Web 2.0

What is Web 2.0?

Web 2.0 is a term used to describe today’s interactive Internet. It is the second generation of the Internet originally created in 1990 by Tim Berners Lee. Web 2.0 features websites and applications based on dynamic web pages and participation in creating user-generated content. This is in contrast with Web 1.0, the earlier Internet of the 1990s, which was based on the passive consumption of content from static web pages.

Web 2.0 is focused on community building and information sharing through social media platforms, while the next generation – Web 3.0 – involves users taking back ownership and control of their personal information from the large corporations that have become dominant in Web 2.0.

Web 2.0 History

The term Web 2.0 was first used in 1999 by information architecture consultant Darcy DiNucci to refer to the evolution of the Internet in an article titled “Fragmented Future“. DiNucci wrote: “The Web will be understood not as screenfuls of text and graphics but as a transport mechanism, the ether through which interactivity happens.”

The term was later adopted in 2004 by Tim O’Reilly and Dale Dougherty of O’Reilly Media at the first Web 2.0 Conference, where they advanced the idea of the Web as a platform.

Key milestones in the emergence of Web 2.0 include the launch of platforms such as MySpace in 2003, Facebook in 2004, YouTube in 2005, and Twitter in 2006, as well as the growth of self-publishing platforms including WordPress, Medium, and Substack, which advanced the transition to social networking and user-generated content.

How Web 2.0 Works

The transition to Web 2.0 was not marked by any specific technical upgrades to the Internet but by a change in how users interact with it.

Web 2.0 operates on technologies that enable the use of rich user interfaces, dynamic content, and social networking. Core technologies include Adobe Flash, Microsoft Silverlight, and JavaScript, in addition to Asynchronous JavaScript and XML (Ajax), Really Simple Syndication (RSS), and Eclipse, which allows developers to create immersive and dynamic user experiences.

Ajax enables different webpage components to be updated separately so that users do not have to reload entire pages each time they refresh. Application programming interfaces (APIs) enable software programs to interact and share data with other applications to offer integrated apps and services.

Rather than simply reading a static web page as in Web 1.0, in Web 2.0 a user can participate and contribute to the content of a website by creating a user account, commenting on blog posts and other types of articles, or uploading their own media.

With tools like AI website builders and e-commerce platforms, anyone can build a website in just a few minutes. Tagging and like buttons enable users to sort content and enable algorithms to deliver the type of content the user prefers to consume.
