Abstract: The system and a computer-implemented method annotate a multimedia object on a web page hosted on a publisher computer system. A web page that includes a multimedia object is rendered in a web browser of a client computer system. One or more layers, including a transparent layer, at least partially located over the multimedia object displayed on the web page are generated wherein the one or more layers are configured to facilitate the creation and display of annotation data for the multimedia object based on user interface events produced by a user of the client computer system. Annotation data for the multimedia object is received from the user. The annotation data is transmitted to an annotation server for storage. A visual indicator indicating that the annotation data is associated with the multimedia object is displayed, wherein the visual indicator is rendered in the one or more layers.
