# Brave New Hive > A marketing pedia for brands in the age of AI. The Hive is where the knowledge is kept. brave-new.com is where it gets used. Published by Brave New. Every entry is dated, sourced and signed by Anne Becheru. ## Principles - [The 4 Ps of marketing](https://bravenewhive.com/principles/4-ps-of-marketing/): The marketing mix says a marketer's job is to set four controllable variables: product, price, place and promotion. It is a classification, not a theory, and has never been tested as one. - [Positioning in marketing](https://bravenewhive.com/principles/positioning-in-marketing/): Positioning, as Ries and Trout set it out in 1972, claims that a brand wins by occupying one clear slot in the prospect's memory. The memory half holds up. - [Market segmentation](https://bravenewhive.com/principles/market-segmentation/): Market segmentation claims a market is not one demand curve but several, and that a firm does better serving some of them well than all of them adequately. The evidence supports that claim for categories: buyers differ in what they want and how much they use. - [Unique selling proposition (USP)](https://bravenewhive.com/principles/unique-selling-proposition/): Rosser Reeves set out the unique selling proposition in 1961 as a three-part rule: every advertisement must offer a specific benefit, competitors must not claim it, and it must be strong enough to pull new buyers. His evidence was agency data. - [Mental availability and physical availability](https://bravenewhive.com/principles/mental-and-physical-availability/): Sharp's claim is that brands grow by being easy to think of and easy to buy, because loyalty follows market share rather than causing it. The second half is well tested: double jeopardy holds in 32 differentiated replications, in cars, business banking, aircraft and packaged goods. - [The Long and the Short of It](https://bravenewhive.com/principles/the-long-and-the-short-of-it/): Binet and Field claim that advertising works in two modes on two clocks: activation sells now and fades, brand building sells later and compounds, so budgets should lean long, at roughly 60:40. The evidence is 996 award entries in which volume arrives within months, pricing power takes years, and efficiency peaks at 30 to 50 percent activation. - [AIDA](https://bravenewhive.com/principles/aida/): AIDA claims that a buyer passes through attention, interest, desire and action in that order, and that a message should push them along it. The attribution to E. St. Elmo Lewis in 1898 rests on one uncited sentence in a 1925 textbook; the four steps first appear in salesmanship magazines of 1903 and 1904 under other names. - [Brand equity](https://bravenewhive.com/principles/brand-equity/): Brand equity is the claim that a name adds value beyond what the product does, and that this value can be built, measured and banked. Aaker (1991) listed the assets; Keller (1993) located them in the customer's memory. ## History of advertising - [1841. Who invented the advertising agency](https://bravenewhive.com/history-of-advertising/1841-who-invented-the-advertising-agency/): Volney Palmer opened the first US ad agency in 1841, paid by the newspapers. How that commission shaped agencies to the Mad Men era, and what replaced it. - [1922. The first paid radio commercial](https://bravenewhive.com/history-of-advertising/1922-the-first-radio-commercial/): On 28 August 1922 a property firm paid WEAF $50 to talk about apartments. What radio's first thirty years say about sponsoring a show versus buying the spot. - [1941. The first television commercial](https://bravenewhive.com/history-of-advertising/1941-the-first-television-commercial/): The $9 Bulova spot of 1 July 1941 created the paid TV unit. Why it took thirty years, a scandal and a tobacco ban to become the 30-second spot you buy today. - [1960. The 4 Ps of marketing are published](https://bravenewhive.com/history-of-advertising/1960-the-four-ps/): 1960: McCarthy's four Ps and Levitt's Marketing Myopia turned marketing into a taught discipline, and left the agency holding one box out of four. - [1972. The Positioning Era Cometh](https://bravenewhive.com/history-of-advertising/1972-the-positioning-era/): In April 1972 Ries and Trout told Advertising Age the battleground had moved to the prospect's mind. What Avis, Volkswagen and 7-Up had proved, and what to do now. - [1994. The first banner ad](https://bravenewhive.com/history-of-advertising/1994-the-first-banner-ad/): HotWired ran the first banners on 27 October 1994. What the 44 per cent click rate and the fall to 0.1 per cent mean for your display budget. - [2000. Google launches AdWords](https://bravenewhive.com/history-of-advertising/2000-google-adwords/): In October 2000 Google let any business buy a search query. The AdWords record, the auction, the commission it bypassed, and what to do with it. - [2022. ChatGPT is released](https://bravenewhive.com/history-of-advertising/2022-chatgpt/): ChatGPT, 30 November 2022: the day the answer replaced the results page. What the record shows, what it changed for brands, and what to do on Monday. ## Branding - [Double Jeopardy: small brands lose twice](https://bravenewhive.com/branding/double-jeopardy/): Small brands have fewer buyers, and those buyers are slightly less loyal to them. That is the