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.
In the music industry, a single is a type of release a song recording of fewer tracks than an LP record or an album. This can be released for sale to the public in a variety of different formats. In most cases, a single is a song, released separately from an album, although it also appears on an album; these are the songs from albums that are released separately for promotional uses such as digital download or commercial radio airplay and are expected to be the most popular. In other cases a recording released. Despite being referred to as a single, singles can include up to as many as three tracks; the biggest digital music distributor, iTunes Store, accepts as many as three tracks less than ten minutes each as a single, as does popular music player Spotify. Any more than three tracks on a musical release or thirty minutes in total running time is either an extended play or, if over six tracks long, an album; when mainstream music was purchased via vinyl records, singles would be released double-sided.
That is to say, they were released with an A-side and B-side, on which two singles would be released, one on each side. Moreover, only the most popular songs from a released album would be released as a single. In more contemporary forms of music consumption, artists release most, if not all, of the tracks on an album as singles; the basic specifications of the music single were set in the late 19th century, when the gramophone record began to supersede phonograph cylinders in commercially produced musical recordings. Gramophone discs were manufactured in several sizes. By about 1910, the 10-inch, 78 rpm shellac disc had become the most used format; the inherent technical limitations of the gramophone disc defined the standard format for commercial recordings in the early 20th century. The crude disc-cutting techniques of the time and the thickness of the needles used on record players limited the number of grooves per inch that could be inscribed on the disc surface, a high rotation speed was necessary to achieve acceptable recording and playback fidelity.
78 rpm was chosen as the standard because of the introduction of the electrically powered, synchronous turntable motor in 1925, which ran at 3600 rpm with a 46:1 gear ratio, resulting in a rotation speed of 78.26 rpm. With these factors applied to the 10-inch format and performers tailored their output to fit the new medium; the 3-minute single remained the standard into the 1960s, when the availability of microgroove recording and improved mastering techniques enabled recording artists to increase the duration of their recorded songs. The breakthrough came with Bob Dylan's "Like a Rolling Stone". Although CBS tried to make the record more "radio friendly" by cutting the performance into halves, separating them between the two sides of the vinyl disc, both Dylan and his fans demanded that the full six-minute take be placed on one side, that radio stations play the song in its entirety; as digital downloading and audio streaming have become more prevalent, it has become possible for every track on an album to be available separately.
The concept of a single for an album has been retained as an identification of a more promoted or more popular song within an album collection. The demand for music downloads skyrocketed after the launch of Apple's iTunes Store in January 2001 and the creation of portable music and digital audio players such as the iPod. In September 1997, with the release of Duran Duran's "Electric Barbarella" for paid downloads, Capitol Records became the first major label to sell a digital single from a well-known artist. Geffen Records released Aerosmith's "Head First" digitally for free. In 2004, Recording Industry Association of America introduced digital single certification due to significant sales of digital formats, with Gwen Stefani's "Hollaback Girl" becoming RIAA's first platinum digital single. In 2013, RIAA incorporated on-demand streams into the digital single certification. Single sales in the United Kingdom reached an all-time low in January 2005, as the popularity of the compact disc was overtaken by the then-unofficial medium of the music download.
Recognizing this, On 17 April 2005, Official UK Singles Chart added the download format to the existing format of physical CD singles. Gnarls Barkley was the first act to reach No.1 on this chart through downloads alone in April 2006, for their debut single "Crazy", released physically the following week. On 1 January 2007 digital downloads became eligible from the point of release, without the need for an accompanying physical. Sales improved in the following years, reaching a record high in 2008 that still proceeded to be overtaken in 2009, 2010 and 2011. Singles have been issued in various formats, including 7-inch, 10-inch, 12-inch vinyl discs. Other, less common, formats include singles on Digital Compact Cassette, DVD, LD, as well as many non-standard sizes of vinyl disc; the most common form of the vinyl single is the 45 or 7-inch. The names are derived from its play speed, 45 rpm, the standard diameter, 7 inches; the 7-inch 45 rpm record was released 31 March 1949 by RCA Victor as a smaller, more durable and higher-fidelity replacement for the 78 rpm shellac discs.

