A Short History of Web

The Web, or World Wide Web as we know it today, has a long and complex history that spans several decades. Here is a detailed history of the Web and how it has evolved into what we call Web 1.0, Web 2.0, and Web 3.0.

Web 1.0

The Web was born in 1989 when computer scientist Tim Berners-Lee proposed a way for people to access and share information over the internet. The first website went live in 1991 and was a simple page with links to other pages. The Web grew rapidly from there, and by the mid-1990s, there were millions of websites online.

Web 1.0 was characterized by static web pages that provided information to users but didn’t allow for much interaction. Web pages were created using HTML and displayed in web browsers like Netscape Navigator and Internet Explorer. Websites were primarily used to disseminate information, and users had limited control over the content they viewed.

Web 2.0

Web 2.0 emerged in 2004 as a response to the limitations of Web 1.0. Web 2.0 was characterized by interactive web applications that allowed users to create and share content. Social networking sites like Facebook and MySpace, video-sharing sites like YouTube, and blogging platforms like WordPress emerged during this period.

The rise of Web 2.0 led to a new era of user-generated content and social interaction on the Web. Web 2.0 applications were built using more advanced programming languages like Javascript and PHP. They used APIs and web services to connect to other web-based services.

Web 3.0

Web 3.0 is often referred to as the ‘Semantic Web’ and is characterized by an increased focus on machine-readable data and artificial intelligence technologies. Web 3.0 seeks to make the Web more intelligent and intuitive by providing users with personalized, context-sensitive information.

The goal of Web 3.0 is to create a more intelligent and connected Web that makes it easier for users to find the information they need and interact with each other in meaningful ways. Web 3.0 applications are built on HTML5, CSS3, and Javascript technologies. They use advanced analytics and machine learning algorithms to provide users with tailored content and recommendations.
