What is World Wide Web or Web

The 21st century has evolved when it comes to the presence of technology. Internet development has entailed a revolution in human life, especially in the field of interaction. The world has moved from the first Web 1.0 to Web 5.0, which not only allows users to access information but also to interact with millions of other users from every part of the planet. This global connection has led to the increasing necessity of being communicatively and interculturally competent. In this context, European countries develop bilingual education programs based on CLIL, whose main objective is to promote proficiency in non-linguistic and linguistic subjects and foster plurilingualism and intercultural awareness among citizens. Bearing in mind the social and educational implications of the increasing power of technology and the Internet, this chapter revises the progressive transformation of the World Wide Web from a social perspective since its origins until today, and it explains why integrating social media tools in the CLIL classroom could serve as a way to improve the results of bilingual programs.