Pop music is a genre of popular music that originated in its modern form in the United States and United Kingdom during the mid-1950s. The terms "popular music" and "pop music" are used interchangeably, although the former describes all music, popular and includes many diverse styles. "Pop" and "rock" were synonymous terms until the late 1960s, when they became differentiated from each other. Although much of the music that appears on record charts is seen as pop music, the genre is distinguished from chart music. Pop music is eclectic, borrows elements from other styles such as urban, rock and country. Identifying factors include short to medium-length songs written in a basic format, as well as common use of repeated choruses, melodic tunes, hooks. David Hatch and Stephen Millward define pop music as "a body of music, distinguishable from popular and folk musics". According to Pete Seeger, pop music is "professional music which draws upon both folk music and fine arts music". Although pop music is seen as just the singles charts, it is not the sum of all chart music.
The music charts contain songs from a variety of sources, including classical, jazz and novelty songs. As a genre, pop music is seen to develop separately. Therefore, the term "pop music" may be used to describe a distinct genre, designed to appeal to all characterized as "instant singles-based music aimed at teenagers" in contrast to rock music as "album-based music for adults". Pop music continuously evolves along with the term's definition. According to music writer Bill Lamb, popular music is defined as "the music since industrialization in the 1800s, most in line with the tastes and interests of the urban middle class." The term "pop song" was first used in 1926, in the sense of a piece of music "having popular appeal". Hatch and Millward indicate that many events in the history of recording in the 1920s can be seen as the birth of the modern pop music industry, including in country and hillbilly music. According to the website of The New Grove Dictionary of Music and Musicians, the term "pop music" "originated in Britain in the mid-1950s as a description for rock and roll and the new youth music styles that it influenced".
The Oxford Dictionary of Music states that while pop's "earlier meaning meant concerts appealing to a wide audience since the late 1950s, pop has had the special meaning of non-classical mus in the form of songs, performed by such artists as the Beatles, the Rolling Stones, ABBA, etc." Grove Music Online states that " in the early 1960s,'pop music' competed terminologically with beat music, while in the US its coverage overlapped with that of'rock and roll'". From about 1967, the term “pop music” was used in opposition to the term rock music, a division that gave generic significance to both terms. While rock aspired to authenticity and an expansion of the possibilities of popular music, pop was more commercial and accessible. According to British musicologist Simon Frith, pop music is produced "as a matter of enterprise not art", is "designed to appeal to everyone" but "doesn't come from any particular place or mark off any particular taste". Frith adds that it is "not driven by any significant ambition except profit and commercial reward and, in musical terms, it is conservative".
It is, "provided from on high rather than being made from below... Pop is not a do-it-yourself music but is professionally produced and packaged". According to Frith, characteristics of pop music include an aim of appealing to a general audience, rather than to a particular sub-culture or ideology, an emphasis on craftsmanship rather than formal "artistic" qualities. Music scholar Timothy Warner said it has an emphasis on recording and technology, rather than live performance; the main medium of pop music is the song between two and a half and three and a half minutes in length marked by a consistent and noticeable rhythmic element, a mainstream style and a simple traditional structure. Common variants include the verse-chorus form and the thirty-two-bar form, with a focus on melodies and catchy hooks, a chorus that contrasts melodically and harmonically with the verse; the beat and the melodies tend to be simple, with limited harmonic accompaniment. The lyrics of modern pop songs focus on simple themes – love and romantic relationships – although there are notable exceptions.
Harmony and chord progressions in pop music are "that of classical European tonality, only more simple-minded." Clichés include the barbershop quartet-style blues scale-influenced harmony. There was a lessening of the influence of traditional views of the circle of fifths between the mid-1950s and the late 1970s, including less predominance for the dominant function. Throughout its development, pop music has absorbed influences from other genres of popular music. Early pop music drew on the sentimental ballad for its form, gained its use of vocal harmonies from gospel and soul music, instrumentation from jazz and rock music, orchestration from classical music, tempo from dance music, backing from electronic music, rhythmic elements from hip-hop music, spoken passages from rap. In the 1960s, the majority of mainstream pop music fell in two categories: guitar and bass groups or singers
A music download is the digital transfer of music via the Internet into a device capable of decoding and playing it, such as a home computer, MP3 player or smartphone. This term encompasses both legal downloads and downloads of copyrighted material without permission or legal payment. According to a Nielsen report, downloadable music accounted for 55.9% of all music sales in the US in 2012. By the beginning of 2011, Apple's iTunes Store alone made US$1.1 billion of revenue in the first quarter of its fiscal year. Paid downloads are sometimes encoded with Digital Rights Management that restricts copying the music or playing purchased songs on certain digital audio players, they are always compressed using a lossy codec, which reduces file size and bandwidth requirements. These music resources have been created as a response to expanding technology and needs of customers that wanted easy, quick access to music, their business models respond to the "download revolution" by making legal services attractive for users.
