Disclosed is a method and system in which "labels," comprising supplemental information such as advertising, promotional, or informational elements including interactive elements, may be superimposed post-production into a video stream. This can be done by using overlay screens including interactive overlay screens or by combining video segments. As such, the labels do not have to physically be part of the actual scene during filming. Once a video stream is created, a space for available advertising is designated either manually or automatically by pattern recognition techniques. A list of available advertising space is generated. During viewing of television broadcasts, advertisements are placed in the video signal. Labels are displayed by superimposing an HTML page that is blank except for the advertisement onto the video signal. Advertisements can be superimposed post-production, and can be personalized and localized. The advertisements can be customized on a per-household basis.
