Web 2.0
The term Web 2.0 refers to websites that integrate user-generated content, place an emphasis on user experience, and offer improved interoperability.
Web 2.0 is the term that was coined out of a desire to differentiate between the simple static websites that first populated the web, and the web applications cropping up to take their place. Web 2.0 sites are marked by three primary characteristics that set them apart from their Web 1.0 predecessors:
- User-generated content: Whether in the form of blog comments, social media posts, product reviews, or wiki article submissions and editorial input, Web 2.0 sites enable website visitors to contribute to the content of the website.
- An emphasis on user experience: Features that are responsive to user input, such as a map web application that you can use to create personalized directions for a roadtrip, are a key component of Web 2.0.
- Improved interoperability: Web 2.0 websites began to incorporate application programming interfaces (API) to enable the use of website content in an external application or website, such as placing a social media feed in a website sidebar.
The term Web 2.0 was coined in 1999 by Darcy DiNucci. However, it didn't see widespread usage until 2004 when it was popularized at the O'Reilly Media Web 2.0 Conference.

Frequently Asked Questions
Does Web 2.0 refer to second version of the World Wide Web?
It's important to realize that the term Web 2.0 is not a reference to any formal technical update to the web. Web 2.0 does not refer to a new version of the World Wide Web, or to an update to any technical specification. As a matter of fact, Tim Berners-Lee, inventor of the web, has criticized the term Web 2.0 and called it nothing more than jargon.
According to Berners-Lee, his original vision of the web was “a collaborative medium, a place where we can all meet and read and write.” What other have termed as Web 1.0 and Web 2.0, Berners-Lee sees as the gradual growth in technology that has always supported this single central vision. While Web 2.0 does represent a change in how technology shapes the web, it does not reflect a departure from Berners-Lee's original vision of the web.
