The history of marketing began as merchants shouting their wares in ancient marketplaces. The printing press enabled the first advertisements, while radio and television transformed selling into mass persuasion. The digital revolution brought targeted campaigns that track consumer behavior with surgical precision. Today's marketers wield data like a scalpel, dissecting audience preferences to craft messages that feel personal yet reach millions. What started as simple announcements has evolved into a complex science of human psychology, technology, and commerce.
