The structure of audio-visual television production in Andalusia is complex, particularly the composition of the business fabric of the television system in the autonomous community, insofar as it depends, to a large extent, on public television, Canal Sur Televisión. The aim of this study is to approach the reality of audio-visual production companies specialising in television to find out whether Andalusian public television is fulfilling its public service function and, above all, whether it is a matrix that generates the regional industrial and business fabric. The methodology is based on a simple structural approach, using professional empiricism and participant observation, where the techniques used were qualitative and quantitative: content analysis, direct observation and participant observation, bibliographic techniques, in-depth interviews (using the key informant tool) and surveys. All this took place during the years 2020, 2021 and 2022. The results point to the fulfilment of the obligation to promote the development of the Andalusian audio-visual fabric and that of audio-visual production companies, as observed in its regulations.
