How do Standards Bodies Operate?

The open web does not run itself. Every time a browser renders a page, plays a video, or draws a 3D scene, it is following instructions that were set over the years by engineers and company representatives sitting in working groups. These instructions are called web standards. And the groups responsible for setting them are called standards bodies. Think of them as the legislators of the internet. The organizations that do most of the work in web standards today include the **W3C**, the **WHATWG**, **ECMA (TC39)**, and the **Khronos Group**. Each of them governs a different layer of the stack, and each operates a little differently. **The Web Hypertext Application Technology Working Group**, WHATWG, maintains HTML and the DOM as a single continuously updated "living standard." Rather than versioned releases, the specification evolves in real time, edited by a small group with strong editorial authority. Decision-making power sits with the major browser engine teams like Chromium, Gecko, and WebKit. **The World Wide Web Consortium**, W3C, is the primary standards organization of the web. It has a broad membership across browser vendors, governments, and research institutions. W3C oversees CSS, SVG, accessibility guidelines, and numerous web APIs. It works through a slow, agreement-driven process where proposals pass through multiple stages of review before becoming official standards. **Ecma International** (formerly the European Computer Manufacturers Association, or ECMA) is a general-purpose standards organization originally focused on computing and communications technologies. Today, it formally publishes the ECMAScript standard, which JavaScript implementations are based on. The technical development of the language standard is carried out by Ecma’s Technical Committee 39 (**TC39**), while Ecma International provides the organizational framework, publication process, and standards governance. The committee meets roughly every two months with delegates from Google, Apple, Mozilla, Microsoft, and others. New language features move through a five-stage proposal process, from a rough sketch at Stage 0 to fully specified and implemented at Stage 4. Features like async/await, optional chaining, and ES modules all went through this process before landing in the JavaScript language. The **Khronos Group** is a member-funded consortium focused on graphics, compute, and media standards. The members include delegations from GPU manufacturers like NVIDIA and AMD, alongside browser vendors. For the web, its most significant contributions are WebGL and WebGL 2, which bring GPU-accelerated 3D rendering to the browser.