Legal music downloads have faced a number of challenges from artists, record labels and the Recording Industry Association of America. In July 2007, the Universal Music Group decided not to renew their long-term contracts with iTunes; this decision was based upon the issue of pricing of songs, as Universal wanted to be able to charge more or less depending on the artist, a shift away from iTunes' standard—at the time—99 cents per song pricing. Many industry leaders feel that this is only the first of many show-downs between Apple Inc. and the various record labels. According to research by the website TorrentFreak, 38% of Swedish artists support file share downloading and claim that it helps artists in early career stages; the Swedish rock group Lamont has profited from file sharing. The Recording Industry Association of America oversees about 85% of published music production and manufacturing in the United States, they work to protect musicians while supporting the First Amendment rights. Their stated goal is to support artists' creativity and help them not be cheated out of money by illegal downloading.
The Recording Industry Association of America launched its first lawsuits on 8 September 2003, against individuals who illegally downloaded music files from the Kazaa FastTrack network. Two years after it began, the campaign survived at least one major legal challenge; the RIAA said it filed 750 suits in February 2006 against individuals downloading music files without paying for them in hopes of putting an end to Internet music piracy. The RIAA hopes their campaign will force people to respect the copyrights of music labels and minimize the number of illegal downloads; the Official Charts Company began to incorporate downloads in the UK Singles Chart on 17 April 2005, at which time Radio 1 stopped broadcasting the separate download chart, although the chart is still compiled. This was on condition that the song must have a physical media release at the same time. Music downloads have been measured by the Official Charts Company since 2004 and included in the main UK Singles Chart from 2005.
The most downloaded song in the UK is "Happy" by Pharrell Williams with over 1.8 million downloads. In November 2005, the record for the best-selling downloaded single in the United States was held by Gwen Stefani's "Hollaback Girl", which sold over one million downloads, making it the first song to achieve platinum download status; as of July 2012, the record for the best-selling downloaded single in the United States on the iTunes Store is held by The Black Eyed Peas's "I Gotta Feeling", which has sold over 8 million downloads. Soon after his death in 2009, Michael Jackson became the first artist to sell over one million songs downloaded via the Internet in one week. However, Adele marks the most downloads sold by a single song in a week, with "Hello" selling 1.12 million copies in November 2015. Eminem's seventh studio album, became the first album to sell one million digital copies. Beyoncé's self-titled fifth studio album became the fastest-selling album within 24 hours in iTunes history after its release in December 2013.
Within 24 hours of availability, the album sold 430,000 digital copies. Adele's third studio album 25 became the fastest-selling album in a week iTunes history after it was released on 20 November 2015, it sold 1.64 million digital copies in its first week. In 2006, the Recording Industry Association of Japan began issuing certifications for digitally released music in Japan, compiling data from the early 2000s onwards; the best-selling song is Fukushima-based vocal group Greeeen's song "Kiseki", certified for being downloaded four million times between 2008 and 2015, followed by R&B singer Thelma Aoyama's "Soba ni Iru ne" featuring rapper SoulJa, certified for three million downloads between 2008 and 2014. Greeeen's song "Ai Uta" ranks as the third highest certified song, with 2.5 million downloads tracked between 2007 and 2009. Two more songs have sold more than two million paid downloads: Ayaka's "Mikazuki" and Kobukuro's "Tsubomi"; the most successful ringtone in Japan is Moldovan-Romanian band O-Zone's "Dragostea din tei", known locally as "Koi no Maiahi", certified as having four million units sold.
