Web 2.0, also known as participative(or participatory) web or social web, refers to websites that emphasize user-generated content, ease of use, participatory culture, and interoperability (i.e.,compatibility with other products, systems, and devices) for end-users.
The term was coined by Darcy DiNucci in 1999 and later popularized by Tim O'Reilly and Dale Dougherty at the first Web 2.0 Conference in late 2004. Although the term mimics the numbering of software versions, it does not denote a formal change like the World Wide Web, but merely describes a general change that occurred during this period as interactive websites proliferated and came to overshadow the older, more static websites of the original Web.
A Web 2.0 website allows users to interact and collaborate with each other through social media dialogue as creators of user-generated content in a virtual community. This contrasts with the first generation of Web 1.0-era websites where people were limited to viewing the content in a passive manner. Examples of Web 2.0 features include social networking sites or social media sites (e.g., Facebook, Instagram, Tik Tok, etc.), blogs, and wikis, video sharing sites (e.g., YouTube), image sharing sites (e.g., Unsplash, Pixabay ), hosted services, Web applications ("apps"), collaborative consumption platforms, and mashup applications.
Characteristics of Web 2.0
Instead of merely reading a Web 2.0 site, a user can contribute to the site's content by commenting on published articles or creating a user account or profile, which may increase participation. By emphasizing these already-extant capabilities, they encourage users to rely more on their browser for user interface, application software ("apps"), and file storage facilities. This has been called "network as platform" computing. Significant features of Web 2.0 include social networking websites, self-publishing platforms (e.g., WordPress' easy-to-use blog and website creation tools), "tagging" (which enables users to label websites, videos or photos in some fashion), "like" buttons (which will allow a user to indicate that they are pleased by online content), and social bookmarking.

Users can provide the data and exercise some control over what they share on a Web 2.0 site. These sites may have an "architecture of participation" that encourages users to add value to the application as they use it. Users can add value in many ways, such as uploading their content on blogs, consumer-evaluation platforms (e.g., Amazon and eBay), news websites (e.g., responding in the comment section), social networking services, media-sharing websites (e.g., YouTube and Instagram) and collaborative-writing projects. Some scholars argue that cloud computing is an example of Web 2.0 because it simply implies computing on the Internet.
According to Best, Web 2.0's characteristics are rich user experience, user participation, dynamic content, metadata, Web standards, and scalability. Further characteristics, such as openness, freedom, and collective intelligence through user participation, can also be viewed as essential attributes of Web 2.0. Some websites require users to contribute user-generated content to have access to the website to discourage "free riding."
The key features of Web 2.0 include:
- Folksonomy – free classification of information; allows users to collectively classify and find information (e.g., "tagging" of websites, images, videos, or links)
- Rich user experience – dynamic content that is responsive to user input (e.g., a user can "click" on an image to enlarge it or find out more information)
- User participation – information flows two ways between the site owner and site users through evaluation, review, and online commenting. Site users also typically create user-generated content for others to see (e.g., Wikipedia, an online encyclopedia that anyone can write articles for or edit)
- Software as a service (SaaS) – Web 2.0 sites developed APIs to allow automated usage, such as by a Web "app" (software application) or a mashup
- Mass participation – near-universal web access leads to differentiation of concerns from the traditional Internet user base (who tended to be hackers and computer hobbyists) to a broader variety of users.
Social Media
A Web 2.0 website allows users to interact and collaborate through social media dialogue as creators of user-generated content in a virtual community. This contrasts with the first generation of Web 1.0-era websites, where people were limited to passively viewing the content. Examples of Web 2.0 features include social networking sites or social media sites (e.g., Facebook, Instagram, TikTok, etc.), blogs and wikis, video sharing sites (e.g., YouTube), image sharing sites (e.g., Unsplash, Pixabay ), hosted services, Web applications ("apps"), collaborative consumption platforms, and mashup applications.
