 The decreasing costs of television production and improving technology also enabled the gradual development of even smaller regions.In 1991, BBC East Midlands was finally created in Nottingham, BBC London (separated from BBC South East) became a region in 2001 and BBC North was split into BBC Yorkshire and BBC Yorkshire and Lincolnshire in 2004 – with the new millennium seeing several BBC regions moving into new premises.In the East, South and South West regions, sub-regional opt-outs during local news programmes have also been created (similar to those on ITV regional news programmes), based respectively in Cambridge, Oxford and Jersey.
