Cinema, Radio, and Television: Crash Course History of Science #29


With this telegraph, a device invented way
back in the mid-1800s, I can communicate with you, even if you’re hundreds of miles away.
I can update you on stock prices or the movements of enemy troops. Or who’s going to the next week on Ru Paul’s Drag Race! What’s harder to do is make you laugh, tell
you a long story, sing you this metal song I wrote, or show you this hilarious cat who’s
terrified of this little toy rabbit—it’s adorable, trust me! For that more emotional, audiovisual mode
of communication, let’s ditch the telegraph and leverage some basic scientific discoveries
about sound, light, and electricity made during the nineteenth century. *Hank sings the Crash Course theme* [Intro Music Plays] The telephone, invented in the 1860s and ‘70s,
took personal communication to the next level. Both Scottish–Canadian inventor Alexander
Graham Bell and American engineer Elisha Gray created working telephone systems in 1876,
and the priority dispute between them is fascinating. But the telephone didn’t lend itself to
popular entertainment. It was a one-on-one technology, not a way of communicating to
the masses. So it wasn’t until the invention of commercial
sound recorders and motion picture cameras, in the late 1800s, that you could consume
the same media as other people around the globe. And for those devices, we need to head back
to the Menlo Park laboratory of Thomas Edison. Who was, by the way, also working on the telephone! Edison developed the phonograph, which literally
means “sound writing,” in 1877, shortly before the lightbulb and electrical power
system that made him famous. Maybe Edison was interested in recording,
amplifying, and playing back sounds because he was hard of hearing. He might have imagined
alternative strategies for recording that hearing people wouldn’t have thought of. Edison’s team invented a recording cylinder,
which offered good sound quality. It worked by vibrating a thin membrane wrapped around
the cylinder, and then amplifying those vibrations, or making them louder. But other inventors created the commercially
popular record—a big, flag disc that stores audio information easily by using the ridges
of records to encode sound waves. Either way, phonographs are pretty simple
and durable—and still in use! All of you “long play”-collecting vinyl heads are
enjoying a fancier version of the phonograph every time you start your turntables. Edison’s cylinders were originally used
mostly for office dictation by big companies and had little impact on the consumer market. In fact, Edison invented a lot of stuff that
consumers would either ignore or outright despise. Probably the funniest example of an Edison-fail
was the talking doll, created in 1890. The doll had a recorder in its chest that could
play back “Mary Had a Little Lamb” and other kid-friendly hits. But the sounds grew faint quickly, making
an already creepy object that much creepier. Even Edison called the dolls his “little
monsters!” And Edison’s magnetic ore separator—which
was basically a big electromagnet that could pick up tiny bits of ore left behind by conventional
mining—straight-up bankrupted him! That said, this was actually a brilliant application
of the new science of electromagnetics. Just too far ahead of its time to work efficiently
in practice. Edison had better luck—post-doll, post-ore
separator—with moving pictures. As with his other inventions, he wasn’t
the first inventor, just the one who made a practical commercial system. Today, historians credit French artist Louis
Le Prince with the first workable movie camera. In 1888, he created the first known movie,
a very short one showing off Roundhay Garden in Leeds… it’s apparently a good garden… haven’t seen it myself. Then, Le Prince disappeared from a train and was never seen again, so… ThoughtBubble, show us how Edison made movie magic: As with the lightbulb, Edison didn’t do
the inventing himself, but relied on hiring creative experts. Still, he was the self-proclaimed
Napoleon of technology. So in the 1890s, Edison and Scottish inventor
William Dickson rolled out the Kinetograph, the first motion picture camera, which Dickson
invented at Menlo Park. Film movie cameras work by taking lots and
lots of photographs called frames. When they’re played back quickly, they give the illusion
of motion, because the human brain can only process so many images per second before it
just gives up. Edison also created the prototype for the
Kinetoscope, the first device for individual movie viewing, in 1891. He debuted this device
in Brooklyn in 1893. And in 1895, Edison created the Kinetophone, adding sound to his movies
via a cylinder phonograph. Edison’s early movies were not exactly Oscar-worthy,
although perhaps YouTube-worthy. They were only one minute long, and they often lacked
elements we associate with cinema today, such as plot. One of his early movies, for example, simply
depicted three of his blacksmiths, doing some smithing. Other memorable Edison productions
included “The Kiss,” “Fred Ott’s Sneeze,” Annie Oakley shooting glass balls, “Frankenstein,”
and everyone’s favorite, “Professor Welton’s Boxing Cats!” Most of these were shot in the first movie
studio, the Black Maria, which was created at Edison’s bigger, newer lab in West Orange,
New Jersey. One notable exception was “Electrocuting
an Elephant” which was filmed at Cony Island in which the aging elephant Topsy was killed using alternating current. It was sad and weird, and also popular. Thanks Thoughtbubble! Kinetoscope and Kinetophone movies took off
in saloons. And to Edison, this was enough. Movies didn’t need to be long or complex:
