Companies and advertising agencies try to ensure consumers buy their products by understanding audience characteristics and targeting their advertising appropriately. They gather data on audiences through measurement panels, surveys, and research agencies to classify audiences based on demographics like age, socioeconomic status, and location. This information is used to highlight relevant product benefits, advantages over competitors, brand identity, and lifestyle appeal. Television advertising in the UK is regulated by organizations like Ofcom and the ASA to ensure advertising content and placement is appropriate.
