The 20th century witnessed a distinctive model of interlocking political, educational and artistic institutions, with the humanities at their core. Public bodies such as the British Academy and the BBC set the template for the optimistic, post-1945 era of public investment in the arts and humanities. The state actively supported their expansion after the war via such icons of mass cultural modernity as the Arts Council, BBC2, the Open University and the new redbrick universities. By the 1980s, this project had borne such fruits as the South Bank Show, the Birmingham School of Cultural Studies and Channel 4. Threaded through all of this was the principle that there was a public interest in understanding ideas, artefacts and events.
