00:00:00,120 --> 00:00:01,920
Speaker 1: This Day in History Class is a production of I

2
00:00:02,040 --> 00:00:06,720
Speaker 1: Heart Radio. Hey y'all, I'm Eves and welcome to This

3
00:00:06,800 --> 00:00:09,959
Speaker 1: Day in History Class, where we uncover a new layer

4
00:00:10,039 --> 00:00:23,960
Speaker 1: of history every day. Today is November two. The day

5
00:00:24,079 --> 00:00:29,120
Speaker 1: was November two, nineteen thirty six. The British Broadcasting Corporation

6
00:00:29,240 --> 00:00:33,600
Speaker 1: or BBC television service was broadcast from Alexandra Palace in

7
00:00:33,680 --> 00:00:37,800
Speaker 1: North London, making it the world's first regularly scheduled public

8
00:00:37,880 --> 00:00:42,919
Speaker 1: high definition television service. The BBC had been experimenting with

9
00:00:43,040 --> 00:00:48,200
Speaker 1: television broadcasts since the late nineteen twenties. Scottish engineer John

10
00:00:48,280 --> 00:00:52,320
Speaker 1: Logie Baird, who demonstrated the first working television in ninety

11
00:00:52,720 --> 00:00:56,240
Speaker 1: and succeeded in transmitting live pictures from London to New York,

12
00:00:56,720 --> 00:01:01,560
Speaker 1: helped set up the BBC's first television program. Baird built

13
00:01:01,560 --> 00:01:05,839
Speaker 1: a television studio in long Acre, experimenting with a small transmitter.

14
00:01:06,840 --> 00:01:10,080
Speaker 1: He used his electro mechanical system with a vertically scanned

15
00:01:10,120 --> 00:01:14,400
Speaker 1: image of thirty lines. But TV needs one transmitter for

16
00:01:14,520 --> 00:01:17,840
Speaker 1: sound and one for picture. Because the BBC only had

17
00:01:17,920 --> 00:01:21,240
Speaker 1: one transmitter, the first TV programs had to have a

18
00:01:21,280 --> 00:01:24,039
Speaker 1: couple of minutes of picture followed by a couple of

19
00:01:24,080 --> 00:01:28,160
Speaker 1: minutes of sound. By March of nineteen thirty the BBC

20
00:01:28,360 --> 00:01:32,000
Speaker 1: had a new twin transmitter and simultaneous sound and picture

21
00:01:32,040 --> 00:01:37,679
Speaker 1: transmission began. The BBC began broadcasting its first regular experimental

22
00:01:37,720 --> 00:01:42,520
Speaker 1: television programming on August two, two from Studio BB in

23
00:01:42,560 --> 00:01:47,000
Speaker 1: the basement of Broadcasting House, its headquarters in London. The

24
00:01:47,000 --> 00:01:50,160
Speaker 1: initial broadcast were produced by Eustace rob and the chief

25
00:01:50,200 --> 00:01:54,800
Speaker 1: engineer was Douglas Berkenshaw. Baird appeared on the first program

26
00:01:54,840 --> 00:01:59,320
Speaker 1: to thank the BBC. The BBC's early TV programs demonstrated

27
00:01:59,360 --> 00:02:03,880
Speaker 1: the potential the medium. These regular daily transmissions continued until

28
00:02:03,920 --> 00:02:07,200
Speaker 1: the system shut down in to make way for the

29
00:02:07,240 --> 00:02:11,440
Speaker 1: new high definition service. A German TV service had begun

30
00:02:11,480 --> 00:02:15,000
Speaker 1: in nineteen thirty five, but since it only offered pictures

31
00:02:15,000 --> 00:02:17,840
Speaker 1: with one hundred and eighty lines, it did not qualify

32
00:02:17,919 --> 00:02:21,760
Speaker 1: as high definition in the BBC's book. The BBC had

33
00:02:21,800 --> 00:02:24,560
Speaker 1: decided that anything two hundred and forty lines or above

34
00:02:24,760 --> 00:02:29,000
Speaker 1: was high definition. After tests and special broadcast began in

35
00:02:29,000 --> 00:02:32,920
Speaker 1: August of nineteen thirty six, the BBC Television service officially

36
00:02:33,040 --> 00:02:36,200
Speaker 1: launched under the leadership of Director of Television Gerald Cox.

