TL;DR:MLB's "My Daily Story" uses AI to create millions of personalized highlight reels daily—turning scattered fan attention into engaged daily habits. You'll want this playbook for your customer engagement strategy.

🎯 AI IN ACTION

The Bottom of the Ninth: When Fan Engagement Strikes Out

Picture this: You're MLB, sitting on a goldmine of 15 million data points per game across 30 teams and 4,000+ annual events. Your fans are drowning in content—scrolling endlessly through generic highlights, missing the moments that matter most to them. Sound familiar? That's exactly the challenge every business faces in today's attention economy.

"In an attention economy, you need to compete even harder to earn someone's time. As a consumer, I only have a certain amount of time in the day. Why waste it on something I'm not interested in?" - Josh Frost, MLB's Senior Vice President of Product

MLB's decade-long investment in fan experience technology had hit a wall. Despite having sophisticated recommendation engines, fans were still playing digital hide-and-seek with content they actually wanted to watch.

Watch New Way Now: MLB Case Study

The AI Curveball: From Machine Learning to Generative Magic

Here's where MLB threw a technological curveball that would make any executive jealous. Instead of just tweaking their existing systems, they went full AI transformation with Google Cloud's arsenal.

"It's the step change from machine learning to AI to generative AI. We can deliver a much more enhanced experience, combining traditional programming with machine learning and gen AI."

The evolution was like watching a rookie become an MVP:

  • Stage 1: Machine learning sorted highlights by teams and clip types
  • Stage 2: AI recommendation engines suggested relevant content
  • Stage 3: Generative AI creates millions of unique, cohesive daily stories

Using gen AI, their systems have a better understanding of what fans are engaging with. They're able to fine-tune recommendations and algorithms based on what people watch and don't watch to better deliver what people are interested in seeing.

Reading Between the Lines: Explicit and Implicit Fan Signals

While MLB tracks obvious preferences like favorite teams and followed players, the implicit signals revealed fascinating fan psychology patterns that most businesses completely miss.

"We talked a lot about explicit signals like players and teams. But the implicit signals we've found a lot of engagement on have been really cool to see, too. For example, people that love pitching want to see a pitch that starts up here and curves down, and the batter has no clue on how to swing at it. Some people appreciate speed, some people just want to see a home run go 450 feet to dead center."

The system reads both explicit signals (favorite teams, followed players) and implicit ones (viewing behavior, play preferences). Love 450-foot home runs? The AI knows. Obsessed with curveballs that leave batters clueless? It's got you covered.

The Tech Stack That Swings for the Fences

MLB didn't just sprinkle some AI fairy dust and call it a day. They built a sophisticated system using Google Cloud's Vertex AI, Video AI, BigQuery, and generative AI that would make any CTO weep with joy.

Here's the play-by-play of their technical approach:

  • Hawk-Eye tracking systems capture data on every single pitch
  • Neural networks and computer vision distinguish between fastballs, curveballs, and home runs
  • Metadata tagging breaks down and categorizes different types of video content
  • Generative AI augments descriptions in English and Spanish for global scale
"We have metadata that helps break down and categorize different types of video content. We do a lot of recording on every single pitch. We have our Hawk-Eye tracking system that helps us capture a lot of that data. We also use neural networks and computer vision to help distinguish between pitch types and give additional color to metadata."

The Million-Dollar Challenge: Scaling Personalization

Here's where most companies would throw in the towel: MLB needed to create millions of unique, cohesive highlight packages daily. Not hundreds. Not thousands. Millions.

"We're not building one homepage or app—we're building thousands, even millions. A human can't really review all of those."

Enter generative AI as the ultimate scaling solution. The technology doesn't just curate content—it creates cohesive narratives that feel hand-crafted for each fan. Even if you can get the correct "playlist" of content, you want it to be a cohesive package.

This is where generative AI comes in—it can help modify and augment the metadata descriptions of plays in English and Spanish. This gives them scale they wouldn't otherwise be able to achieve, creating personalized storytelling at a level that would be impossible for human editors.

The Business Impact: More Than Just Highlights

While MLB hasn't released specific revenue figures for My Daily Story, the strategic impact is clear. The app has achieved all-time high fan engagement and ratings since implementing AI-powered personalization.

The real win? Transforming casual browsers into daily users. My Daily Story creates a "new daily reason for fans to start their journey in the MLB app every morning during the season," turning sporadic engagement into habitual behavior.

For a league processing petabyte-scale data across 30 teams, the operational efficiency gains from AI automation are substantial. Instead of human editors creating thousands of highlight packages, AI generates millions while maintaining quality and coherence.

Lessons from the Dugout

  • Evolution beats revolution: MLB didn't scrap their existing systems—they evolved from machine learning to AI to generative AI, building on each foundation.
  • Scale requires AI: When you need millions of personalized experiences daily, human curation becomes mathematically impossible. AI isn't just helpful—it's essential.
  • Implicit signals reveal hidden value: Don't just track what customers say they want—analyze what they actually engage with. The patterns reveal opportunities you never knew existed.
  • Personalization is the new table stakes: In an attention economy, generic content is a luxury you can't afford. Every touchpoint should feel custom-built for the individual user.

🐯 Tiger Takeaway:

Personalization isn't just a nice-to-have anymore—it's the new MVP for fan engagement and business value. MLB's success with "My Daily Story" proves that when you combine AI's scaling power with deep understanding of both explicit and implicit customer signals, you don't just improve engagement—you transform daily habits. The question isn't whether your customers want personalized experiences. It's whether you're ready to deliver millions of them.
