YouTube is an American video-sharing website headquartered in San Bruno, California. Three former PayPal employees—Chad Hurley, Steve Chen, Jawed Karim—created the service in February 2005. Google bought the site in November 2006 for US$1.65 billion. YouTube allows users to upload, rate, add to playlists, comment on videos, subscribe to other users, it offers a wide variety of corporate media videos. Available content includes video clips, TV show clips, music videos and documentary films, audio recordings, movie trailers, live streams, other content such as video blogging, short original videos, educational videos. Most of the content on YouTube is uploaded by individuals, but media corporations including CBS, the BBC, Hulu offer some of their material via YouTube as part of the YouTube partnership program. Unregistered users can only watch videos on the site, while registered users are permitted to upload an unlimited number of videos and add comments to videos. Videos deemed inappropriate are available only to registered users affirming themselves to be at least 18 years old.
YouTube and its creators earn advertising revenue from Google AdSense, a program which targets ads according to site content and audience. The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Music and YouTube Premium, subscription services offering premium and ad-free music streaming, ad-free access to all content, including exclusive content commissioned from notable personalities; as of February 2017, there were more than 400 hours of content uploaded to YouTube each minute, one billion hours of content being watched on YouTube every day. As of August 2018, the website is ranked as the second-most popular site in the world, according to Alexa Internet. YouTube has faced criticism over aspects of its operations, including its handling of copyrighted content contained within uploaded videos, its recommendation algorithms perpetuating videos that promote conspiracy theories and falsehoods, hosting videos ostensibly targeting children but containing violent and/or sexually suggestive content involving popular characters, videos of minors attracting pedophilic activities in their comment sections, fluctuating policies on the types of content, eligible to be monetized with advertising.
YouTube was founded by Chad Hurley, Steve Chen, Jawed Karim, who were all early employees of PayPal. Hurley had studied design at Indiana University of Pennsylvania, Chen and Karim studied computer science together at the University of Illinois at Urbana–Champaign. According to a story, repeated in the media and Chen developed the idea for YouTube during the early months of 2005, after they had experienced difficulty sharing videos, shot at a dinner party at Chen's apartment in San Francisco. Karim did not attend the party and denied that it had occurred, but Chen commented that the idea that YouTube was founded after a dinner party "was very strengthened by marketing ideas around creating a story, digestible". Karim said the inspiration for YouTube first came from Janet Jackson's role in the 2004 Super Bowl incident, when her breast was exposed during her performance, from the 2004 Indian Ocean tsunami. Karim could not find video clips of either event online, which led to the idea of a video sharing site.
Hurley and Chen said that the original idea for YouTube was a video version of an online dating service, had been influenced by the website Hot or Not. Difficulty in finding enough dating videos led to a change of plans, with the site's founders deciding to accept uploads of any type of video. YouTube began as a venture capital-funded technology startup from an $11.5 million investment by Sequoia Capital and an $8 million investment from Artis Capital Management between November 2005 and April 2006. YouTube's early headquarters were situated above a pizzeria and Japanese restaurant in San Mateo, California; the domain name www.youtube.com was activated on February 14, 2005, the website was developed over the subsequent months. The first YouTube video, titled Me at the zoo, shows co-founder Jawed Karim at the San Diego Zoo; the video was uploaded on April 23, 2005, can still be viewed on the site. YouTube offered the public a beta test of the site in May 2005; the first video to reach one million views was a Nike advertisement featuring Ronaldinho in November 2005.
Following a $3.5 million investment from Sequoia Capital in November, the site launched on December 15, 2005, by which time the site was receiving 8 million views a day. The site grew and, in July 2006, the company announced that more than 65,000 new videos were being uploaded every day, that the site was receiving 100 million video views per day. According to data published by market research company comScore, YouTube is the dominant provider of online video in the United States, with a market share of around 43% and more than 14 billion views of videos in May 2010. In May 2011, 48 hours of new videos were uploaded to the site every minute, which increased to 60 hours every minute in January 2012, 100 hours every minute in May 2013, 300 hours every minute in November 2014, 400 hours every minute in February 2017; as of January 2012, the site had 800 million unique users a month. It is estimated that in 2007 YouTube consumed as much bandwidth as the entire Internet in 2000. According to third-party web analytics providers and SimilarWeb, YouTube is the second-most visited website in the world, as of December 2016.
