Input: Question: For how many years did BBC Choice operate? Passage:The BBC has traditionally offered regional variations across many of its services. The Home Service and its successor Radio 4 provided regional variations until the early 1980s when Local Radio took over these responsibilities. BBC One and the BBC Television Service have provided variations in the English regions throughout most of their history, and continues to do so today (mainly News and current affairs programming). In Scotland, Wales and Northern Ireland, BBC One has to a large degree been operated as a separate television channel, rather than a variant on BBC One as broadcast in England. BBC Two has in the past broadcast variations within the English regions, though now only has variations for Wales and Northern Ireland (BBC Two has ended the channel's Scottish variation on 17 February 2019 to give way to its new BBC Scotland channel that would launch a week afterwards). BBC Choice also briefly had regional variations for these areas.