whole of Double Jeopardy, and it is one of the few patterns in marketing that holds across categories, countries and decades. - [Kapferer's brand identity prism: six facets and no measurement](https://bravenewhive.com/branding/kapferer-brand-identity-prism/): Jean-Noel Kapferer's prism, first published in French in 1991 and in English in 1992, describes a brand's identity in six facets: physique, personality, culture, relationship, reflection and self-image. It is the most used identity framework in European brand practice and it has almost no empirical validation. - [Marketing myopia: the question Levitt asked and the answer that went wrong](https://bravenewhive.com/branding/marketing-myopia/): Theodore Levitt's 1960 essay argued that industries decline because they define themselves by what they make rather than by what the customer needs. The railroads were in the railroad business, not the transportation business, and the cars and planes took the customers. - [Mere exposure: familiarity is pleasant, and that is a problem](https://bravenewhive.com/branding/mere-exposure/): Robert Zajonc showed in 1968 that repeated exposure to something increases liking for it, with no argument, no information and no awareness that it is happening. It is among the most replicated findings in social psychology, confirmed across hundreds of experiments. - [The 95-5 rule: most of your buyers are not buying](https://bravenewhive.com/branding/the-95-5-rule/): At any given moment, around 95 per cent of the businesses you want as customers are not in the market for what you sell, and about 5 per cent are. The figure comes from the Ehrenberg-Bass Institute's work for the LinkedIn B2B Institute in 2021 and it is a derived heuristic, not a survey result. - [The branding canon: what to read, in which order, and what it argues about](https://bravenewhive.com/branding/the-branding-canon/): Branding has a literature of perhaps fifteen works that everything else cites, and they do not agree with each other. One tradition, from Ries and Trout through Aaker and Keller, holds that a brand is a position in the mind, won by meaningful difference. - [Aaker or Keller: which brand equity model answers which question](https://bravenewhive.com/branding/aaker-or-keller/): Two models define brand equity and they are not alternatives. Aaker (1991) counts what the brand is worth to the firm, as assets and liabilities. - [Distinctive brand assets: distinctive, not different](https://bravenewhive.com/branding/distinctive-brand-assets/): Differentiation says give buyers a reason to choose you. Distinctiveness says make sure they can find you at all. - [Excess share of voice: the exchange rate between voice and share](https://bravenewhive.com/branding/excess-share-of-voice/): Excess share of voice is your share of the category's advertising presence minus your share of its revenue. The relationship between the two was set out by John Philip Jones in Harvard Business Review in 1990 and turned into a planning rule by Binet and Field using the IPA Effectiveness Databank. - [The Coke and Pepsi brain study: what McClure found in 2004, and what the result can and cannot carry](https://bravenewhive.com/branding/the-coke-pepsi-study/): In 2004 Samuel McClure and colleagues at Baylor College of Medicine scanned people drinking Coke and Pepsi. Blind, preferences were split and brain activity in a reward region tracked the taste. - [System 1 and System 2 thinking in marketing: what the two-system model says, and what marketers added to it](https://bravenewhive.com/branding/system-1-and-system-2/): System 1 and System 2 are the names Daniel Kahneman used in Thinking, Fast and Slow for two modes of thought: fast, automatic and effortless on one side, slow, deliberate and effortful on the other. The labels came from Stanovich and West in 2000. - [The somatic marker hypothesis: emotion as the machinery of choosing, and the experiment that was challenged](https://bravenewhive.com/branding/somatic-markers/): Antonio Damasio argued in 1994 that emotion is part of how people decide, not interference with it. Patients with damage to a specific region of the prefrontal cortex kept their reasoning and lost their ability to choose well. - [Processing fluency in marketing: what is easy to read feels true](https://bravenewhive.com/branding/processing-fluency-in-marketing/): Things that are easy to perceive, read, say and remember are judged more true, more likeable and more familiar than the same things made harder. Reber, Schwarz and Winkielman set the mechanism out in 2004: the brain registers the ease of its own processing and misreads that ease as a property of the thing processed. - [Loss aversion in marketing: the asymmetry that sells urgency, and the fight over whether it exists](https://bravenewhive.com/branding/loss-aversion-in-marketing/): Kahneman and Tversky's prospect theory, published in 1979, holds that losses weigh more heavily than gains of the same size. The usual figure is about twice as heavily, from their 1992 estimate. ## AI marketing - [What is AI marketing?](https://bravenewhive.com/ai-marketing/what-is-ai-marketing/): AI marketing is the use of artificial intelligence systems inside marketing work: to research buyers, generate and test creative, target and bid on media, and to earn a place in