The document discusses the future of advertising and focuses on three main areas: behavioral design, game design, and lean startup principles. It argues that agencies need to master influencing consumer behavior through small, persuasive design details rather than big ideas or creativity alone.

Behavioral economics and persuasion techniques will be increasingly important to consider. Disruptive startups often solve consumer problems more elegantly through better design of triggers and barriers.
