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 as "prosumers" who both consume and create content. Examples of Web 2.0 include social media sites, blogs, wikis, video sharing sites, and web applications. Web 2.0 has given the public more access to media production tools and the ability to freely express themselves and share content online, competing with professional media. It has also increased user creativity and choice in how people access and engage with media.