37
00:02:36,360 --> 00:02:40,640
Speaker 1: On November second ninety six. The first program was a

38
00:02:40,639 --> 00:02:45,160
Speaker 1: bulletin of British movie Tone News. The Television Advisory Committee

39
00:02:45,160 --> 00:02:47,919
Speaker 1: recommended that both the Beared two hundred and forty line

40
00:02:47,919 --> 00:02:51,239
Speaker 1: mechanical system and the Marconi e m I four hundred

41
00:02:51,280 --> 00:02:54,200
Speaker 1: and five line electronic system be used for the new

42
00:02:54,240 --> 00:02:59,880
Speaker 1: television station. Each system had its own broadcast studio. Early

43
00:03:00,000 --> 00:03:03,880
Speaker 1: television sets supported both systems, and the BBC transmitted them

44
00:03:03,880 --> 00:03:08,120
Speaker 1: on alternating weeks during a trial period. An estimated five

45
00:03:08,560 --> 00:03:13,520
Speaker 1: television sets received the BBC Television Services broadcast. The initial

46
00:03:13,560 --> 00:03:16,720
Speaker 1: broadcast only ran from three to four pm and nine

47
00:03:16,760 --> 00:03:20,760
Speaker 1: to ten pm Monday to Friday. The Marconi system one

48
00:03:20,800 --> 00:03:23,840
Speaker 1: out in nineteen thirty seven after the Beared system was

49
00:03:23,880 --> 00:03:28,320
Speaker 1: deemed too cumbersome and its visual quality proved inferior. The

50
00:03:28,360 --> 00:03:32,320
Speaker 1: BBC did its first major television outside broadcast in May

51
00:03:32,360 --> 00:03:35,080
Speaker 1: of nineteen thirty seven, when it took cameras to the

52
00:03:35,120 --> 00:03:39,440
Speaker 1: coronation of King George the six. Because recording technology was

53
00:03:39,480 --> 00:03:43,560
Speaker 1: not yet available, people used a technique called telerecording, also

54
00:03:43,640 --> 00:03:46,840
Speaker 1: known as kinescoping, where a camera focused on a television

55
00:03:46,880 --> 00:03:50,960
Speaker 1: screen filmed the live picture to preserve the broadcast. A

56
00:03:51,000 --> 00:03:54,240
Speaker 1: Marconi Company employee filmed the coronation on his home TV.

57
00:03:55,520 --> 00:03:58,040
Speaker 1: The last program to air before World War Two brought

58
00:03:58,080 --> 00:04:01,880
Speaker 1: broadcast to a halt was a Mickey Mouse cartoon. The

59
00:04:01,920 --> 00:04:05,320
Speaker 1: station was taken off the air on September one, nine,

60
00:04:05,640 --> 00:04:08,440
Speaker 1: a couple of days before Britain declared war on Germany,

61
00:04:08,680 --> 00:04:11,360
Speaker 1: since Britain feared that the v h F four very

62
00:04:11,400 --> 00:04:15,200
Speaker 1: high frequency transmissions would act as a beacon to enemy aircraft.

63
00:04:15,920 --> 00:04:18,760
Speaker 1: There were an estimated twenty thous TV sets in Britain

64
00:04:18,800 --> 00:04:22,400
Speaker 1: at the time. BBC Television was back up and running

65
00:04:22,440 --> 00:04:25,960
Speaker 1: by June of ninety The Mickey Mouse cartoon that they

66
00:04:25,960 --> 00:04:30,080
Speaker 1: had left everybody with was shown twenty minutes after broadcasts resumed.
