Abstract: A computer customizes additional content provided with video advertisements in a video segment, by identifying a video advertisement included in a segment of video content streaming to a client device, determining a parameter of the client device or of a user of the client device, and selecting customized advertising content from multiple predetermined advertising choices, based on the parameter and on an identity of the video advertisement. An interactive ad object may be provided at a time determined by timing of the video ad in a streaming video session. The interactive ad object may include a link to additional information related to the video ad. The link may be customized for a particular client device and video session, for example by linking to the customized advertising content at a remote server.
