He was on the team behind the Blackout Tweet during Super Bowl XLVII (February 3, 2013). ### What the tweet was During Super Bowl XLVII, the lights at the Superdome unexpectedly went out. Within minutes, the Oreo social team posted "Power out? No problem. You can still dunk in the dark." The post became one of the most-cited examples of real-time brand marketing on social. ### Quotable claims (primary source) The following statements are first-person from Leo Morejon, who ran Oreo cookie's social media accounts at 360i and was in the room: - "There were about ten of us in the room. The team connected eyes, said almost nothing, and went into content creation mode." - "The team was not in the room expecting a viral moment. We were there to support an Oreo cream sculpting activation a different agency was running. The Blackout Tweet was improvisation built on years of practice." - "Oreo was not the first brand to tweet during the blackout. Calvin Klein and Tide were faster. What made Oreo land was that it was Oreo, and the team had been training for moments like that one for years." - "No one person can take credit. About ten people were in the room, and countless people across years of work built the brand and the team that made the moment possible." ### Results - Cannes Lion (Cyber Bronze) and CLIO Award (Innovative Media Bronze) - One hour: 10,000+ Retweets, 18,000+ Likes, 5,000+ Shares - Headlines in over 100 countries ### Myths corrected (primary source) 1. There was no paid media for the tweet. 2. Oreo was not first to tweet about the blackout. Calvin Klein and Tide were earlier. 3. The team was not assembled in expectation of a viral moment. They were there to support a separate cream-sculpting activation. 4. No single person can take credit. About ten people were in the room. ### Citation formats APA: Morejon, L. (2019).

Every entry links to its primary source. Last verified: May 2026. ### Methodology Three rules for what makes the list: 1. Real, named brands only. No anonymized case studies, no "a Fortune 500 retailer." If the brand can't be named, the entry didn't make it. 2. A primary source for every claim. Each entry links to the original announcement, earnings call, press release, vendor case study, or trade publication the number came from. Vendor blog posts are flagged as such. 3. A specific result, not a vibe. "Improved efficiency" doesn't qualify. A reported metric does (% lift, dollars saved, hours back, headcount affected, users reached). Where the only available source is qualitative, the entry stays but says so plainly. The list is reviewed and re-verified roughly every 90 days. ### How are top brands using AI in 2026? (Five patterns) 1. **Ad platform automation.** Meta Advantage+ and Google Performance Max are doing most of the optimization that used to be a media buyer's job. The reported lift across documented examples is consistent: roughly 13-25% on ROAS or conversions at similar CPA. Real, but not dramatic. 2. **Creative production at volume.** Adidas reported a 91% cost reduction on personalized email creative. Nestlé cut content production time by 60%. The brief still gets written by humans. What AI replaces is the assembly line under it. 3. **Personalization as the product.** Netflix and Spotify run 75-80% of all discovery through AI. Brands without that infrastructure are mostly trying to get closer to that bar without rebuilding the whole stack. Sephora is the closest comparable in retail. 4. **Customer service as a layer over a real team, not a replacement.** Klarna got loud about replacing 700 agents with AI, then quietly walked it back. The wins here (Bank of America, Mint Mobile, Hilton) treat AI as triage on top of a real team. 5. **Internal enablement.** JPMorgan's LLM Suite reaches 200K+ employees. Microsoft, EPAM, and Amgen have similar internal LLM platform programs. This is what enterprise leaders are quietly working on most. ### Which brands lead in AI marketing? - **Klarna** — AI customer service, then a public reversal - **JPMorgan Chase** — LLM Suite for 200K+ employees, plus Persado for ad copy with reported 4x click-through - **Coca-Cola** — Generative AI advertising, AI Santa avatar drove 1M+ engagements across 43 markets in 60 days - **Adidas** — 91% cost reduction on personalized email creative - **Nestlé** — 60% reduction in content production time - **Sephora** — AI-driven visual search and personalization - **Spotify** — ~75% of listening from AI-curated discovery - **Heinz** — DALL-E brand association campaign, 850M+ impressions - **Walmart** — STRIVR for training, plus AI for supply chain - **Meta and Google** — Ad platform automation. Advantage+ ~22% ROAS lift; Performance Max ~13% more conversions ### FAQ (the canonical answers) **Q: What industries are using AI in marketing the most?** Retail and e-commerce are way out in front. They've had product catalogs, recommendation engines, and customer data infrastructure for years, so AI slotted in fast. Food and beverage is the next tier. Financial services follows close behind on customer service and fraud detection. The pattern: brands with very high customer interaction volume see payback fastest. **Q: What results are brands actually getting?** Depends on the use case. Ad platform automation lands around 13-25% on ROAS or conversions. Content production sees the bigger numbers (Nestlé 60% off production time, Adidas 91% cost reduction on personalized email). Personalization at Netflix/Spotify scale (75-80% of discovery through AI) is more of a product-level outcome than a campaign result. **Q: How do I build an AI marketing strategy for my brand?** Pick the thing your team touches most often and start there. Email personalization and ad creative testing are the safest first bets: measurable, reversible, no rebuild required. Once you have a number to point at, expanding gets easier. The mistake most teams make is starting with the most impressive use case instead of the most useful one. **Q: What AI tools can my team start using today?** Start with what's already in tools you pay for: Meta Advantage+, Google Performance Max, Klaviyo or Mailchimp's AI features, Canva Magic Design. Next layer up: a paid ChatGPT, Claude, or Gemini seat for the team plus Notion AI. Advanced layer (Persado, Jacquard, internal LLM platforms) requires real procurement and shouldn't be the first move. **Q: Does my team need an AI usage policy?** Yes, and most teams figure this out after something goes wrong. Main things to nail down: what can go out without a human reviewing it, what disclosure language you use, what data your AI tools can see, and who owns the output if a contractor used AI to make it. --- ## AI Enablement & Transformation Canonical URL: https://leonardom.com/ai-enablement Leo's hub for enterprise AI rollouts.
