A toxic army of trolls goes after women in the gaming industry, giving birth to an online movement of disaffected men. This "manosphere" contributes to the resurgence of Donald Trump and a constitutional crisis that holds American democracy in the balance.

After the twin disasters of the massacre in Myanmar and the 2016 election, social media undergoes a reckoning in the halls of Congress… until a novel virus uncorks a global pandemic and a contagion of hoaxes, conspiracies, and lies online.

North Korea hacks a movie studio over a screwball comedy, inspiring America’s enemies to launch cyberattacks against the U.S. To roil an election, one even unleashes a network of trolls pitting ordinary Americans against each other, online and in the streets.

When was the last time you felt good about the internet? Today’s online landscape is a harrowing one. People screaming at each other on social media. Violent videos going viral.

In LONG SHADOW: BREAKING THE INTERNET, Pulitzer-finalist historian, author, and journalist Garrett Graff retraces 30 years of web history — a tangle of GIFs, blogs, apps, and hashtags — to answer the bewildering question many ask when they go online today: “How did we get here?”

It’s the story of mankind’s greatest invention, but it's also about the biggest crisis facing society today: how the web's unlimited feed of data morphed into a firehose of hoaxes, conspiracy theories, and lies that divided Americans over things we once agreed on, like science, diversity, and even democracy itself.
