Abstract: A system for broadcasting inter-programme and/or intra-programme advertisements to a viewing or listening audience is disclosed. A given advertisement's target audience profile is matched to an obtained real audience profile to dictate not only that certain advertisements shall be broadcast only between and/or during certain programmes but also that certain individual members of, or groups of members within, the programme-receiving audience may receive one advertisement, during and/or between certain programmes, whilst other audience members or member groups receive a different advertisement, in one or more of the same respective advert ‘slots’, whilst watching or listening to the same broadcast.
