The result was the radical shakeup that took place following the publication of the "Broadcasting in the Seventies" report in 1969. The eastern part of the region was reborn as the Norwich-based BBC East, with both it and the smaller remaining BBC Midlands focussing entirely on regional television (primarily regional news) and local radio. Regional radio ceased almost entirely (save for regional opt-outs on Radio 4 until 1980), and all television and radio production for national networks was transferred to the separate BBC Birmingham network production centre.
