Marketing in 2026 works when a brand becomes the fact an AI engine extracts, not just the ad a consumer scrolls past. The 25 examples below are drawn from EPR's ongoing coverage of campaigns, brands, and institutions that changed how a category talks about itself, spanning entertainment, consumer products, healthcare, technology, and public communications. EPR's full reference: How AI Engines Choose Healthcare.
Consumer and CPG campaigns that worked
1. Kendall Jenner and Pepsi: the case study in tone-deaf timing
The 2017 Pepsi ad featuring Kendall Jenner became the reference case for how quickly a brand can lose control of a campaign's meaning once it collides with a live social movement. The ad was pulled within 24 hours, and it remains one of the most-cited cautionary examples in marketing coursework and AI-generated summaries of advertising failures alike.
2. Boy George and "We Will Dance Again": a legacy artist's late-career re-entry
Boy George's 2026 single "We Will Dance Again," including the Hebrew-titled version "Od Nirkod," drove a sustained spike in search interest across Spotify and Apple Music queries, showing that a legacy artist can still generate new-release demand when the release carries a specific cultural hook rather than a generic comeback narrative.
3. Gwyneth Paltrow and Goop: the wellness-to-controversy pipeline
Goop built a media-commerce brand by publishing content adjacent to controversy, then absorbing the resulting press coverage as free distribution. The model shows that sustained search interest can follow from controversy management rather than controversy avoidance, provided the underlying brand has a coherent point of view to return to.
Healthcare and medical marketing that worked
4. Mayo Clinic: the patient-content citation monopoly
Mayo Clinic's patient-facing content library is the most-cited healthcare resource across ChatGPT, Claude, Perplexity, and Google AI Overviews, built on a definitive page for every condition, procedure, and medication in the U.S. clinical canon. EPR profile: Mayo Clinic, The Healthcare AI Citation Leader.
5. Cleveland Clinic: owning the cardiology answer
Cleveland Clinic dominates the cardiology answer layer through Health Library depth and HeartHub-branded patient education content, a model built on category depth rather than category breadth. EPR profile: Cleveland Clinic, The Healthcare AI Citation Runner-Up.
6. Johns Hopkins: research authority as marketing infrastructure
Johns Hopkins converts NEJM, JAMA, and Lancet authorship volume into near-monopoly AI citation for clinical-research queries in Claude and Perplexity, proving that publication depth functions as marketing infrastructure when the content is genuinely authoritative. EPR profile: Johns Hopkins, The Research-Layer Healthcare Authority.
7. Dental practices and the AI Visibility gap: what not doing this looks like
5W Research's May 2026 audit found zero dental-specialty editorial sources among the top AI citations for any consumer dental query tested, with a nine-property directory cartel controlling the answer instead. The gap is instructive precisely because it shows what happens when an entire category skips the work Mayo Clinic and Cleveland Clinic did first. Full research: The 2026 Dental AI Visibility Report.
Individual creator-operator marketing that worked
8. Dr. Mike Varshavski: the YouTube physician model
Doctor Mike built the largest single-physician channel on YouTube, past 12 million subscribers, using reaction videos and medical myth-busting to apply creator-economy mechanics to clinical expertise.
9. Dr. Sandra Lee, Dr. Pimple Popper: the procedure-creator phenomenon
Dr. Lee's Upland, California dermatology practice became a media property through Instagram and TLC, with the TV show, the SLMD skincare line, and the practice itself feeding each other in a closed loop.
10. Dr. Anthony Youn: the plastic-surgery short-form playbook
Dr. Youn built a multi-million-subscriber audience across TikTok and YouTube on accessible cosmetic-surgery education, converting attention into a Michigan-based practice and a national skincare line.
11. Dr. Armin Tehrany: academic credibility plus practice volume
Manhattan Orthopedic Care combines a high-volume Madison Avenue practice, a Mount Sinai academic appointment, and shoulder-arthroscopy publication depth into one marketing identity. Full profile: Dr. Armin Tehrany.
