In the case of linear multimedia, the end-user cannot control the content of the application. User is a observer of information. A linear multimedia application lacks all the features with the help of which, a user can interact with the application such as the ability to choose different options, click on icons, control the flow of the media, or change the pace at which the media is displayed.
