Abstract: An advertisement delivery technology for advertisers to place advertisements within a frame that wraps around media players embedded in web pages (the media player skin) is disclosed. Advertisers develop advertisements suited to be served into media player skin and avail the advertisements on an online advertisement platform. Video publishers integrate the advertisement delivery technology into their web pages to create media player skins that wrap around embedded video players. When a viewer visits one of these web pages to watch a video clip, the video player is loaded to play the video clip. The media player skin communicates with the online advertisement platform to retrieve an advertisement and places it within the skin. The viewer is exposed to the advertisement while watching the video clip.
