I was at a conference once, of public-sector arts worthies in Birmingham circa 2006, where a television expert on a panel mentioned the marked and measurable regional differences in taste in the UK. This was apparently directly measurable in things like viewing figures for the same programme in different places. The hostility to this idea from the arts people was palpable and vocal, both in terms of sharp comments and seat-stirrings/head-shakes. The idea seemed to me to present a challenge to their universalist understanding of culture. Now, the BBC is launching a new wave of specifically regional comedy.
