00:00:02,040 --> 00:00:10,000
Speaker 1: Welcome to brain Stuff from how Stuff Works. Hey, brain stuff,

2
00:00:10,000 --> 00:00:13,320
Speaker 1: it's Christian Seger. When you see a movie in the theaters,

3
00:00:13,440 --> 00:00:16,560
Speaker 1: you expect certain things like a heck of a good time,

4
00:00:16,760 --> 00:00:19,720
Speaker 1: some amazing sound, and a story played out on a

5
00:00:19,800 --> 00:00:25,880
Speaker 1: gigantic screen. You also probably think about popcorn. But that's weird, right,

6
00:00:25,960 --> 00:00:29,720
Speaker 1: How of all the snacks on earth did popcorn become

7
00:00:29,760 --> 00:00:33,280
Speaker 1: the mainstay of movie theaters. Well, it starts with a

8
00:00:33,280 --> 00:00:36,599
Speaker 1: bit of history. See, popcorn had been around for ages,

9
00:00:36,760 --> 00:00:40,600
Speaker 1: and it was a popular snack at nineteenth century fairs

10
00:00:40,640 --> 00:00:45,080
Speaker 1: and carnivals, especially after the invention of the first steam

11
00:00:45,159 --> 00:00:51,720
Speaker 1: powered popcorn popper back in eighty five. People love the crunchy, salty,

12
00:00:51,800 --> 00:00:56,040
Speaker 1: inexpensive snack, and movie theaters hated it. During the era

13
00:00:56,120 --> 00:00:58,760
Speaker 1: of silent film, these companies followed many of the same

14
00:00:58,840 --> 00:01:01,560
Speaker 1: rules as traditional the eaters, and they did not want

15
00:01:01,600 --> 00:01:04,360
Speaker 1: to be associated with a loud food that could distract

16
00:01:04,400 --> 00:01:07,440
Speaker 1: from the show. Additionally, there was a little bit of

17
00:01:07,480 --> 00:01:11,679
Speaker 1: a class consideration here, since audiences had to read the

18
00:01:11,760 --> 00:01:15,080
Speaker 1: dialogue on the screen, they had to be literate a

19
00:01:15,280 --> 00:01:19,520
Speaker 1: k a. A better sort of people with superior education.

20
00:01:20,040 --> 00:01:23,600
Speaker 1: Allowing popcorn inside was in the opinion of these theater

21
00:01:23,680 --> 00:01:26,800
Speaker 1: owners kind of like throwing sawdust on the floor and

22
00:01:26,840 --> 00:01:30,840
Speaker 1: just saying, sure, just spit wherever you want. Talkies or

23
00:01:31,040 --> 00:01:35,560
Speaker 1: films with spoken dialogue emerged in nine and this brought

24
00:01:35,600 --> 00:01:39,720
Speaker 1: movie theaters to the common folk. Suddenly anyone could cough

25
00:01:39,800 --> 00:01:42,400
Speaker 1: up some change, grab a seat, and understand what was

26
00:01:42,440 --> 00:01:45,399
Speaker 1: going on. This was also the time of the Great Depression,

27
00:01:45,400 --> 00:01:49,680
Speaker 1: when Americans from coast to coast pined for cheap, escapist entertainment.

28
00:01:50,000 --> 00:01:53,320
Speaker 1: So the average Americans finally found the cinema, and they

29
00:01:53,360 --> 00:01:57,440
Speaker 1: brought their snack culture along, and the depression affected theaters

30
00:01:57,520 --> 00:02:01,040
Speaker 1: as well. Theaters with the best chances of surviving were

31
00:02:01,080 --> 00:02:04,760
Speaker 1: the ones that gave customers what they wanted. If they

32
00:02:04,840 --> 00:02:08,760
Speaker 1: wanted to eat popcorn while watching a film, well so

33
00:02:08,880 --> 00:02:13,200
Speaker 1: be it. At first, independent vendors sold popcorn outside the theater,

34
00:02:13,320 --> 00:02:17,200
Speaker 1: profiting from the casual passers by as well as future

35
00:02:17,240 --> 00:02:21,840
Speaker 1: movie patrons. Since corn kernels were dirt, cheap, popcorn became

36
00:02:21,960 --> 00:02:27,240
Speaker 1: even more popular and things escalated. Movie theaters allowed vendors

37
00:02:27,280 --> 00:02:29,639
Speaker 1: to sell popcorn in the lobby for a small fee.

38
00:02:29,840 --> 00:02:33,960
Speaker 1: Eventually they cut out the vendors entirely, acquiring their own poppers.

39
00:02:34,240 --> 00:02:37,840
Speaker 1: During World War Two, popcorn sales saw another bump. Sugar

40
00:02:37,919 --> 00:02:41,640
Speaker 1: was rationed, which made many conventional sweet snacks and drinks

41
00:02:42,040 --> 00:02:45,200
Speaker 1: more expensive, at least that is when they were available

42
00:02:45,200 --> 00:02:49,720
Speaker 1: at all. Popcorn, of course, only required salt and popcorn kernels,

43
00:02:49,800 --> 00:02:52,440
Speaker 1: neither of which were hard to come by. But by

44
00:02:52,520 --> 00:02:56,760
Speaker 1: then the association between movies and popcorn was firmly established

45
00:02:56,800 --> 00:02:59,960
Speaker 1: in the mind of the American public. This association can

46
00:03:00,040 --> 00:03:03,480
Speaker 1: and use today. But there's another wrinkle to the story.

47
00:03:03,880 --> 00:03:07,280
Speaker 1: And you might be saying, Christian, Okay, popcorn was cheap

48
00:03:07,320 --> 00:03:10,000
Speaker 1: in the depression or whatever, But what happened when did

49
00:03:10,040 --> 00:03:15,120
Speaker 1: it become so expensive? Good question. The price hike really

50
00:03:15,200 --> 00:03:18,960
Speaker 1: kicked in on all concessions back in the nineteen seventies.

51
00:03:19,120 --> 00:03:22,640
Speaker 1: See Contrary to popular belief, your local movie theater doesn't

52
00:03:22,680 --> 00:03:26,800
Speaker 1: actually make that much bank off the films it screens. Instead,

53
00:03:27,200 --> 00:03:30,600
Speaker 1: theaters use concessions to stay in business. According to the

54
00:03:30,639 --> 00:03:34,960
Speaker 1: Stanford Business School, concessions comprise only about of a theater's

55
00:03:34,960 --> 00:03:39,760
Speaker 1: gross revenue, but of its profits. This makes sense when

56
00:03:39,760 --> 00:03:43,960
Speaker 1: we consider how theaters must split ticket revenue with distributors,

57
00:03:44,080 --> 00:03:48,400
Speaker 1: but can pocket of whatever they managed to sell at

58
00:03:48,440 --> 00:03:52,160
Speaker 1: the snack counter. The bulk cost of the ingredients is

59
00:03:52,320 --> 00:03:57,040
Speaker 1: laughably small, and the profit margin is huge, and don't forget,

60
00:03:57,480 --> 00:04:05,800
Speaker 1: the stuff is still addictively delicious. Check out the brainstuff
