Science has permeated marketing for decades. Fans of the television drama Mad Men saw a fictionalized encounter when an IBM System/360 mainframe computer physically displaced the creative department of a late-1960s advertising agency. In reality, though, the 1960s through the early 1990s witnessed a happy marriage of advertising and technology as marketers mastered both the medium of television and the science of Nielsen ratings. These years gave birth to iconic advertising messages in categories ranging from sparkling beverages (“I’d like to buy the world a Coke”) to credit cards (“American Express. Don’t leave home without it”) to air travel (“British Airways: the world’s favourite airline”).
