The Culture, Welsh Language and Communications Committee held an inquiry into Film and Major Television Production in Wales, this is their report.
Since 1999 there has been large growth in the film and TV production sector in Wales, and across the UK as a whole. Growth has been significantly faster in Wales that it has across the UK as a whole. However, the sector in Wales still forms far less than a population-based share of the sector in the UK as a whole.
