YouTube originally offered videos at only one quality level, displayed at a resolution of 320×240 pixels using the Sorenson Spark codec (a variant of H.263),[86][87] with mono MP3 audio.[88] In June 2007, YouTube added an option to watch videos in 3GP format on mobile phones.[89] In March 2008, a high-quality mode was added, which increased the resolution to 480×360 pixels.[90] In November 2008, 720p HD support was added. At the time of the 720p launch, the YouTube player was changed from a 4:3 aspect ratio to a widescreen 16:9.[91] With this new feature, YouTube began a switchover to H.264/MPEG-4 AVC as its default video compression format. In November 2009, 1080p HD support was added. In July 2010, YouTube announced that it had launched a range of videos in 4K format, which allows a resolution of up to 4096×3072 pixels.[92][93] In June 2015, support for 8K resolution was added, with the videos playing at 7680×4320 pixels.[94] In November 2016, support for HDR video was added which can be encoded with Hybrid Log-Gamma (HLG) or Perceptual Quantizer (PQ).[95] HDR video can be encoded with the Rec. 2020 color space.[96]
If hookups are your thing, Grindr and Tinder offer the prospect of casual sex within the hour. The phrase If something exists, there is porn of it used to be a clever internet meme; now it’s a truism. BDSM plays at the local multiplex—but why bother going? Sex is portrayed, often graphically and sometimes gorgeously, on prime-time cable. Sexting is, statistically speaking, normal.

One reason is that it caters to a narrow audience of young viewers. Music videos are its most popular content. YouTube’s stars remain relatively unknown. Felix “PewDiePie” Kjellberg is the biggest star, with 35 million subscribers to his wacky videogame montages. Even Ms. Wojcicki hadn’t heard of him before joining YouTube, she told a conference last fall.
Soon after the snows of 1977 began to thaw, the residents of Greenfield, Massachusetts, received a strange questionnaire in the mail. “Try to recall the number of times you became annoyed and/or angry during the past week,” the survey instructed. “Describe the most angry of these experiences.” One woman knew her answer: Recently, her husband had bought a new car. Then he had driven it to his mistress’s house so she could admire the purchase. When the wife found out, she was livid. Furious. Her rage felt like an eruption she couldn’t control.
On September 13, 2016, YouTube launched a public beta of Community, a social media-based feature that allows users to post text, images (including GIFs), live videos and others in a separate "Community" tab on their channel.[121] Prior to the release, several creators had been consulted to suggest tools Community could incorporate that they would find useful; these YouTubers included Vlogbrothers, AsapScience, Lilly Singh, The Game Theorists, Karmin, The Key of Awesome, The Kloons, Peter Hollens, Rosianna Halse Rojas, Sam Tsui, Threadbanger and Vsauce3.[122]

YouTube featured an April Fools prank on the site on April 1 of every year from 2008 to 2016. In 2008, all links to videos on the main page were redirected to Rick Astley's music video "Never Gonna Give You Up", a prank known as "rickrolling".[236][237] The next year, when clicking on a video on the main page, the whole page turned upside down, which YouTube claimed was a "new layout".[238] In 2010, YouTube temporarily released a "TEXTp" mode which transformed colors in videos to random uppercase letters "in order to reduce bandwidth costs by $1 per second."[239] The next year, the site celebrated its "100th anniversary" with a range of sepia-toned silent, early 1900s-style films, including a parody of Keyboard Cat.[240] In 2012, clicking on the image of a DVD next to the site logo led to a video about a purported option to order every YouTube video for home delivery on DVD.[241] In 2013, YouTube teamed up with satirical newspaper company The Onion to claim that the video sharing website was launched as a contest which had finally come to an end, and would announce a winner of the contest when the site went back up in 2023.[242] In 2014, YouTube announced that it was responsible for the creation of all viral video trends, and revealed previews of upcoming internet memes, such as "Clocking", "Kissing Dad", and "Glub Glub Water Dance".[243] The next year, YouTube added a music button to the video bar that played samples from "Sandstorm" by Darude.[244] In 2016, YouTube introduced an option to watch every video on the platform in 360-degree mode with Snoop Dogg.[245]
Infrastructure costs -- The concept of free user services and scaling to eventually make them pay depends on the negligible price of adding additional consumers. But video is demanding of bandwidth and storage. Even if those are cheap in general, once you're handling as much material as the service does, it means big expenses for infrastructure. Although those costs won't scale linearly with the increased number of users, they do grow.