Segundo de Chomón
Segundo Víctor Aurelio Chomón y Ruiz was a pioneering Spanish film director and screenwriter. He produced many short films in France while working for Pathé Frères and has been compared to Georges Méliès, due to his frequent camera tricks and optical illusions, he is regarded as the most significant Spanish silent film director in an international context. Born in Aragon, Segundo de Chomón got into film through the efforts of his actress wife, Julienne Mathieu, who appeared in early Pathé Frères productions. Around 1900 he became an agent for Pathé Frères in Spain and distributing their films out of Barcelona. In 1901, De Chomón began producing actuality films in Spain on an independent basis and distributing them through Pathé. De Chomón specialized in producing stencil colored film prints and was one of the developers of the Pathéchrome process, patented by Pathé in 1905. Charles Pathé noted the quality of De Chomón's trick films and, from 1903, began to support these efforts with the desire of competing with Georges Méliès.
De Chomón was expert enough at making trick films and had proven himself so valuable to Pathé that in 1905 he and Mathieu moved from Barcelona to Paris, De Chomón was placed in charge of a color stencilling shop in addition to his periodic duties as a director. Through 1907, De Chomón worked in close collaboration with Ferdinand Zecca. Shortly afterward, Zecca moved into an executive position at Pathé and did little direction from that time. De Chomón worked with other directors. Although he remained with Pathé, in 1910 De Chomón returned to Barcelona and started an independent production company, Iberico Films, which proved short-lived. In 1912, De Chómon accepted an invitation to make films in Italy. In addition to his own films, he worked on special effects on the films of others, notably Giovanni Pastrone's epic Cabiria. Pastrone returned the favor in 1917 through collaborating on de Chomón's last directorial effort, La guerra e il sogno di Momi. After 1917, De Chomón principally worked on creating visual effects for the films of others, including Guido Brignone's Maciste in Hell and Abel Gance's Napoléon.
Towards the end of his life, de Chomón collaborated with Swiss inventor Ernest Zollinger to develop a photographic, two-color color film process. De Chomón was planning to get back into full-time film production on his own when he died of a heart attack at age 57; the year that de Chomón died, the Surrealists organized a soirée that would rehabilitate the artistic reputation of Georges Méliès and to begin the long process of recovering his films. De Chomón was forgotten in the wake of his death, though over time silent film collectors began to recognize some of his shorts and he was dubbed "The Spanish Méliès" in English-speaking lands. Two of his films, Le Spectre Rouge and El hotel Eléctrico, persistently circulated in the collector's market and were circulated by the Museum of Modern Art film library; the Italian film Cabiria featured what may have been the first "dolly shot" in the movies, utilizing a device built by de Chomón. Recognition came to de Chomón in his home country, as the Filmoteca de Catalunya established a special division with the purpose of collecting and cataloguing what was left of his output.
Many of de Chomon's Parisian Pathé Frères films have been recovered, but his Spanish and Italian productions have proven more elusive. Comparisons of de Chomón's work with that of Georges Méliès is inevitable, with those in De Chomón's court insisting that he was a better filmmaker, whereas those on Méliès' side insist that De Chomón was a mere imitator. While it is hard to top Méliès' achievements in discovering basic editing and in his eye-popping production designs, de Chomon was a more modern filmmaker than Méliès. De Chomón relied extensively on animation, a field in which he was a pioneer and a technique Georges Méliès if used. Moreover, de Chomón offered slight improvements on some techniques that Méliès had tried, such as in Les Kiriki, acrobates japonais. De Chomón's work was more expansive in terms of genre than that of Méliès. Méliès began making actualities in 1896, but after discovering and developing the trick film and fantasy genres, he stayed put, it is for his trick films that de Chomón will be best remembered.
