When where BBC studios built?

BBC StudiOS, as a concept, evolved over time, with the first BBC studio being established in 1923 at 200 Oxford Street, London. However, the current BBC StudiOS, which is a commercial subsidiary of the BBC, was formally created in 2017 to focus on production and distribution of content. Many of the prominent studiOS, like those at BBC Elstree and BBC Television Centre, were built in the mid-20th century and have since undergone various renovations and updates.
