About the Author

Some books are written by academics. Some are written by executives. Some are written by people who spent decades in a single industry mastering one corner of a very large subject.

This book was written by someone who simply could not stop paying attention.

Jack Klinger spent seven years working in the entertainment industry in the 1970s — in nightclubs, on stage, and in theaters. He watched performers hold rooms. He watched audiences move from skepticism to belief in the space of a single song. He had conversations with entertainers, managers, and technicians that most people never get to have — real conversations, backstage and after hours, about what actually works when you are standing in front of a crowd and trying to make them feel something.

When he left that world he took everything he had learned about performance, persuasion, and human attention and applied it to building a company. For over thirty seven years he ran a business focused on the sales, marketing, and manufacturing of custom products for the entertainment industry.

Through all of it one thread ran consistently underneath everything. A fascination with influence. With how it works. Where it comes from. Why certain voices move people and others don't. How the invisible forces that shaped a crowd in a nightclub in 1974 are the same forces shaping a TikTok feed today — just running faster, on different hardware, at a scale nobody in that nightclub could have imagined.

Now retired, Jack spent more than a year researching and writing THE INFLUENCERS — reading deeply into the history of influence, the psychology behind it, the evolution of media from the magic lantern shows of the 1800s through the algorithm driven feeds of today, and the rapidly changing landscape of AI tools reshaping what it means to be a creator.

The result is the book you are holding now. Built on forty five years of living inside the subject.
