Why was BBC Scotland channel created in the first place? Was it pressure from Scottish Parliament to have the BBC provide a unique dedicated Scottish channel?
Government policies in a lot of areas (inc. Health, Education, Policing, Justice, Transport (most of it), Environment, Housing, Local Government, Farming, Forestry, Fisheries, Culture, Tourism and some taxation and benefits) are devolved and it used to annoy Scottish politicians (of all colours) very much that this distinction was often not made clear to viewers.
Network bulletins would talk about “the government” when referring to England & Wales only things, and maybe mention important initiatives seen as flagship up here later in their bulletins. This led to calls for a Scottish Six o’clock news on BBC One. This came up again and again over many years.
At one point, the Scottish Government even set up its own commission to investigate broadcasting in general to determine if there was any ‘unfairness’ going on in coverage.
In recent times, demands for a Scottish Six have rescinded and network bulletins are much, much better at explaining what policies apply where. Many people still felt/feel Scotland wasn’t getting the coverage it deserved from the BBC. That was in part where the whole new channel came from – although personally I think it is far more than anyone in public life was really asking for or expected.
The BBC still gets accused of all sorts of political bias here as it does elsewhere in the UK, but I don’t think they can be accused of not providing enough space for coverage of Scottish news and current affairs.