the answers AI assistants give when somebody asks for a recommendation. It is a set of tools and a new distribution channel at the same time, and most teams are only treating it as the first. - [What is generative engine optimization (GEO)?](https://bravenewhive.com/ai-marketing/what-is-generative-engine-optimization/): Generative engine optimization, or GEO, is the practice of writing and structuring content so that generative engines cite it in the answers they produce. The term comes from a 2023 research paper by Pranjal Aggarwal and colleagues at Princeton, the Georgia Institute of Technology, the Allen Institute for AI and IIT Delhi. - [What is answer engine optimization (AEO)?](https://bravenewhive.com/ai-marketing/what-is-answer-engine-optimization/): Answer engine optimization, or AEO, is the practice of preparing content so that it is used in a direct answer rather than in a list of links. In practice it means answering one question per page, plainly and early, in a block that can be lifted out whole and still make sense. - [What is AI SEO?](https://bravenewhive.com/ai-marketing/what-is-ai-seo/): AI SEO is the work of getting a company named, described correctly and cited in the answers that AI assistants and AI search features produce. It shares a base with search engine optimisation, a page a machine can reach and read, and adds the part that decides an answer: a plain definition, one description of the company repeated everywhere it appears, and claims an engine can attribute to a source. - [What is a retrievable brand?](https://bravenewhive.com/ai-marketing/what-is-a-retrievable-brand/): A retrievable brand is one an AI system can find, identify correctly and describe accurately when somebody asks about its category. Three conditions, and all three have to hold: the system has encountered you, it knows which entity you are, and what it says about you is true. - [How do AI models choose which brands to recommend?](https://bravenewhive.com/ai-marketing/how-ai-models-choose-brands/): Two different mechanisms, and which one is running decides what you can do about it. Either the model answers from what it absorbed during training, or it searches the live web first and builds an answer from what it finds. The first is slow to influence and the second is fast, and most advice in circulation assumes the second without checking. - [How do I get my company mentioned in ChatGPT and Perplexity answers?](https://bravenewhive.com/ai-marketing/get-mentioned-in-chatgpt-and-perplexity/): By being described, accurately and repeatedly, in sources the engines use, and by making sure the engine knows which company you are. There is no submission form, no paid placement in the answer itself, and no technical switch. Anyone offering guaranteed inclusion is describing something that does not exist. - [What is llms.txt?](https://bravenewhive.com/ai-marketing/what-is-llms-txt/): A proposed standard: a plain markdown file at the root of a website, /llms.txt, giving language models a curated guide to what the site contains and which pages matter. It was proposed by Jeremy Howard of Answer.AI in September 2024. It is a proposal, not a ratified standard, and adoption by the major AI companies is limited. - [Why does brand consistency matter for AI search?](https://bravenewhive.com/ai-marketing/why-brand-consistency-matters-for-ai-search/): Because an AI system builds its account of your company by aggregating everything it has seen about you, and inconsistency does not average out into a blurry picture. It produces either a confident wrong answer or a merged entity that is partly you and partly somebody else. ## Reputation - [Brand versus reputation: what is the difference?](https://bravenewhive.com/reputation/brand-versus-reputation/): A brand is what a company says and shows about itself. A reputation is what other people conclude from what it does. One is authored, the other is earned, and in a buying meeting the second one decides. - [The Edelman Trust Barometer](https://bravenewhive.com/reputation/the-edelman-trust-barometer/): An annual survey of trust in four institutions, business, government, media and non-governmental organisations, published by the communications firm Edelman every year since 2001. It is the most widely cited public measure of institutional trust, and it is worth understanding both what it shows and what it is. - [1982. The Tylenol case](https://bravenewhive.com/reputation/the-tylenol-case-1982/): In the autumn of 1982, seven people in the Chicago area died after taking Extra-Strength Tylenol capsules that had been laced with potassium cyanide. Johnson & Johnson pulled the product nationally, warned the public not to take it, and reintroduced it in tamper-evident packaging. It remains the reference case in crisis communications, and it is routinely misread. - [Trust architecture](https://bravenewhive.com/reputation/trust-architecture/): Trust architecture is Brave New's name for the deliberate arrangement of evidence a buyer encounters before they are willing to commit. It is our term, not an established concept in the literature, and this entry says so plainly because a reference work that passes off its own vocabulary as received wisdom is not a reference work. - [Reputation risk](https://bravenewhive.com/reputation/reputation-risk/): Reputation