Marconi Round-Sykes magnetophone moving coil, 1923
Within six months of the start of broadcasting by the BBC, this new improved microphone was introduced. It was used for the famous 1924 outside broadcasts of the song of a nightingale singing along with cellist Beatrice Harrison in her garden in Oxted, Surrey.
Sound was picked up by a moving coil, positioned within a very powerful magnet. It was so sensitive that sounds such as buzzing insects were picked up for the first time.

Marconi-Reiss Marble Microphone, 1925
Reiss (Reisz), Marconi's Wireless Telegraph Co. Ltd.
This carbon microphone needed to be turned over daily to prevent the granules inside from settling. Although not nearly so sensitive as the earlier Round-Sykes microphone, it was far more widely used by the BBC because it did not require the same very high level of amplification

The Bomb Microphone, 1933
Standard Telephone and Cables Ltd.
This type of microphone was used to broadcast the abdication address of King Edward VIII over the BBC network from Windsor Castle on 10 December, 1936.
Its unusually-shaped aluminium housing contains a single-valve amplifier, which is needed because of the very weak signal produced by the microphone itself.
This microphone was very sensitive to humidity changes, and therefore never used for outside broadcasts.
Crystal Set Radio, 1922
Crystal set radios were relatively inexpensive to build, and did not require valves or batteries. The contact between a crystalline mineral and a spring of wire (known as a 'cat's whisker') was adjusted until a signal was received.
They were most listeners' first step into the world of radio, and a culture of home radio experimenting developed. Wives became 'wireless widows' as it was usually men who immersed themselves in this new hobby.
Lip Microphone, 1937
BBC, Marconi, Type L
This microphone was specially designed by the BBC to cancel out unwanted background noise during outside broadcasts. A metal guard ring at the front gives a precise speaking distance of 2.5 inches when pressed against the top lip. For this reason these microphones became known as Lip microphones.
The essential design has never been improved upon, and microphones like this are still in use today.
Big Ben Microphone, 1924
Standard Telephone and Cables Ltd.
To usher in 1924, Big Ben was broadcast for the first time. Later, microphones were permanently installed inside the clock tower and connected directly to Broadcasting House.
This moving coil microphone is one of a number that were used over the years. Its low sensitivity allowed it to be installed right by the bell, and cut out unwanted street noise.
Chakophone Radio, 1927
There is a switch on the front of the Chakophone radio to tune in to BBC broadcasts on medium wave, and an XX setting to receive long wave stations. It required external batteries for power, and could be listened to with headphones or a loud speaker.
As radio increased in popularity, sets became larger and more sophisticated - the more valves, the better. Deluxe models were given ornate traditional or modern wooden cabinetsm and floor-standing sets in particular began to take on the visual appearance of furniture.
Biscuit Tin Radio, 1943
British Government Miniature Communications Receiver, Mark 1 (MCR1)
During World War II, these compact radios were hidden inside biscuit tins and dropped by parachute. They were crucial to resistance fighters in Europe because the Germans had confiscated all normal civilian radios.
BBC London's public broadcasts were used to communicate with resistance groups by using obscure 'personal messages' which had secret meanings.
Marconi AXBT microphone, c.1944
Used by George Orwell, Winston Churchill, Charles De Gaulle, and others, the Type A is iconic, symbolising the early BBC.
The AXBT was the 4th generation design of the original Type A microphone (X, B and T representing improvements) widely used by the BBC from 1934 onwards.
EMI Emitron camera, 1936
Post-war television re-started with the pre-war studio equipment. Shortages of money and resources meant that this Emitron camera, supplied to the BBC in 1936 was still being used to make programmes well into the 1950s.
What's in the Collection and what era does it cover?
The Collection is a fascinating mixture of props, day-to-day artefacts from the life of the BBC, and lots of historic technology. The survival of these objects is largely down to the efforts of BBC staff with an eye on history and the future, those who saved things for posterity. The Collection encompasses objects from the earliest days of the BBC (1922) up to the present.
Why did we acquire it?
The acquisition of the BBC Collection represented an ideal opportunity to better document the history of Britain's largest broadcaster while enhancing our existing collections of television and radio equipment.
How many objects are there, and where will we store them?
The BBC Collection consists of 946 discrete objects. The vast majority are being stored at the Science Museum Group's main storage facility in Wroughton (near Swindon) while some of the objects are being stored here in Bradford. Objects currently in Bradford include the Blattnerphone (1930) designed by early British film maker Louis Blattner, which used 6mm steel tape to record sound; two original Emitron television cameras (1936), and the objects on display in Experience TV.
What will we do with the Collection?
A flavour of what has been acquired is on display in Experience TV. In the future, the Collection will augment or be the subject of exhibitions concerning broadcasting across the Science Museum Group and other museums.
About the BBC
The BBC was Britain's first official broadcaster, founded in 1922 by a private consortium of six radio manufacturers to stimulate the sales of radio sets. Five years later, John Reith's vision changed the BBC from the British Broadcasting Company into the British Broadcasting Corporation, with a royal charter that it is still governed by today and his famous public service vision - to "inform, educate and entertain". The first broadcast came from London on 14 November, and over the next few years, "listening-in" became a popular national pastime.
Today, the BBC is the largest broadcaster in the world, and a massive multi-media organisation. As well as having an enormous effect on British culture, it has been extremely influential on the international scale as well, acting as an exporter and ambassador of British culture.
