Marketing as a discipline has changed dramatically over the centuries. What began as simple trade between individuals has evolved into a sophisticated, relationship-driven profession. Looking at how marketing has developed through distinct eras helps explain why modern marketing works the way it does, and where its core principles came from.
The Simple Trade Era
From the beginning of trade through to the mid-19th century, commerce was defined by simple exchange. Everything was handmade or harvested, which meant supply was naturally limited, and commodities ruled the marketplace. The earliest forms of advertising began to emerge during this period. The first magazines appeared in the 1730s, and the first paid newspaper advertisement is recorded in 1836. By 1839, advertising had grown prominent enough that posters on private property were banned in London.
The Production Era
Lasting around sixty years, from the 1860s to the 1920s, the Production Era began around the time of the Industrial Revolution. The prevailing business philosophy was captured by the phrase "build it and they will come": demand was high and supply was the constraint, so businesses focused on producing as much as possible. This period saw the rise of mass production, the earliest recorded billboard rental in 1867, and even the earliest recorded use of the telegraph for mass unsolicited messaging in 1864 — an early ancestor of what would later be called spam.
The Sales Era
Between the 1920s and 1940s, competition for market share increased significantly. As more businesses produced similar goods, companies had to work harder to sell their products, and new sales techniques emerged as a result. This era coincided with the rise of radio as an advertising medium; radio advertising began in 1922, and by 1933 the number of US homes with a radio had passed 50 per cent, giving advertisers a powerful new channel to reach audiences.
The Marketing Department Era
From the 1940s to the 1960s, businesses began to bring sales, advertising, promotion and public relations together into a single marketing department, recognising that these functions worked best when coordinated. This era also saw the arrival of major new communication channels. The first recorded use of television advertising came in 1941, and by 1946 more than half of households had a telephone, opening further routes to reach customers directly.
The Marketing Company Era
From the 1960s onward, marketing moved to the centre of business thinking. Dedicated marketing companies began to emerge once the value of marketing had been firmly established, and a more customer-focused approach took hold. Telemarketing emerged as a common tactic, and the 1960s saw the start of humorous, ironic and irreverent advertising styles that remain influential today.
Advances in technology from the 1970s onward continually opened up new forms of marketing. The first mobile phone call was made in 1973, the IBM personal computer was introduced in 1981, and the Apple Macintosh launched in 1984 — each development gradually reshaping how businesses could reach and communicate with their audiences.
The Relationship Marketing Era
From the 1990s to the present day, the central goal of marketing has shifted towards building long-term relationships with customers rather than focusing solely on individual transactions. The method behind this approach rests on delivering value for customers, being responsive to their needs, and building trust over time. The continued advancement of technology has led to a significant rise in online marketing, giving organisations more channels than ever to develop and maintain these relationships across websites, mobile devices and digital platforms.
Understanding this progression matters because each era left its mark on modern practice. The production mindset, the sales techniques, the coordinated marketing department and the relationship focus all coexist in contemporary marketing, and a strong marketer draws on all of them.