they’d never make any money that way! And besides, people have short attention spans. Other cinematic entrepreneurs had different
ideas. Unfortunately for them, Edison was an enormous patent troll! He had the patent
on the camera, so he kept suing other movie makers on the east coast. Which is one reason why they kept moving to
Los Angeles, the eventual epicenter of the movie industry. The other reasons were the
better natural lighting and weather, and the larger number of very good yoga studios-slash-juiceries. Dickson left Edison Studios to found Biograph
Pictures, and the French kept innovating. Brothers Auguste and Louis Lumière invented
the cinematograph in the 1890s with the idea of holding mass screenings. And, finally, in 1902, the U.S. Court of Appeals
ruled against Edison, finding that his company couldn’t hold the patent on all movie cameras,
just the specific model Dickson invented. But by then, cinema had moved to the west
coast, and the world would finally be able to bask in the glory of Point Break. Radio came decades after cinema. Which may
sound odd—it’s just sound, after all. But radio waves have to travel long distances
without losing fidelity, or accuracy. Whereas movies were carted around using physical reels
of film. Scottish physicist James Clerk Maxwell predicted
the existence of radio waves back in the 1860s. But German physicist Heinrich Hertz discovered
in 1885 that a wire carrying an electric current will radiate, or give off, electromagnetic
waves when it’s swung back and forth. That is, he made an antenna. Hertz researched the waves that antennae give
off, becoming the first person to show in an experiment how to make and detect electromagnetic
waves. His work led directly to radio. Today we measure the frequencies of electromagnetic
waves in units called hertz. Radio waves—the longest type of electromagnetic wave—are
measured in kilohertz, megahertz, or gigahertz. Inspired by Hertz’s research, a young Italian
inventor engineer named Guglielmo Marconi worked in the 1890s on how to send telegrams
wirelessly. Many people were interested in wireless communication,
but it was Marconi who first developed a working system. At home in Bologna, he sent and received
the first radio signals. Soon after, Marconi traveled to Britain to
commercialize his system. By 1899, he sent the first wireless telegraph signal across
the English Channel. And by 1901, he was able to send a single
letter, “S,” across the Atlantic Ocean, from England to Newfoundland, Canada. In this humble, sibilant way, radio was born!
And so Marconi won the Nobel in 1909. In fact, Nikola Tesla developed a working
radio system even before Marconi, but it was Marconi’s that took off commercially. That process took a long while. Regular radio
broadcasts began in 1920, in Pittsburgh, at the 100-watt station KDKA. And the British Broadcasting Corporation created
the first radio network in 1922. Radio broadcasts soared in popularity and became profitable
thanks to advertising. By 1936, three quarters of American households
owned a radio. Unlike a telephone, a radio worked without laying expensive copper wires. So this invention, and the automobile, connected
cities to rural areas and changed how people consumed music and sports. Radio also became a tool of political propaganda
and an indispensible way of communicating important news. The greatest example of this occurred on October
30, 1938, when Orson Welles directed an adaptation of H. G. Wells’s novel, “War of the Worlds,”
in which terrifying Martians invade earth and subdue humanity. Some people didn’t understand that this
was a drama – maybe they like, flipped on midway through, and mistook the realistic radio announcements for actual news, causing a panic. As radio was taking off, television was invented
and built on the infrastructure that supported it. And, like radio, TV would take a long time
to move from prototypes to commercial networks. Numerous people contributed to its development,
but one name stands out. Scottish engineer John Baird invented a mechanical TV in the
early 1920s. He used transparent rods to transmit images
of only thirty lines at at time, or pretty low resolution. Baird demonstrated the first televised images
in 1924, and moving ones in 1926. In 1928, he transmitted an image of a human face across
the the Atlantic Ocean. A year later, the BBC began broadcasting Baird’s
TV system. He even worked on color TV before 1930—a tech that wouldn’t become
standard until the 1950s. But in the end, the BBC switched to electronic,
rather than mechanical TV, adopting a system by Marconi’s company in 1936. Still, TV was expensive to produce, and receivers
were expensive. World War Two caused an intervening distraction, so television didn’t take off
as an industry until the 1940s. Telstar, the first satellite for global broadcast,
was launched in 1962. And then, on July 20, 1969, people all over
the world watched as a human set foot on the moon. We’ll get to space soon! Think of all of the communications technologies
required to enable almost everyone alive to watch the same Super Bowl, World Cup, or EuroVision
final! These technologies emerged from intensive,
competitive corporate research programs. Corporate invention at Menlo Park set the stage for
later R&D hubs at Standard Oil, General Electric, DuPont, Bell Labs, IBM Labs, and Google X. These places sought to, and seek to, turn
basic scientific discoveries about electromagnetism into patents and profits. Next time—we’re probing our own gray matter:
it’s the birth of psychology and psychiatry! Crash Course History of Science is filmed