Film historian Tom Gunning has suggested that Luis Buñuel and/or Salvador Dalí were familiar with de Chomón's Superstition andalouse years before making their experiment
A silent film is a film with no synchronized recorded sound. In silent films for entertainment, the plot may be conveyed by the use of title cards, written indications of the plot and key dialogue lines; the idea of combining motion pictures with recorded sound is nearly as old as film itself, but because of the technical challenges involved, the introduction of synchronized dialogue became practical only in the late 1920s with the perfection of the Audion amplifier tube and the advent of the Vitaphone system. During the silent-film era that existed from the mid-1890s to the late 1920s, a pianist, theater organist—or in large cities, a small orchestra—would play music to accompany the films. Pianists and organists would play either from improvisation; the term silent film is a retronym—a term created to retroactively distinguish something. Early sound films, starting with The Jazz Singer in 1927, were variously referred to as the "talkies," "sound films," or "talking pictures." Within a decade, the widespread production of silent films for popular entertainment had ceased, the industry had moved into the sound era, in which movies were accompanied by synchronized sound recordings of spoken dialogue and sound effects.
Most early motion pictures are considered lost because the nitrate film used in that era was unstable and flammable. Additionally, many films were deliberately destroyed because they had little value in the era before home video, it has been claimed that around 75 percent of silent films have been lost, though these estimates may be inaccurate due to a lack of numerical data. The earliest precursors to film began with image projection through the use of a device known as the magic lantern, which utilized a glass lens, a shutter, a persistent light source to project images from glass slides onto a wall; these slides were hand-painted, after the advent of photography in the 19th century, still photographs were sometimes used. Thus the invention of a practical photography apparatus preceded cinema by only fifty years; the next significant step toward the invention of cinema was the development of an understanding of image movement. Simulations of movement date as far back as to 1828—only four years after Paul Roget discovered the phenomenon he called "Persistence of Vision."
Roget showed that when a series of still images is shown at a considerable speed in front of a viewer's eye, the images merge into one registered image that appears to show movement. This is an optical illusion, since the image is not moving; this experience was further demonstrated through Roget's introduction of the thaumatrope, a device that spun at a high speed a disk with an image on its surface. The three features necessary for motion pictures to work were "a camera with sufficiently high shutter speed, a filmstrip capable of taking multiple exposures swiftly, means of projecting the developed images on a screen." The first projected proto-movie was made by Eadweard Muybridge between 1877 and 1880. Muybridge set up a row of cameras along a racetrack and timed image exposures to capture the many stages of a horse's gallop; the oldest surviving film was created by Louis Le Prince in 1888. It was a two-second film of people walking in "Oakwood streets" garden, titled Roundhay Garden Scene.
The development of American inventor Thomas Edison's Kinetograph, a photographic device that captured sequential images, his Kinetoscope, a device for viewing those images, allowed for the creation and exhibition of short films. Edison made a business of selling Kinetograph and Kinetoscope equipment, which laid the foundation for widespread film production. Due to Edison's lack of securing an international patent on his film inventions, similar devices were "invented" around the world. In France, for example and Louis Lumière created the Cinématographe, which proved to be a more portable and practical device than both of Edison's as it combined a camera, film processor, projector in one unit. In contrast to Edison's "peepshow"-style kinetoscope, which only one person could watch through a viewer, the cinematograph allowed simultaneous viewing by multiple people, their first film, Sortie de l'usine Lumière de Lyon, shot in 1894, is considered the first true motion picture. The invention of celluloid film, strong and flexible facilitated the making of motion pictures.
This film was 35 mm wide and was pulled using four sprocket holes, which became the industry standard. This doomed the cinematograph; the art of motion pictures grew into full maturity in the "silent era". The height of the silent era was a fruitful period, full of artistic innovation; the film movements of Classical Hollywood as well as French Impressionism, German Expressionism, Soviet Montage began in this period. Silent filmmakers pioneered the art form to the extent that every style and genre of film-making of the 20th and 21st centuries has its artistic roots in the silent era; the silent era was a pioneering one from a technical point of view. Three-point lighting, the close-up, long shot and continuity editing all became prevalent long before silent films were replaced by "talking pictures" or "talkies" in the late 1920s; some scholars claim that the artistic quality of cinema decreased for several years, during the early 1930s, until film directors and production staff adapted to the new "talkies" around the late 1930s.