In Japan, only two albums have received digital certifications by the RIAJ. The first was Songs for Japan, a charity compilation album raising profits for the 2011 Tōhoku earthquake and tsunami, certified gold for 100,000 downloa
Eurodance is a genre of electronic dance music that originated in the late 1980s in Europe. It combines many elements of Hi-NRG, house music and Euro disco; this genre of music is influenced by the use of rich melodic vocals, either by itself or inclusively with rapped verses. This, combined with cutting-edge synthesizer, strong bass rhythm and melodic hooks, establishes the core foundation of Eurodance music. Eurodance production continues to evolve with a more modernized style. Eurodance music originated in the late 1980s in central Europe in Germany, where rave parties were becoming popular. By 1987, a German party scene, started by Tauseef Alam, based on the Chicago House sound was well established; the following year saw acid house making as significant an impact on popular consciousness in Germany and Central Europe as it had in England. In 1989 German DJs Westbam and Dr. Motte established the Ufo Club, an illegal party venue, co-founded the Love Parade; the parade first occurred in July 1989.
It was conceived as a political demonstration for peace and international understanding through love and music. On 19 July 1989 Black Box's single Ride On Time was released; the song spent six weeks at No. 1 in the United Kingdom and it was the UK's best-selling single of 1989. It contained the Korg M1's "house piano". On 27 September 1989 Technotronic's single Pump Up the Jam was released, it reached number one in Belgium and Spain, it popularised the house variant called hip house in Europe. On 9 November 1989 the Berlin Wall fell, free underground Techno parties mushroomed in East Berlin, a rave scene comparable to that in the UK was established. East German DJ Paul van Dyk has remarked that the Techno-based rave scene was a major force in re-establishing social connections between East and West Germany during the unification period. In the same year, German producers Michael Münzing and Luca Anzilotti formed the Snap! Project in Frankfurt. Snap! Songs combined rap and soul vocals adding rhythm by using computer technology and mixing electronic sounds and drums.
By doing so a new genre was born: Eurodance. Their first single, "The Power", released in 1990, reached number one in the Netherlands, Spain and the United Kingdom, it helped to popularise the genre within Europe. In the following years, other Eurodance acts formed in Frankfurt, including La Bouche and Spoon, Magic Affair and Culture Beat, new groups popped up all over Europe; the popularity of the genre expanded to East Asian nations such as Japan, South Korea and Taiwan. The term "Eurodance" became associated with a specific style of European dance music. During its golden years in the mid-1990s, it was referred as "Euro-NRG". While some use a much broader definition of what is considered "Eurodance", over time, the term came to refer to an NRG-based genre from the 1990s which included a solo vocalist or a rapper/vocalist duet. Although the term was used to describe only European dance music productions, there are some examples of acts from the 1990s produced in America, which followed the same music style and became popular in Europe, nowadays are referred to as Eurodance music.
Most Eurodance is characterized by synthesizer riffs, one or more vocals with simple chorus, one or more rap parts, sampling and a strong beat. Sometimes non-rap vocals are used. Eurodance carries a positive, upbeat attitude; the early to mid-1990s Eurodance vocals were done by a solo vocalist or a mixed rapper-vocalist duet. Many groups used variations of the rapper-vocalist theme, such as a German rapper with American singers, or the use of reggae rap as in Ice MC and Fun Factory, or scat singing as in Scatman John. Solo singing artists such as Alexia, Lynda Thomas, Corona, Whigfield, Double You, DJ BoBo contributed to the genre. Eurodance lyrics are always sung in English, regardless of the artist's nationalities. All Eurodance emphasizes percussion and rhythm; the tempo is around 140 beats per minute, but may vary from 110 to 150. Most Eurodance is melody-driven. Unlike most pop music, written in major keys, most Eurodance songs are in minor keys to techno. This, along with positive lyrics, helps contribute to the overall powerful and emotional sound of Eurodance.
