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]
On the other side lie many, many YouTube users who visit the site for other reasons and other forms of entertainment, and who arguably aren’t interested in supporting the cult of personalities that might be said to represent “old-school” YouTube. Instead, they come to the site for music, memes, narrative media, instructional videos, and more general forms of content consumption and entertainment.
YouTube's policies on "advertiser-friendly content" restrict what may be incorporated into videos being monetized; this includes strong violence, language, sexual content, and "controversial or sensitive subjects and events, including subjects related to war, political conflicts, natural disasters and tragedies, even if graphic imagery is not shown", unless the content is "usually newsworthy or comedic and the creator's intent is to inform or entertain".[352] In September 2016, after introducing an enhanced notification system to inform users of these violations, YouTube's policies were criticized by prominent users, including Phillip DeFranco and Vlogbrothers. DeFranco argued that not being able to earn advertising revenue on such videos was "censorship by a different name". A YouTube spokesperson stated that while the policy itself was not new, the service had "improved the notification and appeal process to ensure better communication to our creators".[353][354][355]
Promote your videos. Only videos that record thousands of visitors and channels that update videos frequently make the cut for YouTube's Partner Program. Wait to apply until you've developed a following and have garnered thousands of hits for your channel and videos. Promote your videos on your blog, through forums, and wherever else it's possible to leave a link.
In February 2015, YouTube released a secondary mobile app known as YouTube Kids. The app is designed to provide an experience optimized for children. It features a simplified user interface, curated selections of channels featuring age-appropriate content, and parental control features.[60] Later on August 26, 2015, YouTube launched YouTube Gaming—a video gaming-oriented vertical and app for videos and live streaming, intended to compete with the Twitch.[61]
You will first have to build up your YouTube platform to gain more followers. While it is by no means a science to instantly get thousands of subscribers or views, by posting frequently, promoting your videos, and paying attention to engagement and demographics, you can see what performs well and curate your content to what your viewers seem to like. 
Also in November 2017, it was revealed in the media that many videos featuring children – often uploaded by the minors themselves, and showing innocent content – were attracting comments from pedophiles[376][377] and circulating on the dark web, with predators finding the videos by typing in certain keywords in Russian.[377] As a result of the controversy, which added to the concern about "Elsagate", several major advertisers whose ads had been running against such videos froze spending on YouTube.[378][369]
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 October 2010, Hurley announced that he would be stepping down as chief executive officer of YouTube to take an advisory role, and that Salar Kamangar would take over as head of the company.[51] In April 2011, James Zern, a YouTube software engineer, revealed that 30% of videos accounted for 99% of views on the site.[52] In November 2011, the Google+ social networking site was integrated directly with YouTube and the Chrome web browser, allowing YouTube videos to be viewed from within the Google+ interface.[53]
Where eyeballs go, money follows. “People giving up TV and getting video content through mobile devices is a huge trend, and brands are spending huge amounts to reach those audiences,” says Evan Asano, the CEO of MediaKix, an influencer marketing agency. “It’s a similar, if not bigger market for influencers than Instagram.” Another reason brands love YouTube is that its numbers are harder to fake. “You can buy views on YouTube, but it’s much more expensive than buying followers and likes on Instagram,” Asano says. “It’s pretty cost-prohibitive to drastically inflate a channel’s views on a consistent basis.”
Morgan Stanley told clients Feb. 5 that more disclosure about YouTube, as well as the smaller businesses lumped together on its balance sheet as “Other Bets,” could help investors see more value in the sum of these parts. Alphabet, which now has a market capitalization of roughly $708 billion could actually be a $1 trillion company, the bank’s analysts said.
Advertisers only pay when someone clicks an ad or watches for 30 seconds.  This is why you can’t tie your channel views to dollars.  If your video gets ten million views but nobody watches or click the ads, you don’t make any money.  This is how I’m able to make $1 per 25 views.  Advertisers pay big money to get their ad in front of specific and targeted audience.
There was some backlash over these new benchmarks, but frankly, the vast majority of people who lost their monetization privileges weren’t earning much anyway. Most channels make somewhere between $1.50 and $3 per thousand views, depending on their content and audience, and Google won’t even cut a paycheck for under $100 (or roughly 50,000 views — a pretty tall order for the average 14-year-old posting eyeliner tutorials). In other words, if you were looking for an easy side gig, YouTube was never the efficient choice.
Most videos enable users to leave comments, and these have attracted attention for the negative aspects of both their form and content. In 2006, Time praised Web 2.0 for enabling "community and collaboration on a scale never seen before", and added that YouTube "harnesses the stupidity of crowds as well as its wisdom. Some of the comments on YouTube make you weep for the future of humanity just for the spelling alone, never mind the obscenity and the naked hatred".[379] The Guardian in 2009 described users' comments on YouTube as:[380]

