Hypermedia means, an extension to hypertext providing multimedia facilities, such as those handling sound and vide. Hypermedia is a computer-based information retrieval system that enables a user to gain or provide access to texts, audio and video recordings, photographs and computer graphics related to a particular subject. Hypertext is text displayed on a computer or other electronic device with references or hyperlinks to other text that the reader can immediately access, usually by a mouse click or key-press sequence. Apart from running text, hypertext may contain tables, images and other presentational devices. This hypermedia is more or less an equivalent idea of multimedia content. Multimedia is media and content that uses a combination of different content forms. Multimedia includes a combination of text, audio, still images, animation, video, or interactivity content forms. Hypermedia may be broadly divided into linear and non-linear categories. Linear active content progresses without any navigational control for the viewer such as a cinema presentation. Non-linear user interactivity to control progress as used with a video game or used in self-paced computer based training. Hypermedia is an example of non-linear content. Multimedia presentations can be live or recorded.
Utility of Hypermedia
Hypermedia refers to “An extension to hypertext that supports linking graphics, sound, and video elements in addition to text elements’. The World Wide Web is a partial hypermedia system since is supports graphical hyperlinks and links to sound and video files. New hypermedia systems under development will allow objects in computer videos to be hyperlinked. In Education, multimedia is used to produce computer-based training courses (CBT) and reference books like encyclopedia and dictionaries. A CBT lets the user go through a series of presentations, text about a particular topic, and associated illustrations in various information formats.

Edutainment & Hypermedia
Edutainment is an informal term used to describe combining education with entertainment, especially multimedia entertainment. In mathematical and scientific research, multimedia is mainly used for modeling and simulation. In Medicine, doctors can get trained by looking at a virtual surgery or they can simulate how the human body is affected by diseases spread by viruses and bacteria and then develop techniques to prevent it. Document imaging is a technique that takes hard copy of an image/document and converts it into a digital format (for example, scanners). Ability Media allows those with disabilities to gain qualifications in the multimedia field so they can pursue careers that give them access to a wide array of powerful communication forms. In the Industrial sector, multimedia is used as a way to help present information to shareholders, superiors and coworkers. Multimedia is also helpful for providing employee training, advertising and selling products all over the world via virtually unlimited web-based technology. Software engineers may use multimedia in Computer Simulations for anything from entertainment to training such as military or industrial training. Multimedia for software interfaces are often done as collaboration between creative professionals and software engineers.
Newspaper companies all over are also trying to embrace the new phenomenon by implementing its practices in their work. While some have been already enter into the android markets through mobile phones viz., Tamil newspapers like Dina-thanthi, Dina-karan, Dina-malar and English newspapers like The Hindu, Indian Express, Chronicle, The Business Review are setting the precedent for the positioning of the newspaper industry in a globalized world.
Hypermedia may be developed a number of ways. Any programming tool can be used to write programs that link data from internal variables and nodes for external data files. Multimedia development software such as Adobe Flash, Adobe Director, Macromedia Author-ware, and Match-Ware Mediator may be used to create stand-alone hypermedia applications, with emphasis on entertainment content. Some database software such as Visual FoxPro and FileMaker Developer may be used to develop stand-alone hypermedia applications, with emphasis on educational and business content management.(Hicks David, 1998)
Adaptive hypermedia is a direction of research on the crossroads of hypertext (hypermedia) and user modelling. The goal of this research is to improve the usability of hypermedia. Adaptive hypermedia systems build a model of the goals, preferences and knowledge of the individual user and use this throughout the interaction for adaptation of the hypertext to the needs of that user. (Brusilovsky, 1998). We considered domain modeling and user modeling and showed methods and techniques for adaptation of hypertext, notably adaptive presentation and adaptive navigation support. Examples of adaptive hypermedia systems are described, including evaluations of the adaptation in those applications. Future developments include a generalization to adaptation in nodes other than text nodes and the creation of standards for adaptive hypermedia systems to communicate with each other and in order to exchange information on users between different applications. This can be applied and produced different models in future.
Parental role in multimedia
Internet has entered our personal, social, professional and educational environments; facilitating and improving the quality of our lives However, this multimedia technological “miracle” is accompanied with serious threats such as child sexual harassment, child pornography and exposure to inappropriate content and contact. Parents’ role is extremely important since children are extensively using the Internet. Parents’ awareness on Internet use and threats, can positively or negatively affect their children multimedia experience. Consequently, this research explores parent’s level of awareness in relation to their children internet usage and threats and whether they are interested to be further informed. Furthermore, it explores children’s motives in using internet, parents motives to provide internet to them and their interest on establishing a safe child web site to their household environment in order to control and monitor their children’s’ Internet usage.

Teaching through Transmedia
Transmedia teaching is a term that describes teaching and pedagogical techniques that work to create an immersive learning environment which extends beyond the limits of the classroom through the use of multiple, typically digital, media. Seven key characteristics of transmedia, or convergence, culture which center on how new and user generated digital media has come to transform the relationship between the original content provider and groups who were once imagined to be consumers of content. The emergence of a whole series of new media platforms and technologies (such as YouTube, blogging platforms, audio and video mash-ups, wikis and other collaborative environments of various descriptions, et c.) has encouraged both the “authorized” groups of content producers as well as groups of fans to create, manipulate, modify, and expand original content in ways that extended these franchises across a wide array of narratives and into different media environments.