Spain the Kingdom of Spain, is a country located in Europe. Its continental European territory is situated on the Iberian Peninsula, its territory includes two archipelagoes: the Canary Islands off the coast of Africa, the Balearic Islands in the Mediterranean Sea. The African enclaves of Ceuta, Peñón de Vélez de la Gomera make Spain the only European country to have a physical border with an African country. Several small islands in the Alboran Sea are part of Spanish territory; the country's mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar. With an area of 505,990 km2, Spain is the largest country in Southern Europe, the second largest country in Western Europe and the European Union, the fourth largest country in the European continent. By population, Spain is the fifth in the European Union. Spain's capital and largest city is Madrid. Modern humans first arrived in the Iberian Peninsula around 35,000 years ago. Iberian cultures along with ancient Phoenician, Greek and Carthaginian settlements developed on the peninsula until it came under Roman rule around 200 BCE, after which the region was named Hispania, based on the earlier Phoenician name Spn or Spania.
At the end of the Western Roman Empire the Germanic tribal confederations migrated from Central Europe, invaded the Iberian peninsula and established independent realms in its western provinces, including the Suebi and Vandals. The Visigoths would forcibly integrate all remaining independent territories in the peninsula, including Byzantine provinces, into the Kingdom of Toledo, which more or less unified politically and all the former Roman provinces or successor kingdoms of what was documented as Hispania. In the early eighth century the Visigothic Kingdom fell to the Moors of the Umayyad Islamic Caliphate, who arrived to rule most of the peninsula in the year 726, leaving only a handful of small Christian realms in the north and lasting up to seven centuries in the Kingdom of Granada; this led to many wars during a long reconquering period across the Iberian Peninsula, which led to the creation of the Kingdom of Leon, Kingdom of Castile, Kingdom of Aragon and Kingdom of Navarre as the main Christian kingdoms to face the invasion.
Following the Moorish conquest, Europeans began a gradual process of retaking the region known as the Reconquista, which by the late 15th century culminated in the emergence of Spain as a unified country under the Catholic Monarchs. Until Aragon had been an independent kingdom, which had expanded toward the eastern Mediterranean, incorporating Sicily and Naples, had competed with Genoa and Venice. In the early modern period, Spain became the world's first global empire and the most powerful country in the world, leaving a large cultural and linguistic legacy that includes more than 570 million Hispanophones, making Spanish the world's second-most spoken native language, after Mandarin Chinese. During the Golden Age there were many advancements in the arts, with world-famous painters such as Diego Velázquez; the most famous Spanish literary work, Don Quixote, was published during the Golden Age. Spain hosts the world's third-largest number of UNESCO World Heritage Sites. Spain is a secular parliamentary democracy and a parliamentary monarchy, with King Felipe VI as head of state.
It is a major developed country and a high income country, with the world's fourteenth largest economy by nominal GDP and sixteenth largest by purchasing power parity. It is a member of the United Nations, the European Union, the Eurozone, the Council of Europe, the Organization of Ibero-American States, the Union for the Mediterranean, the North Atlantic Treaty Organization, the Organisation for Economic Co-operation and Development, Organization for Security and Co-operation in Europe, the Schengen Area, the World Trade Organization and many other international organisations. While not an official member, Spain has a "Permanent Invitation" to the G20 summits, participating in every summit, which makes Spain a de facto member of the group; the origins of the Roman name Hispania, from which the modern name España was derived, are uncertain due to inadequate evidence, although it is documented that the Phoenicians and Carthaginians referred to the region as Spania, therefore the most accepted etymology is a Semitic-Phoenician one.
Down the centuries there have been a number of accounts and hypotheses: The Renaissance scholar Antonio de Nebrija proposed that the word Hispania evolved from the Iberian word Hispalis, meaning "city of the western world". Jesús Luis Cunchillos argues that the root of the term span is the Phoenician word spy, meaning "to forge metals". Therefore, i-spn-ya would mean "the land where metals are forged", it may be a derivation of the Phoenician I-Shpania, meaning "island of rabbits", "land of rabbits" or "edge", a reference to Spain's location at the end of the Mediterranean. The word in question means "Hyrax" due to Phoenicians confusing the two animals. Hispania may derive from the poetic use of the term Hesperia, reflecting the Greek perception of Italy as a "western land" or "land of the setting sun" (Hesperia
