Hello and welcome to Broadcasting House. My name is John Escolme, the BBC's History Manager, and today I'm taking you on a tour of a very special building, Broadcasting House, the BBC's newest and the BBC's oldest building. Come along with me.

Well, here we are inside Cloze (1): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDE3JXUwMDIzJXUwMDA4 Broadcasting House in an area where we keep some of our treasures and one of the most historic items is an old Cloze (2): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDM1JXUwMDA0JXUwMDBhJXUwMDExJXUwMDFkJXUwMDFmJXUwMDE4JXUwMDA3JXUwMDAxJXUwMDBi . Well, these are three microphones, three very important microphones, and Cloze (3): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDM0JXUwMDBkJXUwMDEzJXUwMDE1JXUwMDAyJXUwMDE3 than today's microphones but very important because this is the first microphone that broadcast the voice of the monarch to the world in 1932 – King George the Fifth's words were first heard through these microphones.

So, now we're in Cloze (4): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDE2JXUwMDJiJXUwMDEy Broadcasting House and we're in one of the busiest places in the building – we're in the newsroom.  The newsroom is the largest in Europe, it's also Cloze (5): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDNhJXUwMDBiJXUwMDBlJXUwMDAwJXUwMDAyJXUwMDE3 than the old one because all the journalists are working together to share stories and it's busier because there's so much activity going on here. Let's move on.

So, this is one of the many Cloze (6): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDJhJXUwMDEzJXUwMDA1JXUwMDBkJXUwMDA2 studios you'd find in New Broadcasting House. As you can see, it contains all the latest technology so we can broadcast across the world – BBC World Service programmes – or programmes from BBC Learning Cloze (7): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDFkJXUwMDJiJXUwMDA5JXUwMDBiJXUwMDA1JXUwMDFhJXUwMDFi – and it's much smaller than an old radio studio. Years ago we'd be using big reels of tape to record just a few minutes of programmes.

Well, we've even more exciting things to show you, so come this way.

This, of course, is a Cloze (8): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDBjJXUwMDAy studio and here we have some of the TV Cloze (9): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDNiJXUwMDAyJXUwMDBjJXUwMDA4JXUwMDE3JXUwMDEzJXUwMDEy that we use for World Service television news bulletins, these are much Cloze (10): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDJiJXUwMDFlJXUwMDBjJXUwMDBkJXUwMDAwJXUwMDA5JXUwMDE3 than they used to be. In the 1950s and 60s they were much bigger. And here is where our newsreader would sit, put on his or her best smile and deliver the news, good or bad.

OK, we've got one more thing to show you, follow me.

Well, we're nearly out of time but before we go let me introduce you to one of the most famous things in this building. From the television programme Doctor Who, yes, it's a Cloze (11): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDFjJXUwMDI1JXUwMDBkJXUwMDA5JXUwMDBl !

Now, although we have a lot of famous people coming through this building, this Dalek gets more attention than anything else. The Dalek was designed in 1963 – this isn't an original – in fact this is the Cloze (12): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDJlJXUwMDEzJXUwMDE3JXUwMDAxJXUwMDFhJXUwMDA2JXUwMDAx for the 21st century in gleaming, glittering, gold fibreglass.

Well that's the end of the Cloze (13): camerasbiggerversionNewDalekTVtourlargerOldmicrophoneEnglishradiosmaller JXUwMDJjJXUwMDFiJXUwMDFhJXUwMDA3 . Thanks for joining me and I hope it's been as informative as you had hoped. Come again soon and bye for now.