risk is the exposure a company carries from the gap between what people expect of it and what it actually does. It is not the risk of bad publicity. It is the risk that an existing gap gets discovered, which is a different thing and is managed differently. ## Readings - [How Brands Grow. Byron Sharp (2010)](https://bravenewhive.com/readings/how-brands-grow-byron-sharp/): The evidence-based case that brands grow by reaching more buyers rather than by deepening loyalty among the ones they have. Built on decades of purchase panel data from the Ehrenberg-Bass Institute, and the most disruptive marketing book of the last twenty years. - [Ogilvy on Advertising. David Ogilvy (1983)](https://bravenewhive.com/readings/ogilvy-on-advertising/): The working manual of the man who built Ogilvy & Mather, on headlines, layouts, research, and the difference between advertising that wins awards and advertising that sells. It is a book of craft instructions, not a theory, and it should be read as one. - [Positioning: The Battle for Your Mind. Al Ries and Jack Trout (1981)](https://bravenewhive.com/readings/positioning-ries-and-trout/): The book that moved the battleground from the product to the prospect's mind. Own a word, or own a place relative to the leader, before somebody else does. It began as a series of articles in Advertising Age in 1972 and has shaped how marketers talk ever since. - [Thinking, Fast and Slow. Daniel Kahneman (2011)](https://bravenewhive.com/readings/thinking-fast-and-slow-kahneman/): Kahneman's summary of a career's work on judgement and how people decide, built around two modes of thought: a fast automatic one that runs most of the time, and a slow deliberate one that mostly arrives afterwards to justify what the first already decided. - [The Long and the Short of It. Les Binet and Peter Field (2013)](https://bravenewhive.com/readings/the-long-and-the-short-of-it-binet-field/): The IPA study that separated brand building from sales activation, showed they work on different timescales through different mechanisms, and put a number on the split between them. The most quoted finding in modern marketing effectiveness, and the most misquoted. - [Alchemy. Rory Sutherland (2019)](https://bravenewhive.com/readings/alchemy-rory-sutherland/): An argument for the value of ideas that do not make logical sense but work anyway. Sutherland, vice chairman of Ogilvy UK, makes the case that the search for rational, measurable, defensible marketing has squeezed out the irrational solutions that often deliver the largest returns. - [Influence. Robert Cialdini (1984)](https://bravenewhive.com/readings/influence-cialdini/): The book that catalogued the mechanisms of persuasion into six principles, built on three years of fieldwork inside sales training, fundraising and advertising operations. It is the most useful book on this list and the most misused. ## Research - [How AI engines answer marketing questions: a citation study](https://bravenewhive.com/research/how-ai-engines-answer-marketing-questions/): We asked a live AI engine eight marketing questions and checked every source it named. It performed a live search for two of them. Of the sources it listed for the rest, 21 did not exist. This is our own test, run on one engine on one day, and the method and its limits are below. - [How the AI search vocabulary moved in a year](https://bravenewhive.com/research/how-the-ai-search-vocabulary-moved/): Three terms compete to name the same worry: that buyers are asking an AI assistant instead of a search engine. We tracked all three in US search volume across a year. AI SEO is the largest, generative engine optimization peaked early and fell back, and answer engine optimization climbed from almost nothing to a real number. Our own data, fetched 14 September 2026. - [What people search for in marketing: the demand map](https://bravenewhive.com/research/what-people-search-for-in-marketing/): We measured US monthly search volume for every topic a marketing reference site might cover. Three findings. Film titles are the largest entries by a wide margin, concept names beat author names by roughly two hundred to one, and two categories we had planned barely exist as searches. Our own data, fetched 14 September 2026. ## Movies about advertising - [Thank You for Smoking (2005)](https://bravenewhive.com/movies-about-advertising/thank-you-for-smoking/): Jason Reitman's satire follows a tobacco lobbyist who can argue any side of any question. It is a film about spin, about the gap between persuasion and truth, and about what happens to a person who is very good at the first and indifferent to the second. - [The Founder (2016)](https://bravenewhive.com/movies-about-advertising/the-founder/): Ray Kroc turns a single hamburger stand in San Bernardino into McDonald's. The product was the brothers'. The system was theirs too. The brand, the real estate and the name became his. It is the best film ever made about what a brand actually is, and it is not a flattering answer. - [Art & Copy (2009)](https://bravenewhive.com/movies-about-advertising/art-and-copy/): Doug Pray's documentary on the creative revolution in American advertising, with Lee Clow, George Lois, Mary Wells Lawrence, Hal Riney and others talking about the work that defined the trade. It is the most