Abstract: A broadcast system is described for the distribution of audio and/or video data. A graphical user interface is provided, preferably via a dedicated website, on a network, for the selection of instances of the audio and/or video data. Upon selection of such data for play back, the data is streamed or otherwise transmitted to a user terminal and a charge is levied to the provider of the data. The instances of data are displayed on the graphical user interface by means of a menu window in which icons corresponding to the instances of data are caused to scroll. When a pointer device is moved over an icon, the icon is enlarged, and the scrolling of the list may be stopped.
