The BBC has been creating and using indents for more than sixty years and many are known throughout the public and the media itself. As the years have gone by the indents have changed dramatically, from a plain black and white globe to a use of a variety of colours, for example, in one particular ident it contains hippos swimming in circles. This however, does represent the typical global features of the BBC due to the circle being used. With the imminent arrival of commercial television in Britain, the 2nd of December saw the arrival of the first ident in Britain, nicknamed the "Bat's Wings". On November the 15th 1969, BBC 1 began transmitting in colour, and introduced the first version of the "mirror globe" ident. By 1985 computer graphics technology had increased dramatically allowing for more expansive and visually pleasing indents.This in turn led to the ident containing a blue globe with the continents highlighted in gold to outline the success and level of the technology that the BBC now possessed. The BBC's virtual globe was introduced in 1991 and replaced the computer originated world. The world 'colour' identifying this new feature, was included in the station indents programming and producing. On 4th October 1997 the BBC globe was dramatically updated when it left the computer to take the form of a hot-air balloon filmed over various landmarks throughout the Uk, however, sometimes it is used flying over out of the UK locations, for example, flying over Sydney Harbour in the 200 olympic games. In 2002 the Balloon ident ( which turned out to be the shortest length of time an ident was used for) was banished from the BBC due to the changed in management/production. The new ident created was a routine of capoeira which is a South American type of dance/marital arts. This was part of he BBC's new 'rhythm and movement' ideas headed by the new management leader Lorraine Heggessey. In 2006, four years on from the 'Rhythm and Movement' ideas a new set of indents were introduced on October 7th and abandoned the 'overly red colour scheme' to give the company a new look. This relaunch also brought about a change in the BBC's logo. Finally due to the success of BBC One a nee channel named 'BBC Two' was introduced in 1964. It followed a basic ident pattern up until the 2000's with only a change in colour the real difference between its many indents. Since then, in 2007, the company had a relaunch inspiring a range of new indents costing £700,000. These indents contained the number two in a variety of backgrounds. The most stand out one of these is the number 2 cut in to a piece of wood, with the hole leading out in to the sea ( as shown in the image used on this page). Later on, BBC 3 was formed and immediately contained bright new indents due to increased levels of technology and public want for these particular indents. This channel is not as well known as BBC One and Two yet still is successful and gains even more wanted publicity for the BBC as a whole company. This channel has now been running for 11 years and continues to be a hit with the public. The story of BBC Television -
How it all began 'Television? The word is half Greek and half Latin. No good will come of it.' C.P. Scott, Editor, Manchester Guardian Television had long been a dream of inventors; serious attempts to build a television system started over 100 years before even the name was invented. Up to the 1920s, television was still called by a variety of names including: Radiovision, Seeing by Wireless, Distant Electric Vision, Phototelegraphy, The Electric Telescope, Visual Listening, Telectroscopy, Hear-Seeing, Telephonoscope, Audiovision, Radio Movies, The Radio Kinema, Radioscope, Lustreer, Farscope, Optiphone, Mirascope. Karl Braun By the time modern television became a reality, in the mid 1930s, there had already been over 50 serious proposals for television. The competition was truly international, with inventors and companies working in 11 different countries. Many of these pioneers had no success; a few however were able to produce silhouette pictures and were hailed as the 'inventors' of television within their own countries. Thus, the French say both Belin and Barthelemy were the inventors of television; the Japanese believe it was Takayanagi; the Russians say Boris Rosing; the Germans either Nipkow or Karolus; the Hungarians von Mihaly; in the USA most people believe it was either Jenkins or Farnsworth; and in the UK we have the choice of Campbell-Swinton for the concept, or John Logie Baird for television's practical demonstration. Although several pioneers had been working on the invention of television as far back as the 1850s, there were four key technologies that had to be developed before any form of television could become a possibility. These were:
Once all of these inventions were in place, they would still need further development before a successful television system could be invented. Paul Nipkow The first of the four key inventions happened in 1873 when a telegraph operator discovered that light affected the electrical resistance of selenium. It was soon realised that it was possible to change light into electricity using a selenium photocell. The next key invention came in 1884 when Paul Nipkow in Germany invented a disc with a single spiral of holes in it as a method of mechanical scanning for television. Although he was never able to build a working system, the Nipkow disc was later used by several TV pioneers as the basis for their own television systems. What was needed now was some device to turn an electric current back into light. A conventional light bulb was unsuitable because it could not vary its brightness fast enough to produce a TV image. The Neon lamp was developed by Georges Claude in France in 1902 and was used by many early television pioneers. However, the most important breakthrough had happened earlier (in 1897) when Karl Braun in Germany invented the cathode-ray tube. The 'Braun tube', although unusable for television at the time, would become the most important television display device for the next century. Lee DeForest The last invention in the chain came in 1906 when Lee de Forest in the USA invented the Amplion (amplifying triode valve), making it possible to amplify the weak video signals created by selenium photocells. A working amplifier took him another six years to develop, and nearly ten years would pass before this amplifier was improved enough for television. So by 1922 all the key elements were in place for the invention of television, and inventors around the world sensed that success was within reach. Many of them had well equipped laboratories and sufficient funds for staff and equipment. It is therefore surprising that success was snatched by a most unlikely figure.