  1. Just a note that we mention "Media" a lot in this video and we're talking specifically about Audio/Video Media. Obviously, print was a standard media at the birth of Radio and TV. 🙂

    – Nick J.

  2. The brother’s lumière’s dad invented the camera they used and they just used it for public screenings, which was pioneering at the time but u know… ☺️

  3. Hello CrashCourse, thanks for another great video! However, as far as I am aware, you're in error of when the film industry moved to California. The western film industry was not established in 1902 — Hollywood wasn't even incorporated until a year later. For shooting in warmer climates, the film industry first tried Jacksonville, Florida in 1908. For the next decade, the film industry centered around the northeast and Florida. I know that my home city, Ithaca New York, was a big silent film center as well. In the early 1910s, studios did begin to move to California and create the Hollywood we know today, becoming the dominant force by 1918. But as far as I am aware, the claim that the film industry was already in the west in 1902 is entirely incorrect.

    EDIT: I believe the issue is the appeal mentioned probably refers to the 1915 case against the Motion Picture Patent Company, a corporate trust set up to manage the film patents and was found violating the antitrust acts, thus freeing the film industry — but by this point, it was already a big force in the west, and still growing. This lines up a lot better with my previously mentioned dates, and follows the narrative set forth in this video. But I am still not sure where the date 1902 came from.

  4. 2:54 Oh, so THAT where the Mary doll urban legend come from: A talking doll talk through the telephone , saying her position to her victim until she’s right behind them and stabbed them death.

  5. learn from Tesla, even a true brilliant mind with fully working device still won't get you anywhere, but money, yes, a lot of money will….so don't be Tesla, …..be Edison, or in this era, be Elon Musk, how people praise Elon in this era, is how people praise Edison back then, is there Tesla of this era? well maybe, but if that's the case, then you don't know who the person is

  6. Ive always watched every crash course episode, unless ive mistakenly missed something.

    PLZ, make crash course MATH. Il go on repeat mode to stuff it in your subconcious

    CRASH COURSE MATH, CRASH COURSE MATH, CRASH COURSE MATH. Seriously though, everyone wants to see it.

  7. One very minor nitpick. In the name Newfoundland the accent is placed on "land", not reduced to "lind". I am from Newfoundland and we aren't mentioned abroad very often so when we are we'd like it to be said correctly. (Sadly there generally isn't a second mention for the correction to be broadcast.)

  8. So according to American people Edison invented cinema ? But why the hell was it invented by the Lumières brother in France? And those are no fake news there are museums and all you wish about them …

  9. Missed point: During WW2, the Beeb actually turned off its TV-transmitters, so even if you had a receiver there was literally nothing on TV

  10. Can you do a math video on like Percent of Change and adding tax to a total amount of money. Cuz my math teacher has explained it multiple times and I'm not getting it

  11. 9:20 I'm pretty sure there's limited if any evidence that people actually mistook the War of the Worlds broadcast as real.

