Typically only offered to large YouTube channels with a wide audience (although not exclusively), another big way to earn cash through YouTube is to get sponsored deals with companies that will pay you to promote or mention their products in your videos. You can earn money this way either as a lump sum of cash the company will pay you for the deal, clicks on the company's link, or on a per-view basis. 
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]
Not to put too fine a point on it, but this is almost precisely the problem that the rest of the media world finds itself in. Because quality is hard to measure, the numbers that exist are the ones that describe attention, not effect: views, watch time, completion rate, subscribers. YouTube uses those metrics, ostensibly objectively, when it recommends videos. But as Theodore Porter, the great historian of science and technology, put it in his book Trust in Numbers, “Quantification is a way of making decisions without seeming to decide.”
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.
In December 2012, two billion views were removed from the view counts of Universal and Sony music videos on YouTube, prompting a claim by The Daily Dot that the views had been deleted due to a violation of the site's terms of service, which ban the use of automated processes to inflate view counts. This was disputed by Billboard, which said that the two billion views had been moved to Vevo, since the videos were no longer active on YouTube.[393][394] On August 5, 2015, YouTube removed the feature which caused a video's view count to freeze at "301" (later "301+") until the actual count was verified to prevent view count fraud.[395] YouTube view counts once again updated in real time.[396]
As it became clear that ChuChu videos were being watched by millions of people on six continents, Krishnan and Chandar started branching out into original songs and nursery rhymes, which Krishnan has been writing for the past couple of years. Their content runs the gamut, from an adaptation of “Here We Go Round the Mulberry Bush,” dedicated to tree planting as a way to fight global warming, to “Banana Song” (“Na na na banana / long and curved banana”).
It's a little awkward, so we'll get straight to the point: This Sunday we humbly ask you to defend Wikipedia's independence. We depend on donations averaging about $16.36. But 98% of our readers in the U.S. are not responding to our messages, and time is running out to help in 2018. If everyone reading this gave $2.75, we could keep Wikipedia thriving for years to come. The price of your Sunday coffee is all we need. When we made Wikipedia a non-profit, people warned us we'd regret it. But if Wikipedia were commercial, it would be a great loss. Wikipedia unites all of us who love knowledge: contributors, readers and the donors who keep us thriving. The heart and soul of Wikipedia is a community of people working to bring you unlimited access to reliable information. Please take a minute to help us keep Wikipedia growing. Thank you.
