I want to know the answer to the following question:
When did the BBC first change studios?
All the background I'm provided with is that "The studio moved to larger quarters in 16 Portland Place, London, in February 1934, and continued broadcasting the 30-line images, carried by telephone line to the medium wave transmitter at Brookmans Park, until 11 September 1935, by which time advances in all-electronic television systems made the electromechanical broadcasts obsolete.". Is that enough to answer the question?