Google does not provide detailed figures for YouTube's running costs, and YouTube's revenues in 2007 were noted as "not material" in a regulatory filing.[279] In June 2008, a Forbes magazine article projected the 2008 revenue at $200 million, noting progress in advertising sales.[280] In January 2012, it was estimated that visitors to YouTube spent an average of 15 minutes a day on the site, in contrast to the four or five hours a day spent by a typical US citizen watching television.[28] In 2012, YouTube's revenue from its ads program was estimated at $3.7 billion.[281] In 2013 it nearly doubled and estimated to hit $5.6 billion according to eMarketer,[281][282][283] while others estimated $4.7 billion.[281] The vast majority of videos on YouTube are free to view and supported by advertising.[56] In May 2013, YouTube introduced a trial scheme of 53 subscription channels with prices ranging from $0.99 to $6.99 a month.[284] The move was seen as an attempt to compete with other providers of online subscription services such as Netflix and Hulu.[56] In 2017, viewers on average watch YouTube on mobile devices for more than an hour every day.[285]

YouTube has enabled people to more directly engage with government, such as in the CNN/YouTube presidential debates (2007) in which ordinary people submitted questions to U.S. presidential candidates via YouTube video, with a techPresident co-founder saying that Internet video was changing the political landscape.[261] Describing the Arab Spring (2010– ), sociologist Philip N. Howard quoted an activist's succinct description that organizing the political unrest involved using "Facebook to schedule the protests, Twitter to coordinate, and YouTube to tell the world."[262] In 2012, more than a third of the U.S. Senate introduced a resolution condemning Joseph Kony 16 days after the "Kony 2012" video was posted to YouTube, with resolution co-sponsor Senator Lindsey Graham remarking that the video "will do more to lead to (Kony's) demise than all other action combined."[263]
So, predictably, by the time it was 10 a.m., I had made and consumed two cups of coffee, taken out the trash, cleaned my room while taking a deliberately slow approach to folding my shirts, gone on a walk outside to clear my head, had a thing of yogurt and fruit to reward the physical exertion, sent an email to my aunt and sister, read about 100 Tweets (favorited three; written and deleted one), despaired at my lack of progress, comforted myself by eating a second breakfast, opened several tabs from on my browser ... and written absolutely nothing.
Individuals and businesses make millions of dollars through YouTube advertising, but there are risks to using a platform controlled by another company. Not only is there a chance that a change in Google's search algorithms could make or break video traffic, but Google also takes a hefty 45 percent cut of revenue from video advertising. Nevertheless, YouTube is a massive platform and is the world's second largest search engine after Google, which includes YouTube videos in search results. If the benefits of reaching YouTube's large audience and having Google handle the most labor-intensive parts of building an advertising network outweigh the costs and risks, this platform is a great resource for turning videos into cash.
In 2013, YouTube introduced an option for channels with at least a thousand subscribers to require a paid subscription in order for viewers to watch videos.[300][301] In April 2017, YouTube set an eligibility requirement of 10,000 lifetime views for a paid subscription.[302] On January 16, 2018, the eligibility requirement for monetization was changed to 4,000 hours of watchtime within the past 12 months and 1,000 subscribers.[302] The move was seen as an attempt to ensure that videos being monetized did not lead to controversy, but was criticized for penalizing smaller YouTube channels.[303]
This means that if someone skips an ad, or is running an ad blocker, then you don’t get paid for that view. This makes estimating the amount of views a video has and how much a user makes off of the video very challenging. It also depends if it’s a video ad at the front of your video, or just a box at the bottom of your page; this determines how many people interact with your ad and the amount of money that can be made.

In January 2018, the 23-year-old elder Paul brother was kicked off YouTube’s Google Preferred program, which gives favorable ad rates to popular channels, after he filmed a video in Japan that showed an apparent suicide hanging from a tree. He apologized. His income from videos (pratfalls, pranks) and brand deals took a hit, but loyal fans kept his hefty merchandise business afloat.

YouTube Go is an Android app aimed at making YouTube easier to access on mobile devices in emerging markets. It is distinct from the company's main Android app and allows videos to be downloaded and shared with other users. It also allows users to preview videos, share downloaded videos through Bluetooth, and offers more options for mobile data control and video resolution.[225]
In May 2011, 48 hours of new videos were uploaded to the site every minute,[23] which increased to 60 hours every minute in January 2012,[23] 100 hours every minute in May 2013,[24][25] 300 hours every minute in November 2014,[26] and 400 hours every minute in February 2017.[27] As of January 2012, the site had 800 million unique users a month.[28] It is estimated that in 2007 YouTube consumed as much bandwidth as the entire Internet in 2000.[29] According to third-party web analytics providers, Alexa and SimilarWeb, YouTube is the second-most visited website in the world, as of December 2016; SimilarWeb also lists YouTube as the top TV and video website globally, attracting more than 15 billion visitors per month.[1][30][31] In October 2006, YouTube moved to a new office in San Bruno, California.[32]
