What is Web 2.0?
While the Internet was gaining popularity during the 1990s, one Web site, launched in 1995, offered something a little more than the basic. It was a company called Amazon.com—a huge, online bookseller. You could not only find and purchase books and read publisher reviews of them, but you could read comments, ratings, and reviews created by other readers and add your own. You could actually visit their site to have a conversation about books. Going to an online bookstore suddenly became a social event! Amazon.com, in a basic way, describes the start of Web 2.0. However, there's more to Web 2.0.
As defined by Solomon and Schrum (2007),
"Web 2.0 is an invented term, coined in 2004… It encompasses the growing collection of new and emerging Web-based tools. Many are similar in function to desktop applications, with people using their browsers for access rather than installing the software on computers. Many tools are free and available to all, a change from applications that are purchased or licensed annually. Others are social in nature and promote self-expression, such as the community networks, blogs, wikis, and photo and video sharing sites."
