Web 2.0 is a term used to describe a second generation of the World Wide Web that emphasizes user-generated content, usability, and interoperability. It allows users to interact and collaborate online by contributing user-created content through social media and virtual communities. Examples of Web 2.0 include social networking sites, blogs, wikis, video sharing sites, and web applications. David Gauntlett suggests that Web 2.0 has impacted access, ownership, power, and creativity by making media production equipment more accessible, giving audiences more control over what and when they consume media, and allowing ordinary people to produce and distribute content and have their voices heard.
