Layer 01 · The Evolution

From the mill floor
to the machine mind.

Ten chapters across roughly 130 years. Move from left to right through the eras marketers name and debate, from Keith's contested story to Kotler's Marketing 5.0. Every milestone links to its source.

Framework reference: PR Smith’s SOSTAC® Planning Methodology.

01 / 10
1890s –1900sPrehistory

Before the Discipline

Selling is ancient. In 1898, adman E. St. Elmo Lewis began articulating attention, interest and desire as a teachable sequence. Action completed the now-familiar AIDA model later.

REMEMBER THISEvery funnel you have drawn descends from an idea Lewis began articulating in 1898.
View 2 sourced milestones
1898

Elias St. Elmo Lewis begins articulating attention, interest and desire; action is added later to form the familiar AIDA sequence. [1]

1900s

Advertising trade press and the first agencies professionalize copywriting; 'scientific advertising' becomes an ambition. [2]

1900s –1920sMarketing 1.0 · product-centric

The Production Era

Factories were the heroes. The belief was simple: make a good product cheap enough and it sells itself. Marketing barely had a desk. (Historians dispute how neat these 'eras' really were; we flag that below.)

REMEMBER THISProduction era: 'a good product sells itself.'
View 2 sourced milestones
1960

Robert J. Keith names the eras retrospectively in 'The Marketing Revolution' (Journal of Marketing), describing Pillsbury's evolution from production-oriented firm onward. [1]

Contested: scholars such as Fullerton have challenged the eras narrative as too tidy, aggressive selling and demand creation existed throughout the industrial age. [2]

1920s –1950sMarketing 1.0 → 2.0

The Selling Era

Then factories made more than people wanted. Radio walked ads into living rooms, salesmen walked door to door, and the hard sell became a profession.

REMEMBER THISSelling era: 'we must sell what we make.'
View 2 sourced milestones
1920s–40s

In Keith's Pillsbury account, the company becomes sales-oriented: 'we must sell what we make', dealers, merchandising, and advertising move to the center. [1]

Mid-20th c.

BANT (Budget, Authority, Need, Timeline) is commonly associated with IBM enterprise selling. Practitioner histories often cite the 1950s, but a definitive public original manual or inventor is not established. [2]

1950s –1960sMarketing 1.0 codified

The Marketing Concept

The big bang. In one decade marketing got its vocabulary: segmentation (1956), the 4Ps (1960), 'Marketing Myopia' (1960), Kotler's textbook (1967). The radical new rule: start with the customer, not the factory.

REMEMBER THISThe 1960s named everything, and put the customer first.
View 5 sourced milestones
1956

Wendell Smith distinguishes product differentiation from market segmentation in the Journal of Marketing, the seed of STP. [1]

E. Jerome McCarthy compresses Borden's twelve-ingredient 'marketing mix' into the 4Ps in Basic Marketing. [2]

1960

Theodore Levitt's 'Marketing Myopia' (HBR) tells railroads they were in the transportation business all along. [3]

1960

1967

Philip Kotler publishes Marketing Management, the field's defining textbook, now in its 16th edition. [5]

1970s –1980sMarketing 2.0 · consumer-oriented

The Battle for the Mind

Too many ads, too little mind. Ries and Trout said the real fight is not on the shelf, it is inside the buyer's head: own one word, one rung, one position.

REMEMBER THISPositioning: win a slot in memory, not just space on shelves.
View 5 sourced milestones
1972

Ries & Trout publish 'The Positioning Era Cometh' in Advertising Age; the 1981 book sells millions. [1]

1984

Cialdini's Influence distills persuasion into teachable principles, reciprocity to scarcity. [5]

1983 –1990sToward Marketing 3.0

The Relationship Turn

The sale stopped being the finish line. Berry named relationship marketing in 1983, brands became measurable assets, and keeping a customer became strategy, not courtesy.

REMEMBER THISThe sale is the start of the relationship, not the end of it.
View 5 sourced milestones
1983

Leonard Berry coins 'relationship marketing' at the AMA services conference: attract, maintain, enhance. [1]

The Digital Disruption

2004 –2015Marketing 3.0 · human-centric (2010)

2015 –2021Marketing 4.0 · traditional→digital (2016)

Data, Platforms & the Privacy Reckoning

Epilogue · Why This Matters Now

The tools are brand new.
The questions are a century old.

Every prompt is a brief. Every AI output you approve is a positioning, pricing or persuasion decision. Faster execution makes judgment more valuable, and these ideas give that judgment a foundation.
