This is the earliest version of web, often referred to as static web or read-only web. In this version there were only readable contents available in the form of text and images. It was only a one way broadcast of information by businesses. End-users could only search information and read it. It was not possible for end-user to interact with the information like post an update or a picture, update comments etc.
Web 1.0 had one publisher and multiple consumers of static data.
E.g. Shopping experience in web 1.0 era. User sees advertisement about a product on the website. Visits the store for buying it as interaction is not possible through website to shop online.
To solve the Web 1.0 limitations of one publisher and multiple consumers, static data another version of web came into existence. This version of web is referred to as participative social web. As the name refers, it is an interactive form of web where end-users can participate over web to collaborate and share information for free through various platforms such as blogging, podcasting, social media content etc.
E.g. Shopping experience in web 2.0 era. User creates an account in shopping website, searches items of his choice. Adds the item to cart and checks out by opting out payment options.
The advantage of dynamic data, 2-way communication between publishers and consumers. But all this works at the cost of loosing privacy. Because when you are logged in to shopping website which has tie-ups with social media sites for generating traffic. As policy of website, you agree to terms and conditions while sign in which has a clause to share your personal data and information.
This version of web is referred to as read write execute web. Web 3.0 will enable 2-way interaction of the user with the product, eliminating the requirement of a middleman. Users have the right to remove the ads if they don’t want to watch. If they see it, the browser distributes the rewards to users generated on the ad.
It will eliminate the monopoly of big social media sites upholding users data, where users have no right to remove the ads. If they wish to do so, they are charged money for blocking the ads. Data breach, one of the crucial problems in the existing web 2.0 generation, will be eliminated.
E.g., Shopping experience while maintaining privacy
Though, Web 3.0 has advantages which solves the problem of maintaining anonymity, eliminates the middle agent, gives the power of the internet in public hands and makes it decentralized, it has certain other challenges such as unethical and illegal acts, global warming at ground level, lack of effective tracing mechanism of source of broadcast due to anonymity.
