today we are literally stepping into history. we are at alexandra palace and this place has seen it all. today we are literally stepping into history. we are at alexandra palace and this place has seen it all. that's the studio in there. 2022 marks 100 years of the bbc. goodness me.

what began with a single radio transmission has transformed into a global broadcaster. in that time, it has covered the biggest events of successive generations, working to inform, educate and entertain the nation. and throughout those hundred years, the bbc has been pushing the boundaries of broadcasting, embracing and sometimes even creating the latest technology. 100 years of broadcasting. it is amazing when you think of it. you don't look a day over 30. and this studio in alexandra palace has a very special place in bbc history. in 1936 the bbc television service was launched right here on this spot. performers and orchestra would have been here. and a huge camera here! singing. and what viewers saw was this. this is adele dixon performing with the bbc television orchestra.

she is singing a song called television which was written especially for the opening night of... television. it was broadcast to viewers across london and the home counties through the transmitter on alexandra palace, marking the beginning of what was then referred to as high definition television. yeah, don't laugh. before that, television was just an odd fuzzy experiment to small, selected audiences. and behind—the—scenes there was a bit of a battle going on. see, the bbc had actually opened up two studios at alexandra palace. this, studio b was a mechanical system which was made byjohn logie baird and it produced an image like this. meanwhile, in studio a, they were trailing an electrical system by emi and what they would do is they would alternate studios and systems on different days the quality

of the baird system. it had other advantages too. and if you are filming with the baird system you need quite a lot of make up too. well, this is how it was, playmates. black and white, you see? and a bit of blue down each side of the nose. very sexy. the emi system on the other hand could capture a well lit studio perfectly fine, so the winner really wasn't hard to choose. under the lid of the emitron was this, a cathode—ray tube which is basically an old tv working in reverse, capturing the pictures instead of showing them. it stayed in use without much change for many, many years. the coronation of king george vi was the first time the cameras were used outside and the broadcast was watched by about 50,000 viewers.

however, it was the coronation of his daughter that really brought television into our homes. 70 years later, many millions of us watched the queen's funeral on smart tvs, phones, laptops, or on huge screens around the country, demonstrating just how far technology has moved on. way before television came radio.

it was just to say hello, we are ok. just give a bit of home news, and that was it. during rehearsal, there was the most enormous air raid, and the producer asked if one of the kids could come up and sing a song orsay kids could come up and sing a song or say a piece of poetry. i got up on stage, and they put a box so i could reach the microphone. it was one of those big bbc microphones. petula clark there. while sitting of singing careers and directing the

second world war, the microphone was clearly doing something right operationally. ice clearly doing something right operationally.— clearly doing something right operationally. clearly doing something right oerationall . . ., , ., operationally. ice had been on the round operationally. ice had been on the ground making — operationally. ice had been on the ground making ribbon _ operationally. ice had been on the| ground making ribbon microphone. operationally. ice had been on the i ground making ribbon microphone. it was a little too expensive, so in true bbc form, they made their own. for less than 10% of what rta were charging. the taipei state in use by the bbc from 193a until 1959. that is a long time when technology was developing so rapidly. what about inside? . it is called ribbon microphone, because behind the perforated cover is exactly that. a ribbon of metal. with the help of one of the trustee bbc engineering manuals, we can see that the sound waves coming from either the front or the back, and hit the ribbon in the middle. so then, that it flexes and wiggles when the vibrations hit

it, just like your eardrum. the flexing moves the ribbon through a magnetic field, created by two magnets on either site. this generates a small voltage which is unique to the sound it is taken in. the microphone connected to studio equipment that amplifies it to a level you can hear. because the ribbon is a flat piece of metal, it can interpret vibrations from both sites. finally we want to hear more of how the microphone sounds. we can hear it in use by sirjohn snack, the bbc voice who made the first announcement of the d—day landings, and went on to become one of the first television news readers. he recorded with the microphone for this demo tape. this recorded with the microphone for this demo tape.— this demo tape. this speech is recorded from _ this demo tape. this speech is recorded from bbc— this demo tape. this speech is recorded from bbc marconi. recorded from bbc marconi microphone.

pips. they are called the pips and when you hear them, you will know it is something o'clock. i find them quite soothing. but have you ever wondered why they exist? ships. the pips tell ships what time it is and help them navigate. at the height of the british empire, britain had a lot more ships than anyone else anywhere in the world and their maps all needed to follow a strict format so they could figure out where they were. the centre of all british nautical charts was the greenwich meridian, 0 degrees, and each vessel also kept a fancy clock on board that told them local time at the meridian and helped them to calculate their position really precisely. but over long journeys, how could the captains keep those clocks accurate to the second? well, to bring in the new year

in 1923, the bbc ran an experiment to broadcast the midnight bongs of big ben on the radio. it was a bonging success and the following year the first fully accessible time signal, the greenwich time signal, started to be broadcast every hour and it hasn't stopped since. the pips, as they were known, were generated by a swinging pendulum fitted with electrical contacts. so now you could have accurate greenwich mean time literally anywhere that you had a radio. the pips have become legendary, a symbol of bbc radio, and who better to tell us about them than another legend of bbc radio, tony blackburn. archive: welcome along - to the tony blackburn show this morning for this tuesday the ninth of december. my thanks, as always tojohn dunn for swinging us up until the seven o'clock hour. the pips have always been