Five years on, ChuChu TV is a fast-growing threat to traditional competitors, from Sesame Street to Disney to Nickelodeon. With all its decades of episodes, well-known characters, and worldwide brand recognition, Sesame Street has more than 5 billion views on YouTube. That’s impressive, but ChuChu has more than 19 billion. Sesame Street’s main feed has 4 million subscribers; the original ChuChu TV channel has 19 million—placing it among the top 25 most watched YouTube channels in the world, according to the social-media-tracking site Social Blade—and its subsidiary channels (primarily ChuChu TV Surprise Eggs Toys and ChuChu TV Español) have another 10 million.
3. Check out YouTube Red: AdSense isn’t the only way partners can make money on YouTube. You can also make videos available on YouTube Red, which is the site’s ad-free subscription service. And if you have more than 1,000 active subscribers, you can put videos behind a paywall and enable Super Chat, which lets viewers pay to have their messages highlighted during a live stream. To use that feature, partners have to be older than 18.
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]
Apply to join the YouTube Partner Program when you feel confident in the interest and following your videos have garnered. There is no set following numbers needed to become a partner, but YouTube must see that your videos have interest and are growing a following before you're accepted. Sometimes YouTube will contact you directly about becoming a partner, especially if your videos have gone viral quickly. If not, you can apply on the YouTube partner page by entering personal information, describing a marketing plan, and defining your video genre.
If your end goal is to actually make money from videos, there’s a far better option than simply relying on your measly allocation of ad revenue. Instead, create a YouTube channel and build an audience. The primary goal is to engage this audience and build a brand name. Then, once you've established a reputation, begin driving traffic to your own landing pages where you can up-sell viewers with premium video content.

Among the specific findings, researchers demonstrated that Sesame Street improved children’s vocabulary, regardless of their parents’ education or attitudes. Another study found that regular adult TV stunted vocabulary development, while high-quality educational programs accelerated language acquisition. The most fascinating study began in the 1980s, when a University of Massachusetts at Amherst team installed video cameras in more than 100 homes, and had those families and hundreds of others keep a written log of their media diet. Following up more than a decade later, researchers found that “viewing educational programs as preschoolers was associated with higher grades, reading more books, placing more value on achievement, greater creativity, and less aggression.” On the flip side, violent programming led to lower grades among girls, in particular. The team was unequivocal about the meaning of these results: What kids watched was much more important than how much of it they watched. Or, as the researchers’ refutation of Marshall McLuhan’s famous aphorism went, “The medium is not the message: The message is.”

In any case, if you have incontrovertible evidence that YouTube is actually unprofitable today, and why that is (i.e. is it because they’re just investing all that profit back into growth, or are their upkeep costs truly just on the order of multiple billions of dollars?), would love to see it and adjust this accordingly. Doesn’t really change any of the points made though.

At the time of uploading a video, YouTube users are shown a message asking them not to violate copyright laws.[313] Despite this advice, there are still many unauthorized clips of copyrighted material on YouTube. YouTube does not view videos before they are posted online, and it is left to copyright holders to issue a DMCA takedown notice pursuant to the terms of the Online Copyright Infringement Liability Limitation Act. Any successful complaint about copyright infringement results in a YouTube copyright strike. Three successful complaints for copyright infringement against a user account will result in the account and all of its uploaded videos being deleted.[314][315] Organizations including Viacom, Mediaset, and the English Premier League have filed lawsuits against YouTube, claiming that it has done too little to prevent the uploading of copyrighted material.[316][317][318] Viacom, demanding $1 billion in damages, said that it had found more than 150,000 unauthorized clips of its material on YouTube that had been viewed "an astounding 1.5 billion times". YouTube responded by stating that it "goes far beyond its legal obligations in assisting content owners to protect their works".[319]
YouTube has focused on developing online personalities such as video game player PewDiePie, music video specialist Smosh and style guru Michelle Phan. Driving much of the traffic to YouTube, analysts say, are multichannel networks such as Fullscreen, Maker Studios, SonyBMG and Whistle Sports. Google has bought stakes in multichannel networks such as Vevo and Machinima, analysts say, to ensure their content stays on its website.
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, and later from the 2004 Indian Ocean tsunami. Karim could not easily find video clips of either event online, which led to the idea of a video sharing site.[9] Hurley and Chen said that the original idea for YouTube was a video version of an online dating service, and had been influenced by the website Hot or Not.[8][10]
