Markdown, the simple text formatting language John Gruber created for his personal blog in 2004, now controls the entire technology ecosystem. Anil Dash published an analysis on January 9, 2026 revealing that from trillion-dollar AI systems like ChatGPT to everyday tools like Apple Notes, everything runs on the format “one guy made up for his blog.” The scope is staggering: billions of files, every major platform, even 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 Notes, Google Docs, Microsoft Notepad, Slack, WhatsApp, and 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 Fireball, an Apple-focused blog, in 2002 when few people blogged. He needed simple web formatting without HTML’s complexity. Enter Aaron Swartz—17 years old, tech prodigy—as Gruber’s sole beta tester.
Swartz provided critical feedback and wrote html2text, the 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 problem, shared it freely, and walked away. That generosity built internet infrastructure.
Why Markdown Won: Four Critical Success Factors
Anil Dash identified ten success factors. However, four stand out as critical:
Clever branding. “Markdown” inverts “Markup”—immediately understandable to technical and non-technical users alike. The name itself was marketing brilliance. Moreover, it communicated the concept instantly.
Perfect timing. Markdown launched in 2004 when blogging and social media were new. Users already faced a learning curve. Consequently, adding 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. Furthermore, adoption required zero behavioral change.
No IP restrictions. Gruber shared Markdown with zero legal barriers. No patents. No licensing fees. As a result, open adoption exploded because there was nothing to stop it.
Alternatives existed—reStructuredText (more powerful), AsciiDoc (more features), Textile (earlier competitor). Nevertheless, Markdown won on simplicity, not complexity. Sometimes less is more.
From Chaos to CommonMark: Standardization Without Stagnation
Between 2004 and 2014, Markdown fragmented. Multiple “flavors” emerged with incompatible features. Then CommonMark arrived in 2014—a formal specification removing ambiguities, backed by comprehensive tests.
In 2017, GitHub formalized GitHub Flavored Markdown (GFM) as a strict superset of CommonMark, adding tables, strikethrough, autolinks, and task lists. Crucially, extensions remained optional and compatible. Therefore, standardization unified the ecosystem without killing innovation.
Major platforms adopted CommonMark: GitHub, GitLab, Reddit, Stack Exchange, Qt, Swift. That balance—stable baseline, extensible 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 problems, not 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 hoarding, vendor lock-in, commercial exploitation. Markdown proves the opposite works: open sharing, zero restrictions, community benefit. Indeed, the 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 branding, perfect timing (2004 blogging boom), no IP restrictions, human-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 somehow, that became how we control the future of AI.