Besides the contribution of the female or male vocals, there is a noticeable use of rapid synthesizer arpeggios. From the early to mid-1990s, Eurodance was popular in Europe. For example, in Italy there were seven singles in the top ten of the chart at the end of May 1995. By the late 1990s, the popularity of this genre had started to decline slowly. At this time, the classic Eurodance sound morphed into progressive house. In the 2000s, the mainstream music industry in Europe moved away from Eurodance in favour of other styles of dance music such as nu-disco, electro house, dance-pop and R&B. In recent years till the present day in 2019, classic Eurodance songs continue to be loved by many and are aired on some of the most popular radio stations and TV music channels across Europe. Eurodance was popular in Australia in the early/mid 1990s during the time of the emergence of warehouse
A music genre is a conventional category that identifies some pieces of music as belonging to a shared tradition or set of conventions. It is to be distinguished from musical form and musical style, although in practice these terms are sometimes used interchangeably. Academics have argued that categorizing music by genre is inaccurate and outdated. Music can be divided into different genres in many different ways; the artistic nature of music means that these classifications are subjective and controversial, some genres may overlap. There are varying academic definitions of the term genre itself. In his book Form in Tonal Music, Douglass M. Green distinguishes between form, he lists madrigal, canzona and dance as examples of genres from the Renaissance period. To further clarify the meaning of genre, Green writes, "Beethoven's Op. 61 and Mendelssohn's Op. 64 are identical in genre – both are violin concertos – but different in form. However, Mozart's Rondo for Piano, K. 511, the Agnus Dei from his Mass, K. 317 are quite different in genre but happen to be similar in form."
Some, like Peter van der Merwe, treat the terms genre and style as the same, saying that genre should be defined as pieces of music that share a certain style or "basic musical language." Others, such as Allan F. Moore, state that genre and style are two separate terms, that secondary characteristics such as subject matter can differentiate between genres. A music genre or subgenre may be defined by the musical techniques, the style, the cultural context, the content and spirit of the themes. Geographical origin is sometimes used to identify a music genre, though a single geographical category will include a wide variety of subgenres. Timothy Laurie argues that since the early 1980s, "genre has graduated from being a subset of popular music studies to being an ubiquitous framework for constituting and evaluating musical research objects". Among the criteria used to classify musical genres are the trichotomy of art and traditional musics. Alternatively, music can be divided on three variables: arousal and depth.
Arousal reflects the energy level of the music. These three variables help explain why many people like similar songs from different traditionally segregated genres. Musicologists have sometimes classified music according to a trichotomic distinction such as Philip Tagg's "axiomatic triangle consisting of'folk','art' and'popular' musics", he explains that each of these three is distinguishable from the others according to certain criteria. The term art music refers to classical traditions, including both contemporary and historical classical music forms. Art music exists in many parts of the world, it emphasizes formal styles that invite technical and detailed deconstruction and criticism, demand focused attention from the listener. In Western practice, art music is considered a written musical tradition, preserved in some form of music notation rather than being transmitted orally, by rote, or in recordings, as popular and traditional music are. Most western art music has been written down using the standard forms of music notation that evolved in Europe, beginning well before the Renaissance and reaching its maturity in the Romantic period.
The identity of a "work" or "piece" of art music is defined by the notated version rather than by a particular performance, is associated with the composer rather than the performer. This is so in the case of western classical music. Art music may include certain forms of jazz, though some feel that jazz is a form of popular music. Sacred Christian music forms an important part of the classical music tradition and repertoire, but can be considered to have an identity of its own; the term popular music refers to any musical style accessible to the general public and disseminated by the mass media. Musicologist and popular music specialist Philip Tagg defined the notion in the light of sociocultural and economical aspects: Popular music, unlike art music, is conceived for mass distribution to large and socioculturally heterogeneous groups of listeners and distributed in non-written form, only possible in an industrial monetary economy where it becomes a commodity and in capitalist societies, subject to the laws of'free' enterprise... it should ideally sell as much as possible.
Popular music is found on most commercial and public service radio stations, in most commercial music retailers and department stores, in movie and television soundtracks. It is noted on the Billboard charts and, in addition to singer-songwriters and composers, it involves music producers more than other genres do; the distinction between classical and popular music has sometimes been blurred in marginal areas such as minimalist music and light classics. Background music for films/movies draws on both traditions. In this respect, music is like fiction, which draws a distinction between literary fiction and popular fiction, not always precise. Country music known as country and western, hillbilly music, is a genre of popular music that originated in the southern United States in the early 1920s; the polka is a Czech dance and genre of dance music familiar throughout Europe and the Americas. Rock music is a broad genre of popular music that originated as "rock and roll" in the United States in the early 1950s, developed into a range of different styles in the 1960s and particular
