiltered words where we can watch language evolve in real time. Even the most absurd-looking slang has genuine patterns behind it. Internet linguist Gretchen McCulloch explores the deep forces that shape human language and influence the way we communicate with one another. She explains how your first social internet experience influences whether you prefer "LOL" or "lol," why ~sparkly tildes~ succeeded where centuries of proposals for irony punctuation had failed, what emoji have in common with physical gestures, and how the artfully disarrayed language of animal memes like lolcats and doggo made them more likely to spread.

Castells helps us understand how the Internet came into being and how it is affecting every area of human life. This guide reveals the Internet's huge capacity to liberate, but also its possibility to exclude those who do not have access to it.

Janet Abbate recounts the key players and technologies that allowed the Internet to develop; but her main focus is always on the social and cultural factors that influenced the Internet's design and use. Since the late 1960s the Internet has grown from a single experimental network serving a dozen sites in the United States to a network of networks linking millions of computers worldwide. In Inventing the Internet, Janet Abbate recounts the key players and technologies that allowed the Internet to develop; but her main focus is always on the social and cultural factors that influenced the Internets design and use. The story she unfolds is an often twisting tale of collaboration and conflict among a remarkable variety of players, including government and military agencies, computer scientists in academia and industry, graduate students, telecommunications companies, standards organizations, and network users. The story starts with the early networking breakthroughs formulated in Cold War think tanks and realized in the Defense Department's creation of the ARPANET. It ends with the emergence of the Internet and its rapid and seemingly chaotic growth. Abbate looks at how academic and military influences and attitudes shaped both networks; how the usual lines between producer and user of a technology were crossed with interesting and unique results; and how later users invented their own very successful applications, such as electronic mail and the World Wide Web. She concludes that such applications continue the trend of decentralized, user-driven development that has characterized the Internet's entire history and that the key to the Internet's success has been a commitment to flexibility and diversity, both in technical design and in organizational culture.

As seen on CBS 60 Minutes "No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider." Did you know that these twenty-six words are responsible for much of America's multibillion-dollar online industry? What we can and cannot write, say, and do online is based on just one law—a law that protects online services from lawsuits based on user content. Jeff Kosseff exposes the workings of Section 230 of the Communications Decency Act, which has lived mostly in the shadows since its enshrinement in 1996. Because many segments of American society now exist largely online, Kosseff argues that we need to understand and pay attention to what Section 230 really means and how it affects what we like, share, and comment upon every day. The Twenty-Six Words That Created the Internet tells the story of the institutions that flourished as a result of this powerful statute. It introduces us to those who created the law, those who advocated for it, and those involved in some of the most prominent cases decided under the law. Kosseff assesses the law that has facilitated freedom of online speech, trolling, and much more. His keen eye for the law, combined with his background as an award-winning journalist, demystifies a statute that affects all our lives –for good and for ill. While Section 230 may be imperfect and in need of refinement, Kosseff maintains that it is necessary to foster free speech and innovation.
