W3C (World Wide Web Consortium) founded by Tim Berners-Lee in 1994 to maintain open web
standards.

4️⃣ HTML 4.01 (1999)
- Better forms, scripting, frames, accessibility

- WHATWG introduced the "Living Standard" (no more version numbers)

HTML = Language of the web (structure + content)
W3C = Maintains HTML standards
WHATWG = Develops HTML as a Living Standard now
