Hypermedia, an extension of hypertext, is a nonlinear medium of information that includes graphics, audio, video, plain text and hyperlinks. This designation contrasts with the broader term multimedia, which may include non-interactive linear presentations as well as hypermedia. The term was first used in a 1965 article written by Ted Nelson.Hypermedia is a type of multimedia that features interactive elements, such as hypertext, buttons, or interactive images and videos, allowing users to navigate and engage with content in a non-linear manner.
The World Wide Web is a classic example of hypermedia to access web content, whereas a conventional cinema presentation is an example of standard multimedia, due to its inherent linearity and lack of interactivity via hyperlinks.
