We all know what was the BBC Television Service and later BBC tv eventually became BBC One when BBC Two launched in 1964.
After the second World War when TV came back in 1946 (which legend (falsely) says started with "As I was saying before I was so rudely interrupted") the decision was taken to extend the medium to Birmingham by building the Sutton Coldfield transmitter in 1949/1950 and so on and so forth.
Was it planned from the start that BBC Television/tv/BBC One would have regional opts at Sutton Coldfield and future transmitters or was the regional opt thing added later, possibly in response to the (then) potential launch of what became ITV or even BBC Two?
There doesn't appear to have been any particular ordered roll out of BBC regional opts,
BBC Midlands started in 1964 ?
BBC South in 1961 (Three years after Southern TV opened, but I think around the time Day By Day launched?)
BBC South West 1961 (A week before Westward launched)
BBC Wales 1964 ? (About the time TWW took over TC's franchise ?)
Loads of gaps, but I'm sure others will fill in, and correct
