In 2017, Bob Hoffman wrote BadMen: How Advertising Went from a Minor Annoyance to a Major Menace. It was selected as Best Of Marketing, 2017. Five years later Bob revisits advertising's tracking-based online advertising industry and finds it far more corrupt and dangerous than ever. In ADSCAM: How Online Advertising Gave Birth to One of History's Greatest Frauds, and Became a Threat to Democracy, Bob concludes that the tracking-based online advertising industry is "a criminal racket of epic proportions. It is a giant worldwide scam -- organized crime at a global scale that has been normalized by involving virtually every major corporation, every pretty-sounding trade organization, and the entire advertising, marketing, and digital media industry."