  12. hey, here's another guy we don't like, let's make his every action seem evil… destroy his legacy, if he's still alive let's make sure he doesn't ever get a job and he starves to death. Average 16-39 year old – 2018

  13. I'm going to be a Scottish engineering and I'm glad so many Scottish engineers were show but as I was born in Wales could you show some people from there but none there is not a lot off people from there

  14. I'm somewhat disappointed that this episode focused so much on who invented what and when these technologies became wide-spread. I think it would be more interesting to also learn about the other factors making these developments possible. For example, these technologies require both highly theoretical knowledge and technical skill. Were the inventors well-verged in both or did they cooperate with artisans/engineers? What kind of changes in education and skill were required to actually create and operate these large infrastructures? And it is taken for granted that an innovation developed in Italy could simply be taken to England for commercialization and spread over the Atlantic. What kind of geopolitical environment made this possible? Why were states not trying to keep these technologies to themselves as a strategic advantage? I hope these kinds of factors, which seem more in line with earlier videos, get highlighted more in the future.

  15. Is it just me, or do others feel a great bit of sadness that CrashCourse gets a fraction of the views it used too. They put so much into each episode and I really hope it's sustainable.

  16. At least you weren't bowing to the shrine of Edison this episode. Still.. he should be a footnote, not a highlight. If Edison had any impact at all, it was in stifling and slowing the advance of technology.

  17. @CrashCourse You did not mention Antonio Meucci as the inventor of the telephone, even though the 2002-06-11 resolution of the US House of Representative accredited him (and not Bell) with the invention of such a device.

  18. Just 100 years ago, the world was so different. Science really is amazing. I can't wait to see what the future holds.

  19. "Brain just gives up" ~ The brain specifically interpolates between the images. It is doing what it evolved to do, for things like eye blinking.

  20. Jumping on the "outrage that you left out my personal favorite gypped historical figure" bandwagon — you highlighted Baird but not Philo T. Farnsworth?! That's like saying "Babbage deserves all credit for inventing the computer, all those electronics are just added polish. Who cares about Alan Turing or Tommy Flowers?"

  21. And you didn't mention David Snarnoff. Yeah, he wasn't a scientist or engineer, and he royally ripped off Farnsworth. But he was more critical to making TV what it is and what it means to society than anyone else in history.

  22. Disappointed with the discussion on the development of television. Focus should be on Zworykin and Farnsworth whose battle on the development of the electronic television was much more influential (and interesting) than the mechanical television. I may be biased though 😉

  23. “They all laughed at Christopher Columbus
    When he said the world was round
    They all laughed when Edison recorded sound
    They all laughed at Wilbur and his brother
    When they said that man could fly
    They told Marconi
    Wireless was a phony
    It's the same old cry”
    – Ira Gershwin

  24. Around 1910 Telefunken haad radio broadcasts from New York to Nauenberg, 3,850 miles. This is sure evidence the earth is in fact flat.

  25. What no women who you can laud for a minor contribution? – surely the (female) doll deserves much more prominence, as her involvement was clearly pivotal – her being female and all!

  26. Quite a commentary on the world in that I'm still not sure if the "Boxing Cats" movie is a joke or not 😛

  27. "Most of these were shot in the first movie studio, the Black Maria"

    For 15 years I've been wondering about the song Hang Em High by My Chemical Romance. It contains the lyrics "The angels just cut out her tongue. Call her Black Maria.Would I lie to you? That girl's not right in the brain." 

    I don't know if these two things are related, but that instantly made me think of that song.

    Addendum: After a brief wiki-wormhole, it turns out Black Maria is a slang term in ye-olden days for a police car. This fits with the time western time period of the song, and likely what it is referencing.

  28. The radio adaptation of War of the Worlds that caused panic was on a less popular radio station. The more popular radio station started playing an opera about a minute into the broadcast of War of the Worlds, causing people to change the station a minute into the broadcast, so they missed the intro that made it clear that it was fiction.

  29. The life blood that fueled the emerging corporations was simply the discovery made and the knowledge behind ELECTRODYNAMICS. Radio, Cinema and television came into being and there emergence provided information to all humans the world over…

  30. Cinema, Radio, Television, and other forms of entertainment before was merely created out of innovation of telecommunication. Thomas Edison is very smart and intelligent. He invented a lot of technology which we can use it until now. I loved how it give more viewed on the improvisation of communication through processing and how the technology invented.
    I'm very thankful as well as I'm proud for all the devices creation that oir scientists invented because it serve as our tool which make our life easier today.

  31. How talk about television without mentioning Philo Farnsworth known for inventing of the first fully electronic television?
    P.S. 3:45.. then he disappear from a train.. now visionaries are basement scientist with unimaginable technologies you'll never heard off.
