The invention relates to a method and system to communicate primary and secondary content streams to at least one remote unit, for example, via a television channel in a targeted television environment. The secondary content stream comprises a plurality of tertiary content streams (e.g., video streams) providing commercials, advertisements or any other content. The tertiary content streams are included in the secondary content stream as a mosaic so that each tertiary content stream is a subset or portion of an active display area or frame provided by the single secondary content stream. In one exemplary embodiment, the method and system provide targeted or specific commercial advertisements to demographically selected audiences.
