Segmentation was invented because a marketer could not know an individual. Groups were the best available approximation: divide a market by what can be observed, describe each division with a persona, and address the description rather than the person. That compromise has held for sixty years, and the reason for it is quietly disappearing.
Elliott King put the change in front of a room of university leaders at BETT in two thousand and seventeen, by asking them to picture a teenager from only a decade earlier.
Media used to arrive in places, at times somebody else chose
"Let's talk about the seventeen year old from just ten years ago. The iPhone one had only just been invented, so let's talk about the pre-smartphone age. The average seventeen year old would have been waking up in his or her bedroom, running down to have breakfast, probably watching TV, possibly reading the back of the cereal pack, reading a free newspaper on the way, listening to the radio in the car."
Watch this moment, 25:53
Every encounter in that list happened somewhere specific, at a time chosen by a broadcaster or a publisher. Television at breakfast, a cereal packet, a free newspaper, the radio in the car. Media planning worked because the places were few, the times were known, and a demographic was a reasonable proxy for who would be there.
That structure is what Chapter 1, A Brief History of Marketing, describes as the one-way broadcast era, and it explains why the four P's held for as long as they did. When a marketer controls place and promotion, a product-centred model is workable.
Personas are a description of a person, not of a moment
Chapter 3, Strategic Marketing Planning, asks for personas built from demographic and psychographic factors, and for an understanding of the path a customer takes from awareness to purchase. Both remain necessary. Both describe a stable person rather than a particular moment, and the gap between those two things has widened considerably.
A persona says who somebody is. It does not say that they are standing in an unfamiliar city with forty minutes before a meeting, having already rejected two options. Those facts change the correct answer entirely, and until recently no marketing system could hold them.
The four C's anticipated the direction. Lauterborn's replacement of product, price, place and promotion with customer, cost, convenience and communication moved the model towards the individual. Convenience, in particular, is a claim about circumstances rather than about distribution.
Context is the segment of one, and it is nearly available
A device that knows location, calendar, recent activity and, increasingly, tone of voice holds most of what a segmentation exercise was approximating. The question stops being which group a person belongs to and becomes what is true about this person now.
This is the part that is not solved. An assistant answers the question it is asked and has little standing picture of the situation around it, so the person supplies that picture by hand at every exchange. The failure is not comprehension or reasoning: supply the circumstances explicitly and the same system answers well immediately.
For marketing the implication is specific. Content built to satisfy a persona will be retrieved for the subject and passed over for the situation, because a system assembling an answer to a situational question needs material that addresses circumstances, constraints and trade-offs rather than categories.
The unlock is documented meaning, not a larger model
What a person means is the hardest thing in this chain to establish, and it is the thing everything else depends on. Untangling an intention, confirming it rather than assuming it, and recording it so it persists is an editorial discipline rather than a technical one.
Organisations have been doing a version of this for years without calling it that. A well-run customer research programme untangles meaning. A specific, attributed, situational piece of expertise documents it. Chapter 4, Digital Marketing Tools and Tactics, argues for episodic expert content on engagement grounds, and it turns out to be the same material a retrieval system needs to answer a situational question well.
The practical test is whether published material would help somebody decide in a particular circumstance, or merely inform them about a category. The second is a brochure. The first is usable by a person and by a machine acting for one.
What this changes in a marketing plan
Segmentation and targeting remain, because a business must still choose whom to serve. What changes is what gets published against those choices: material organised around the situations in which the product is chosen, rather than around the attributes of the people who choose it.
That is a modest-sounding amendment with a substantial consequence for a content calendar, and it is consistent with the integrated approach Chapter 9, Managing an Integrated Strategy, sets out: a fixed strategic objective, with the tactical layer free to follow the evidence.
Elliott King, co-author of this book and an AI visibility expert, develops the argument about context and meaning in his own account of this seminar. The book carries the planning and persona frameworks, and his work at FINN Partners applies them.
Frequently asked questions
Are customer personas still useful?
Yes, for deciding whom to serve and how to position. What they cannot do is describe the moment in which a decision is made, and situational detail is what a machine assembling an answer needs. Personas are necessary and no longer sufficient.
What is contextual marketing?
Addressing the circumstances a person is in rather than the group they belong to: location, constraint, stage and intent. Segmentation approximated this by grouping people whose circumstances were likely to be similar. Devices and assistants increasingly hold the circumstances directly, which narrows the approximation towards the individual.
Why does content need to be situational rather than general?
Because the questions people now ask carry their circumstances inside them, and a system answering those questions draws on material that addresses circumstances. General category content is retrieved for the subject and ignored for the situation, which is where the decision is actually made.
