The present invention is directed to a full-page video interstitial advertisement. The interstitial advertisement offers advertisers a high quality, full screen video distribution opportunity for a set period of time, such as a 15 second spot, however the duration of the video may vary depending on the content of the video or the configuration of the webpage. A session manager controls the exposure of the interstitial advertisement to the user, to prevent the user from experiencing too frequent interstitial advertisements during a web session. The interstitial advertisement includes a fuse for displaying the playing progress of the video. The use of sound is preferred as part of the interstitial advertisement since it is important for the delivery of the media value of the advertisement. The interstitial advertisement spans the entire web browser screen, overlaid on top of the current web page using a transparency layer.
