David Ogilvy (1911–1999) was a British-American advertising executive who founded Ogilvy & Mather and built research-based creative advertising into a discipline. His work bridged direct-response advertising (measurable, tested) and brand advertising (emotional, memorable), insisting that both should be grounded in research about the consumer.

Core ideas

  • Research before writing: Ogilvy argued that effective advertising begins with understanding the consumer, not with creative inspiration. He spent weeks studying a product and its audience before writing a word of copy. “Advertising people who ignore research are as dangerous as generals who ignore decodes of enemy signals” [@ogilvy1983].
  • The headline as investment: Ogilvy’s often-cited claim that five times as many people read the headline as the body copy made the headline the most important sentence in advertising. His own headlines exemplified the principle — specific, benefit-driven, and long when length served clarity.
  • The big idea: Ogilvy believed that every effective campaign was built on one central idea — a proposition so compelling that it could sustain years of advertising. “Unless your advertising contains a big idea, it will pass like a ship in the night” [@ogilvy1983].
