full_context: Document 1: Television in Australia: The first television broadcast in Australia took place on 30 September 1929 at the Menzies Hotel in Melbourne, using the electro - mechanical Radiovision system.

Document 2: BBC Television: The two systems were to run on a trial basis for six months; early television sets supported both resolutions. However, the Baird system, which used a mechanical camera for filmed programming and Farnsworth image dissector cameras for live programming, proved too cumbersome and visually inferior, and ended with closedown (at 22:00) on Saturday 13 February 1937.
Document 3: BBC Television: The BBC began its own regular television programming from the basement of Broadcasting House, London, on 22 August 1932. The studio moved to larger quarters in 16 Portland Place, London, in February 1934, and continued broadcasting the 30-line images, carried by telephone line to the medium wave transmitter at Brookmans Park, until 11 September 1935, by which time advances in all-electronic television systems made the electromechanical broadcasts obsolete.
Document 4: Through the Dragon's Eye: Through the Dragon's Eye is an educational BBC Look and Read production, which was first aired on BBC Two from 19 September to 28 November 1989, and has been shown regularly ever since.

Document 6: Scene (British TV series): Scene is a British television anthology drama/documentary series made by the BBC for teenagers. Featuring plays on topical issues as well as documentaries, sometimes of a controversial nature, and by leading contemporary playwrights, programs were originally broadcast to a school audience as part of the BBC Schools strand. Dramas from the series were also regularly broadcast for a wider adult audience. The series ran episodically from 1968 to 2002 and some of the dramas went on to receive critical acclaim, nominations and awards including five in 1996–97 and a Prix Jeunesse in 1998 under series producer Andy Rowley (see below).
Document 7: How to Train Your Dragon: The first book in the series, following Hiccup as he captures a dragon as a rite of passage and attempts to train him so that he will not be exiled from Berk, as its tradition. Led by Gobber the Belch, Hiccup manages to catch a small dragon, whom he names Toothless, and attempts to train it through his own methods, when the How To Train Your Dragon book was found to have only one page and therefore unhelpful. During the final part of the rite of passage Toothless offends another dragon and a fight ensues between all the dragons. As this is seen as failure to train the dragons correctly, the boys are exiled, allowed to stay one night while a storm rages. During the storm, three Sea Dragons are washed up on the shore of the island and one seems a threat to the Vikings. Hiccup is chosen to negotiate with the dragon, who has eaten one of the other dragons. However, the dragon, who calls himself the Green Death, says he is going to kill all the Vikings. While the village elders argue over how to attack the Green Death, Hiccup, the boys and their dragons start a fight between the Green Death and the other sea dragon, the Purple Death, resulting in Hiccup nearly being swallowed and having to be rescued by Toothless, killing both sea dragons in the process. Hiccup and Toothless become heroes because of their bravery.
Document 8: BBC Television: Baird Television Ltd. made Britain's first television broadcast, on 30 September 1929 from its studio in Long Acre, London, via the BBC's London transmitter, using the electromechanical system pioneered by John Logie Baird. This system used a vertically-scanned image of 30 lines – just enough resolution for a close-up of one person, and with a bandwidth low enough to use existing radio transmitters. Simultaneous transmission of sound and picture was achieved on 30 March 1930, by using the BBC's new twin transmitter at Brookmans Park. By late 1930, 30 minutes of morning programmes were broadcast Monday to Friday, and 30 minutes at midnight on Tuesdays and Fridays, after BBC radio went off the air. Baird broadcasts via the BBC continued until June 1932.
Document 9: How to Train Your Dragon: The How to Train Your Dragon franchise from DreamWorks Animation consists of two feature films How to Train Your Dragon (2010) and How to Train Your Dragon 2 (2014), with a third feature film, How to Train Your Dragon: The Hidden World, set for a 2019 release. The franchise is loosely based on the British book series of the same name by Cressida Cowell. The franchise also consists of four short films: Legend of the Boneknapper Dragon (2010), Book of Dragons (2011), Gift of the Night Fury (2011) and Dawn of the Dragon Racers (2014). A television series following the events of the first film, Dragons: Riders of Berk, began airing on Cartoon Network in September 2012. Its second season was renamed Dragons: Defenders of Berk.

The second season of the show was added to Netflix in January 2016 and a third season in June 2016. A fourth season aired on Netflix in February 2017, a fifth season in August 2017, and a sixth and final season on February 16, 2018.
Document 10: BBC Television: After a series of test transmissions and special broadcasts that began in August 1936, the BBC Television Service officially launched on 2 November 1936 from a converted wing of Alexandra Palace in London. ``Ally Pally ''housed two studios, various scenery stores, make - up areas, dressing rooms, offices, and the transmitter itself, which then broadcast on the VHF band. BBC television initially used two systems on alternate weeks: the 240 - line Baird intermediate film system and the 405 - line Marconi - EMI system. The use of both formats made the BBC's service the world's first regular high - definition television service; it broadcast from Monday to Saturday between 15: 00 and 16: 00, and 21: 00 and 22: 00. The first programme broadcast -- and thus the first ever, on a dedicated TV channel -- was`` Opening of the BBC Television Service'' at 15: 00. The first major outside broadcast was the coronation of King George VI and Queen Elizabeth in May 1937.
Document 11: Dragontorc: Dragontorc is an action-adventure game developed by Steve Turner's Graftgold and released for the Amstrad CPC and ZX Spectrum by Hewson Consultants in 1985. It is a sequel to 1984's "Avalon The 3D Adventure Movie." The hero of "Avalon," Maroc the Mage, returns to defeat an evil witch and save Britain. The game was very well received by critics.
Document 12: BBC Television: After a series of test transmissions and special broadcasts that began in August, regular BBC television broadcasts officially resumed on 1 October 1936, from a converted wing of Alexandra Palace in London, which housed two studios, various scenery stores, make-up areas, dressing rooms, offices, and the transmitter itself, now broadcasting on the VHF band. BBC television initially used two systems, on alternate weeks: the 240-line Baird intermediate film system and the 405-line Marconi-EMI system, each making the BBC the world's first regular high-definition television service, broadcasting Monday to Saturday from 15:00 to 16:00 and 21:00 to 22:00.
Document 13: BBC Television: Mechanically scanned, 30-line television broadcasts by John Logie Baird began in 1929, using the BBC transmitter in London, and by 1930 a regular schedule of programmes was transmitted from the BBC antenna in Brookmans Park. Television production was switched from Baird's company to what is now known as BBC One on 2 August 1932, and continued until September 1935. Regularly scheduled electronically scanned television began from Alexandra Palace in London on 2 November 1936, to just a few hundred viewers in the immediate area. The first programme broadcast – and thus the first ever, on a dedicated TV channel – was "Opening of the BBC Television Service" at 15:00. The first major outside broadcast was the coronation of King George VI and Queen Elizabeth in May 1937. The service was reaching an estimated 25,000–40,000 homes before the outbreak of World War II which caused the service to be suspended in September 1939. The VHF broadcasts would have provided an ideal radio beacon for German bombers homing in on London, and the engineers and technicians of the service would be needed for the war effort, in particular the radar programme.

Document 15: Vision On: "Vision On" was conceived and developed by BBC producers Ursula Eason and Patrick Dowling to replace a monthly series "For Deaf Children" (1952–64), a programme paced slowly enough for children to read captions and subtitles. It was noted in surveys that a favourite for deaf children was "Top of the Pops", due to its lively and fast-moving format and that even the profoundly deaf could still enjoy the music's lower frequency notes.