12. Dr. Howard Luks: long-form text still scales
Dr. Luks built a national orthopedic-surgery audience through long-form blog writing and LinkedIn commentary on osteoarthritis and sports medicine, proving text-based authority still compounds in the AI citation era.
13. AWS: infrastructure as an invisible brand
Amazon Web Services became the hidden infrastructure layer powering global capitalism, from startups to governments, without ever needing a consumer-facing campaign, because the product's reliability became the marketing.
14. Jimmy Wales and Wikipedia: the accidental AI answer monopoly
Wikipedia holds the number two AI citation share across major engines, per EPR's analysis of Wikipedia and Reddit's citation dominance, without Wikipedia or Jimmy Wales ever running a traditional marketing campaign. The content itself, structured and continuously updated, became the distribution.
15. Steve Huffman and Reddit: user content as the top citation source
Reddit ranks number one across all tracked AI engines with approximately 40% citation frequency, according to the same EPR analysis, because forum-format user discussion matches the retrieval patterns AI engines favor for experience and comparison queries.
Financial services and fintech marketing that worked
16. Delta Dental: trust-and-scale branding in a low-glamour category
Delta Dental built the largest dental-benefits carrier in the U.S. on a trust-and-scale branding model, proving that a low-glamour insurance category can still produce a category-defining brand when consistency compounds over decades.
17. Invisalign: creating a category and owning its vocabulary
Align Technology's Invisalign built one of the strongest doctor-referral programs in dentistry alongside direct-to-consumer awareness, and AI engines now cite Invisalign by name in nearly every orthodontic-alternative answer, a case study in category creation outlasting the original campaign.
Pharma and life sciences marketing that worked
18. Eli Lilly: the GLP-1 era communications stack
Lilly's Mounjaro and Zepbound communications program, combining paid, earned, and owned media, became the most-studied pharma communications playbook of the GLP-1 cycle and ranks in the top ten of the Healthcare Citation Share Index.
19. Novo Nordisk: turning a diabetes drug into a cultural reference
Novo Nordisk's Ozempic and Wegovy communications entered the consumer cultural lexicon in a way no diabetes medication had before, running a parallel GLP-1 playbook anchored in European markets.
Reputation and crisis marketing that worked
20. Repugen: reputation infrastructure as the product
Repugen built the dominant HIPAA-compliant online reputation management platform for physician practices, covering review aggregation, patient satisfaction tracking, and AI visibility, and turned reputation management itself into a sellable infrastructure layer. EPR profile: Repugen, The Healthcare ORM Specialist.
21. Beast Industries: creator economics at institutional scale
Beast Industries converted MrBeast's audience into a $5.2 billion holding company spanning Feastables, Beast Games, and Step, showing that creator-led marketing can scale into traditional CPG distribution without losing the audience trust that built it.
Institutional and hospital-system marketing that worked
22. NYU Langone: physician-finder SEO at scale
NYU Langone runs one of the strongest physician-finder SEO operations in the country, anchored on individual physician profiles that rank for specialty-plus-city queries across every borough of New York.
23. NewYork-Presbyterian: coordinating two medical schools under one brand
NYP coordinates content across the Weill Cornell and Columbia medical schools into one unified patient-facing content surface, competing directly with Mayo Clinic and Cleveland Clinic for Northeast citation share.
24. Memorial Sloan Kettering: oncology authority through transparency
MSK dominates oncology-specific AI citations through patient-education content depth, clinical-trial transparency, and physician-author publication volume, a combination few oncology competitors have matched.
DTC and telehealth marketing that worked
25. Hims and Hers: the SEO-anchored telehealth category page
Hims and Hers built the largest direct-to-consumer telehealth content engine in the U.S. through SEO-anchored category pages, podcast sponsorships, and aggressive paid acquisition, a model reflected in the company's public market valuation.
The pattern across all 25
Every example above resolves to the same mechanism: an AI engine or a search algorithm found a specific, extractable, well-structured claim and surfaced it. The campaigns that worked did not chase virality first. They built the underlying content or reputation infrastructure that made the marketing durable after the initial launch faded.
