One of the most important moments for the internet is the surge of the Web 2.0. This concept has evolved from a previous one called Web 1.0. But what is Web 2.0 and why is so important? To explain this, first we have to understand what Web 1.0 is.

Web 1.0 is the concept that defines a direct interaction between producer and consumer through internet. This interaction only goes from producers to consumers sharing static information. It has a top-down approach where users can only view web pages but they cannot reflect on its content. The information is not dynamic; most of the users act as consumers of content and the information is closed to external editing.

Web 1.0 evolved to Web 2.0. This change opened the door for the information sharing. Web 2.0 uses the World Wide Web as a platform not only for sharing information, but also for interoperate based on a user-centered design. This evolution also brought numerous forms of interaction. Some examples are social networking, blogs, video sharing, web applications, wikis, storage data and mashups. 

This information sharing system changed the view of internet as a platform of communication. It gave power to the consumers, not only to view information from producers, but also to make comments about products and services, to give their opinion and share it to their community. This changed the way producers communicate with consumers and how they create products for the market. Everything started to be consumer and user centered.

Advertising evolved from being just static information to include the cost per click. Users can decide if they want to find out more about the offering. Internet and social networking became an important media for companies.

After this emergence of Web 2.0 on the internet revolution, started the phenomenon of Social Media. Facebook is the leader of social networking. This represents another important moment for the history of the web. Social Media allows people to stay connected and share day-to-day information, becoming the most popular online activity. People use social media platforms to share videos, pictures, news and any other event. This was a consequence of the open concept of interactive sharing information.

Web 2.0 is also evolving to a new concept called Web 3.0. In this case, the information becomes more personal. Web 1.0 was passive interacting with static information, Web 2.0 is active based on intelligence shared and now Web 3.0 is about artificial intelligence. Web 3.0 introduces the concept of semantic web. According to the World Wide Web Consortium, “The Semantic Web provides a common framework that allows data to be shared and reused across application, enterprise, and community boundaries.” Computers record what humans are doing.  

The evolution of internet is a continuous process. Web 1.0, Web 2.0, now Web 3.0 and it will continue changing. All these changes have given the power to the consumer to redirect the emergence of new ways of communication. It started with the need of having access to information. However, it evolved very fast as a way of interaction and the future is known.