a favourite of mine since 1967 when ijoined the bbc and opened up radio 1. archive: good morning everyone, welcome to the exciting new- sound of radio 1. everybody else finds it a bit weird that i like them but i do. i love them. on my programmes, i used to promote them, particularly because it is slightly extended. they were very useful at one time. before we just used to have an ordinary watch that would lose a minute a day. i used to set my watch by the pips. nowadays with smart watches, you don't need it as much, but it is still very bbc, and i like it. i wouldn't like to see it disappear. i wouldn't like to see it disappear. the original clock that kept the time still sits in the museum at the royal observatory. in the �*60s, though, an atomic clock started doing thejob which stayed in use until the 1990s, when it

transmitted its last pips from the royal observatory. ever since then, the bbc has generated its own pips from its atomic clock buried deep inside broadcasting house which uses gps signals to stay synchronised. so the next time you hear these, you know that they come from this. pips. mark zuckerberg has unveiled better�*s new hest headset. priced at just under $1500, it's almost 1500 times the price of the current headset. the british artist damien hirst, has started burning some of his pictures, to test the value of physical paintings versus digital

part of the bbc�*s research and development project for storing your data yourself, so the idea was that the device would keep track of what you are listening to and watching, but that data was just yours, unless you chose for it not to be. it was inspired by a new vision that sir tim berners—lee has for the web, to rethink the ownership of our data. back in 2018, he told us about what he calls a mid—course correction for the internet, an idea called solid. imagine a world where before you use an app it says to you, where do you want to store this data? all across the data spectrum, you have complete control over your private and personal data, which is very exciting, an exciting vision, i think for those people who get an inkling of what it's going to be like. right now when we interact with companies over the internet, often without even thinking about it, we give them our data — lots of it.

every website, app or streaming platform gathers information on us, our name and age, what we like to share, our files, photos, in fact all of our online browsing habits. platforms use this data to create recommendations, improve algorithms, or sometimes just for the purpose of selling it. but tim berners—lee's idea turns this on its head, giving power back to the individual. with solid, as users travel across the internet, all their data is stored in something called a pod. this is an individual�*s databank in the cloud which only they, or those they give permission to, can see. so instead of the data freely flowing to companies when they want to access it, they have to ask for the user's permission. if this is approved they can look into the pod to view or add information. with pods, because you are in control, you can share what you have watched or listened to on one platform with the others, something

the companies would never want you to be doing, but it means you could get more personalised recommendations. and if you want to stop using a service, you can cut off access to your data. or you could, even more dramatically, delete the pod, destroy all the data, and remove all trace of anything you have ever done on the internet. yes, it is a big endeavour, but it is not a ridiculously huge endeavour. what is exciting right now is just at the point when we should be broadcasting this, we now have also a start—up, inrupt. four years on, it is a reality with bbc r&d working with inrupt to bring it to life. charlie, you have invited me to a party but it is no ordinary party. no, no, it's not. it is bbc together, it's a watch party, but the particular difference here is your data is being protected in a new way.

watch parties allow friends to stream the same content at the same time, and they have exploded in the last few years. something like a third of under 30s actually had a watch party in the last 12 months, and it is really growing. so we have kind of built on the bbc�*s watch party and added the data pod element to it. as users log in, behind—the—scenes the software creates a pod for each person. here we go. and when you stop watching, this bbc trial shows you what data has been collected. we couldn't do a watch party without storing some data about you. the difference here is we are storing that data away from us, in your pod that you control.

there is a project in flanders happening at the moment, where some of your educational qualifications are being put into apart. solid is just one of many ideas aiming to help us own our data. others, even allowing us to sell it, have failed to take off at scale — maybe the incentives haven't been right. but that could change. bbc r&d and tim berners—lee certainly think it might, and they have both been right before. and there you have it, 100 years of the bbc in 11 minutes. if you would like 100 years of the bbc in 23 minutes, thanks for watching. see you.

hello there. our weather story will improve as the weekend progresses, but so far we've seen some rain, some of it heavy. this has been the progress of the wet weather this morning. we have seen around a quarter of an inch of rain in parts of north—west england, and that wet weather will continue to drift its way steadily northwards. it will be replaced by some blustery showers for saturday. a much drier, quieter story for most of us on sunday. the morning rain confining itself to the northern isles by the end of the afternoon. sunny spells and blustery showers around an area of low pressure, driven in by strong south—westerly winds. we'll see gusts in excess of 30 to 40 mph, maybe even stronger. the most frequent showers along exposed west facing coasts, perhaps the driest and brightest weather in sheltered eastern areas.

highs of 17 degrees here, a little cooler further north and west. this bodes well for the opening match of the rugby league world cup. yes, it is in newcastle. hopefully those showers will stay away this afternoon. as we go through the evening and overnight, the area of low pressure driving though showers will drift its way steadily northwards. it will allow a brief ridge of high pressure to build for a time, and that will quieten things down for sunday, before another weather front gradually pushes into the south—west. with those clearing skies, it will be a chilly start to sunday morning, with single figures here. still some showers lingering in the far north of scotland. we'll continue to see some showers north—west of the great glen throughout the day on sunday. for most of us, dry, settled with more sunshine coming through. you can see the next weather front waiting the wings and that will gradually introduce more cloud and outbreaks of showery rain into south—west england, wales and eventually northern ireland by

the end of the afternoon. with the sunshine comes a little more warmth. also we'll see lighter winds during the day on sunday. highs of 18 degrees. as we move out of sunday into monday, that frontal system is more of an overnight feature. it will push its way through quite quickly, again quite a windy spell of weather to go with it. once it clears away we'll see a quieter start to the new working week, before more wet weather threatens by thursday onwards. that's it. take care.

freddie. good afternoon. the new chancellorjeremy hunt today indicated major changes to liz truss' entire economic strategy. in a round of interviews, mr hunt said mistakes had been made by the government and warned of what he called "very difficult decisions" ahead.