affectionate film on this list and the least critical. - [The Greatest Movie Ever Sold (2011)](https://bravenewhive.com/movies-about-advertising/the-greatest-movie-ever-sold/): Morgan Spurlock makes a documentary about product placement, funded entirely by product placement, and films himself selling the sponsorships. The premise is a gimmick and the footage of the actual sales meetings is the most honest thing ever recorded about how brand partnerships are negotiated. - [The Century of the Self (2002)](https://bravenewhive.com/movies-about-advertising/the-century-of-the-self/): Adam Curtis's four-part BBC documentary on how Freud's ideas about the unconscious were taken up by business and government to manage the public. The most useful thing on this list, and the only one that is really about marketing rather than about advertising people. - [How to Get Ahead in Advertising (1989)](https://bravenewhive.com/movies-about-advertising/how-to-get-ahead-in-advertising/): Bruce Robinson's film in which an advertising executive, unable to write a campaign for a spot cream, has a breakdown and grows a talking boil on his neck that argues for the industry he has come to hate. It is the only genuinely angry comedy about advertising, and it is about what the work does to the person doing it. - [The Joneses (2009)](https://bravenewhive.com/movies-about-advertising/the-joneses/): A family moves into an affluent suburb and is admired for their taste, their possessions and their apparent ease. They are not a family. They are a unit of stealth marketers, placed to make their neighbours want what they have. The premise is better than the film, and the premise is worth an hour of anyone's attention. - [Mad Men (2007 to 2015)](https://bravenewhive.com/movies-about-advertising/mad-men/): Matthew Weiner's series about a New York advertising agency in the 1960s. It is the most influential depiction of our trade ever made, it is extremely good, and it is a period drama that a surprising number of people in marketing have quietly absorbed as a documentary. - [Putney Swope (1969)](https://bravenewhive.com/movies-about-advertising/putney-swope/): Robert Downey Sr's satire in which the token Black executive at a New York advertising agency is accidentally elected chairman, fires almost everyone, renames the firm Truth and Soul, and refuses to take tobacco, alcohol or war toy accounts. It is the angriest film on this list and the most interesting. ## Songs - [This Note's for You. Neil Young (1988)](https://bravenewhive.com/songs/this-notes-for-you/): A refusal to sell songs to sponsors, with a title that parodies a beer slogan. MTV initially declined to air the video, then gave it Video of the Year in 1989. It is the clearest artefact of the moment when musicians had to decide whether sponsorship was selling out. - [Sell Out. Reel Big Fish (1996)](https://bravenewhive.com/songs/sell-out/): A ska-punk band signs to a major label and writes a hit about signing to a major label. The commercial bargain, sung cheerfully from inside it. It is the funniest entry in this section and the one that best describes how the argument actually ended. - [Television, the Drug of the Nation. The Disposable Heroes of Hiphoprisy (1992)](https://bravenewhive.com/songs/television-the-drug-of-the-nation/): Michael Franti's spoken-word indictment of broadcast media, consumption and attention, written before the feed replaced the channel. It is the most analytically serious song in this section and the one that has aged into something closer to prophecy than protest. - [Money. Pink Floyd (1973)](https://bravenewhive.com/songs/money/): Roger Waters on greed, written by a band about to become extremely rich from it. The irony was noted at the time, including by Waters, and the song is more interesting for that than for its argument. - [Material Girl. Madonna (1984)](https://bravenewhive.com/songs/material-girl/): A song about valuing men by their money, performed by an artist who then spent four decades demonstrating control over her own commercial image. The song is slight. What happened around it is the reason it belongs here. - [Advertising Space. Robbie Williams (2005)](https://bravenewhive.com/songs/advertising-space/): A song about the afterlife of a famous person's image, and what happens to it once they are no longer there to object. The commercial subject is posthumous licensing, which is a real and growing industry and is almost never written about. - [Don't Believe the Hype. Public Enemy (1988)](https://bravenewhive.com/songs/dont-believe-the-hype/): Chuck D attacking the media's account of his own group, from an album that argued the press was not a neutral narrator but a participant with interests. It is the best song ever written about media relations, which is not a crowded field. - [Radio Radio. Elvis Costello (1978)](https://bravenewhive.com/songs/radio-radio/): An attack on commercial radio as a gatekeeper, from an artist who then performed it on live American television after being told not to. The performance is more famous than the song and both belong here. ## Reference pages - [Library](https://bravenewhive.com/library/): every source cited across the Hive, deduplicated, with the entries that cite each one. - [A to Z](https://bravenewhive.com/a-z/): every entry, alphabetically.
