Web 2.0 is the second wave of World Wide Web development, marked by the rise in social media and user-generated content, and the transition of web pages from static to dynamic. The term Web 2.0 does not denote upgraded content or improved technology, but rather a shift in the way the internet is now used. This shift is characterized by a new level of connectivity through social media and a surge of information sharing.
Web 2.0 refers to this version of the internet that is user-friendly and accessible 24/7. While previously, websites were available for viewing at any time, this version involves support, collaboration, discussions, and all possibilities for interaction 24/7. Web 2.0 technologies help corporations maintain connections with employees and between employees, encouraging participation and collaboration from any department, anywhere in the world. Connecting with customers has also never been easier, with improved, interactive communication options.
This shift signals the desire for "online communities" and the need for people to feel connected through the internet. Blogs, social networking, and web 2.0 applications all enable the public to become content creators and contribute thoughts, ideas, theories, and suggestions to the internet. While people were passive viewers of online content in the first iteration of the internet (Web 1.0), they are now active participants in what is seen and shared. Social media sites, blog sites, and Wikipedia are all examples of new Web 2.0 sites, encouraging users to create and publish their own content.
The next iteration of the World Wide Web will be Web 3.0, with many speculating that it will be referred to as the intelligent web or the semantic web. This semantic web is expected to be customized to each user, with greater intuitive technologies.
