XHTML 1.0

After the release of HTML 4.01, the W3C shifts its focus to XHTML, a standard that blends the syntax and rules from XML with the properties of HTML. XHTML strictly enforces its ruleset, which makes it interoperable, but more difficult to implement in browsers.

SOAP And REST At Odds

Simple Object Access Protocol (SOAP)

SOAP is developed at Microsoft as a web services platform for servers and clients to communicate with one another. SOAP encodes messages in XML and transfers them over a common envelope. SOAP is action driven, meaning a separate endpoint handles each operation the server needs to make.

Doctype Switching and the Box Model Hack

While developing IE5 for Mac, Tantek Çelik introduces doctype switching, allowing web developers to define which CSS box model to use in modern browsers. To polyfill older browsers, he creates the Box Model Hack, which uses some CSS to define widths for both box models in the same definition.

Amazon Web Services (AWS)

Amazon unveils a set of tools for developers, including an XML API, and calls it Amazon Web Services. At first, these tools allow developers to pull data from Amazon to use on their own site, but it will slowly evolve to become a complete solution for cloud infrastructure and hosting on the web.

Designing with Web Standards

New Riders Press publishes Designing with Web Standards by Jeffrey Zeldman, a handbook that helps designers transition from table-based hacks to HTML and CSS based designs. It offers a pragmatic approach for getting started with web standards and acts as a jumping off point for a lot of web designers.

Atom Syndication Format

After RSS went unchanged for several years, some members of the web community decided to create a new syndication format that was better suited to the growing needs of the web. Atom is released after a few months of discussion on a public wiki, and the format eventually becomes and IETF standard.

Mozilla Foundation

The Mozilla Organization is spun off into a non-profit called the Mozilla Foundation. The group had been operating from within Netscape for some time, but making the organization independent ensured it could continue to operate even if Netscape didn’t.

Delicious

Joshua Schachter and Peter Gadjokov launch Delicious, a social bookmarking platform.

The Power of the Pixel

YouTube

Former Paypal employees Steve Chen, Chad Hurley, and Jawed Karim launch their video sharing platform YouTube.

Even early on, it makes videos easy to upload, and includes a cross-platform video player.

Launched by Alex Tew, the Million Dollar Homepage lays out a grid of a million pixels, and sells each to advertisers for a dollar. The site is an early example of an Internet phenomenon that spreads quickly to millions of users.

iPhone

Steve Jobs and Apple unveil the iPhone at Macworld. It is notable for a number of its technological achievements, not the least of which is a full-featured mobile web browser with the latest HTML and CSS support. Over the years, the iPhone would both influence and be influenced by the web’s development.

A side project of Japanese web design agency Tha, FFFFOUND! sends out invites to a handful of users. FFFFOUND! allows users to post images from across the web, and connect them with other pictures through likes and comments. FFFFOUND! would soon gather a loyal following of users looking for inspiration or art.

Purple, Obama, and Single Serving Websites

Single Serving Sites

Jason Kottke gives a name to sites that have a single purpose and a URL that speaks for itself. Kottke was inspired by BarackObamaIsYourNewBicycle.com, and wrote an article gathering similar  examples. From there, the phenomena of single serving sites only grew as more and more were added to the web.

The Archive Team

Jason Scott rounds up a group of volunteers to help download and archive all of Geocities before it is deleted. In the wake of their successful recovery of Geocities, Scott forms the Archive Team to support a collective archiving effort whenever a site is threatened by deletion.

Pinboard

Pinboard is launched as a lightweight competitor to Delicious by Maciej Cegłowski and Peter Gadjokov (one of Delicious’ co-founders), with a focus on private sharing and a focused feature set. When Pinboard goes up, it’s price is $3, which increases a fraction of a cent each time a user signs up.

Typekit

Small Batch launches Typekit at a time when web fonts in browsers are spotty and uneven. Typekit allows font foundries to sell digital licenses directly to web developers, and gives developers an easy way to embed them on their site. In 2011, Typekit will be bought by Adobe.

WOFF File Format

CSS Modules

With the release of CSS3, CSS was divided into several different specifications known as “modules”. Each module represented a subset of CSS, such as colors or web fonts, and is operated and maintained by an independent working group, so that each can advance at its own pace.

HTML Splits In Two

After working together for a few years, the W3C and WHATWG officially agree to approach HTML differently. The W3C would, from time to time, record a “snapshot” and continue to increment versions of HTML (5, 6, etc). The WHATWG, on the other hand, would adopt a single “living standard,” just called HTML.

HTML5 Official Recommendation

HTML5 is formally made a recommendation by the W3C. HTML5 adds new syntactic elements and attributes, deeper APIs, and more access to native features. It also includes much broader support for multimedia and web graphics with elements like video and canvas.

Place

An April Fools joke launched by Reddit, Place invites users to change pixels on a large, shared grid. But each user can only edit a single pixel every 5 minutes, meaning cooperation and a massive team effort followed the three days the site was in operation.

Adobe announces that as of 2020, they will stop supporting and updating Flash software and players. After the release of the iPhone and other mobile devices sans Flash, much of the web moved away from the technology, though it is still frequently used by indie animators and game developers.
