Markdownthe simple text formatting language John Gruber created for his personal blog in 2004now controls the entire technology ecosystem. Anil Dash published an analysis on January 92026 revealing that from trillion-dollar AI systems like ChatGPT to everyday tools like Apple Noteseverything runs on the format “one guy made up for his blog.” The scope is staggering: billions of filesevery major platformeven Nintendo Switch consoles.
From AI to Gaming Consoles: Markdown Everywhere
The dominance is absolute. ChatGPT and Claude structure AI prompts in Markdown. GitHub repositories contain billions of README.md files. Apple NotesGoogle DocsMicrosoft NotepadSlackWhatsAppand Discord all support Markdown formatting. Even hardware—Nintendo Switch devices and audio equipment—ships with Markdown documentation.
As Anil Dash notes“trillion-dollar AI companies control their most advanced systems through a plain text format one guy made up for his blog.” That irony captures how far Markdown has spread: from a 2004 blogging tool to the universal interface for controlling cutting-edge AI.
The readability advantage is obvious. Compare <h1>Heading</h1><p>This is <strong>bold</strong> text.</p> (HTML clutter) to this:
# Heading
This is **bold** text.Markdown source is self-documenting—readable without rendering. That’s the foundation of its success.

One Blogger + One Teenage Prodigy = Internet Standard
John Gruber started Daring Fireballan Apple-focused blogin 2002 when few people blogged. He needed simple web formatting without HTML’s complexity. Enter Aaron Swartz—17 years oldtech prodigy—as Gruber’s sole beta tester.
Swartz provided critical feedback and wrote html2textthe HTML-to-Markdown converter. His earlier atx language (2002) influenced Markdown’s # heading syntax. The collaboration was unconventional: established blogger plus teenage genius. Yet it worked. Markdown launched in 2004 and changed everything.
Gruber never patented it. No licensing fees. No commercial exploitation. He solved a personal problemshared it freelyand walked away. That generosity built internet infrastructure.
Why Markdown Won: Four Critical Success Factors
Anil Dash identified ten success factors. Howeverfour stand out as critical:
Clever branding. “Markdown” inverts “Markup”—immediately understandable to technical and non-technical users alike. The name itself was marketing brilliance. Moreoverit communicated the concept instantly.
Perfect timing. Markdown launched in 2004 when blogging and social media were new. Users already faced a learning curve. Consequentlyadding Markdown wasn’t a burden—it was part of the package. Timing mattered more than features.
Familiar behaviors. Markdown drew from decades of email formatting conventions. People unknowingly wrote Markdown in emails (*emphasis*-lists) for years. Formalization felt natural. Furthermoreadoption required zero behavioral change.
No IP restrictions. Gruber shared Markdown with zero legal barriers. No patents. No licensing fees. As a resultopen adoption exploded because there was nothing to stop it.
Alternatives existed—reStructuredText (more powerful)AsciiDoc (more features)Textile (earlier competitor). NeverthelessMarkdown won on simplicitynot complexity. Sometimes less is more.
From Chaos to CommonMark: Standardization Without Stagnation
Between 2004 and 2014Markdown fragmented. Multiple “flavors” emerged with incompatible features. Then CommonMark arrived in 2014—a formal specification removing ambiguitiesbacked by comprehensive tests.
In 2017GitHub formalized GitHub Flavored Markdown (GFM) as a strict superset of CommonMarkadding tablesstrikethroughautolinksand task lists. Cruciallyextensions remained optional and compatible. Thereforestandardization unified the ecosystem without killing innovation.
Major platforms adopted CommonMark: GitHubGitLabRedditStack ExchangeQtSwift. That balance—stable baselineextensible features—kept Markdown adaptable.
Internet Infrastructure Runs on Generosity
Here’s what Dash’s analysis reveals: most foundational internet technologies emerged from individuals solving personal problemsnot corporations chasing profits. Gruber created Markdown for his blog. Swartz helped refine it. Neither sought financial returns. Both changed how billions of people format text.
Contrast that with today’s extraction capitalism—IP hoardingvendor lock-incommercial exploitation. Markdown proves the opposite works: open sharingzero restrictionscommunity benefit. Indeedthe result is a 22-year-old format that powers trillion-dollar AI systems.
As Dash puts it“internet infrastructure fundamentally depends on generous contributions from regular people rather than five terrible tycoons.” Markdown is proof.
Key Takeaways
- Markdown conquered the entire tech ecosystem—from ChatGPT to GitHub to Apple Notes to Nintendo Switch
- Success factors: clever brandingperfect timing (2004 blogging boom)no IP restrictionshuman-readable source
- Gruber + Swartz (age 17) collaboration created internet infrastructure without commercial motive
- CommonMark (2014) and GitHub Flavored Markdown (2017) standardized fragmented variants while preserving innovation
- Lesson: Open generosity beats commercial extraction—individual problem-solving can transform industries
The next time you format ChatGPT prompts with ## headings and **bold**remember: you’re using a format one blogger made up for his website. And somehowthat became how we control the future of AI.
