Another move of recent years has been the regionalisation of BBC drama, in response to criticisms that the majority of programmes were made and set in and around London and the surrounding areas, with the BBC's central drama department currently being based at Television Centre in West London. As far back at 1962, the makers of "Z-Cars" had deliberately set their programme near Liverpool in the North of England to break away from the perceived London bias (although, ironically, it was shot in the BBC's London studios), and in 1971 an English Regions Drama Department had been established at BBC Birmingham headed by David Rose with a remit for making 'regional drama', gaining a major success with Alan Bleasdale's "Boys from the Blackstuff" in 1982. In the modern era, however, the separate BBC branches in Scotland, Wales and Northern Ireland all have their own drama departments with Heads of Drama who have autonomous commissioning powers, both for in-house production and co-production with or commissioning from independents.
