YouTube does not usually offer a download link for its videos, and intends for them to be viewed through its website interface.[126] A small number of videos, can be downloaded as MP4 files.[127] Numerous third-party web sites, applications and browser plug-ins allow users to download YouTube videos.[128] In February 2009, YouTube announced a test service, allowing some partners to offer video downloads for free or for a fee paid through Google Checkout.[129] In June 2012, Google sent cease and desist letters threatening legal action against several websites offering online download and conversion of YouTube videos.[130] In response, Zamzar removed the ability to download YouTube videos from its site.[131]

Absent substantive oversight by regulators, in the late 1960s the calls for change entered a new, more creative phase. A group calling itself Action for Children’s Television began advocating for specific changes to programming for young kids. The Corporation for Public Broadcasting was formed in 1968 with government dollars. At the same time, Children’s Television Workshop began producing Sesame Street, and the forerunner to PBS, National Educational Television, began distributing Mister Rogers’ Neighborhood. These shows were tremendously successful in creating genuinely educational television. By the time children’s programming got swept up into the growing cable industry, the big channels had learned a lot from the public model, which they incorporated into shows such as Dora the Explorer and Blue’s Clues.

In a video posted on July 21, 2009,[112] YouTube software engineer Peter Bradshaw announced that YouTube users could now upload 3D videos. The videos can be viewed in several different ways, including the common anaglyph (cyan/red lens) method which utilizes glasses worn by the viewer to achieve the 3D effect.[113][114][115] The YouTube Flash player can display stereoscopic content interleaved in rows, columns or a checkerboard pattern, side-by-side or anaglyph using a red/cyan, green/magenta or blue/yellow combination. In May 2011, an HTML5 version of the YouTube player began supporting side-by-side 3D footage that is compatible with Nvidia 3D Vision.[116] The feature set has since been reduced, and 3D feature currently only supports red/cyan anaglyph with no side-by-side support.

For other YouTube creators, ad dollars only go so far, and a significant portion of revenue comes from sponsorships and “affiliate marketing” (when brands offer a commission on any sales or traffic that the creator’s content drives). Affiliates function pretty seamlessly through YouTube; anyone can include links to featured products in their video’s caption, and when audience members click through and buy them, that YouTube channel gets a small kickback. Many YouTubers prefer Amazon’s affiliate program, “Amazon associates,” although there are plenty more to choose from.
These two ends of a vast YouTube spectrum have clashed recently over two interesting and arguably related phenomena — both of which directly involve PewDiePie. The first is an ongoing battle that PewDiePie’s supporters have been waging in order to prevent his channel from being surpassed as the most popular one on YouTube. To keep this from happening, they’ve done everything from take out a Times Square billboard to reportedly hacking into 50,000 printers around the world in order to promote their “subscribe to PewDiePie” meme.
The second involves YouTube’s annual year-end “Rewind” video. The 2018 video, released on December 6 and described by YouTube as “a who’s who of internet culture,” omitted a number of popular YouTubers, most notably PewDiePie. In response, PewDiePie’s followers started a campaign encouraging people to vote down the video, with the result that within a matter of days, YouTube’s 2018 Rewind video has rapidly overtaken an eight-year-old Justin Bieber single to become the most disliked video in YouTube history, surpassing Bieber as of early Thursday morning at 9.8 million dislikes and counting. By Thursday afternoon, the dislikes had topped 10 million.
Facebook and Twitter could pose new challenges to YouTube, because those social networks are creating their own video services. “If YouTube wants to move towards strong profitability, or to be profitable, they are gong to have to take that advertising and make it part of any actual programming,” Bajarin said. “And one way to have control over all that is to create their own content.”

If streaming video followed the broadcast model, YouTube—in partnership with governments around the world—could also subsidize research into creating educational content specifically for YouTube, and into how best to deliver it to children. The company could invest in research to develop the best quantitative signals for educational programming, so it could recommend that programming to viewers its algorithm believes to be children. It could fund new educational programming, just as broadcasters have been required to do for decades. (“We are always looking for ways to build the educational content offering in the app in a way that’s really fun and engaging for kids,” Ducard said.)
And though they don't appear to be huge revenue contributors at this point, the YouTube Red and YouTube TV subscription services can't be overlooked when trying to value the company. Particularly YouTube Red, which provides ad-free YouTube, some original shows and access to the Google Play Music service for $10 per month, and which led YouTube to become the top-grossing U.S. iPhone app in March. Later this year, Google plans to replace Google Play Music -- in many ways Red's weak link -- with YouTube Remix, a music service that's fully integrated with YouTube.
In December 2011, YouTube launched a new version of the site interface, with the video channels displayed in a central column on the home page, similar to the news feeds of social networking sites.[54] At the same time, a new version of the YouTube logo was introduced with a darker shade of red, the first change in design since October 2006.[55] In May 2013, YouTube launched a pilot program for content providers to offer premium, subscription-based channels within the platform.[56][57] In February 2014, Susan Wojcicki was appointed CEO of YouTube.[58] In November 2014, YouTube announced a subscription service known as "Music Key", which bundled ad-free streaming of music content on YouTube with the existing Google Play Music service.[59]
Merchandise has become an increasingly important revenue stream for these top digital stars, almost all of whom (No. 1 being a notable exception) are in their 20s and 30s. Each of the 10 on our list now has a line of merchandise, whose blossoming sales help account for that 42% income increase from a year ago. “I’ve built this huge community, and we’ve made a lot of people laugh,” says Fischbach, who sees Cloak as the first step toward an empire built on assets more tangible than video uploads. For now, though, all those gaming clips serve as a force multiplier for the man known as Markiplier. Like any savvy businessman, he’s thinking ahead. “I’m not going to be able to make videos on YouTube forever,” he says. “I need to plan for the future.” 

To an adult, the appeal of ChuChu videos is not totally obvious. On the one hand, the songs are catchy, the colors are bright, and the characters are cute. On the other, the animation is two-dimensional and kind of choppy, a throwback to the era before Pixar. And there is a lot of movement; sometimes every pixel of the screen seems to be in motion. Krishnan and Chandar believe that any given shot needs to include many different things a child could notice: A bird flying in the background. Something wiggling. These things hold kids’ attention.
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]

I’ve tolerated all kind of s***t from Youtube... Youtube Rewind, Buzzfeed, SNL, censorship, the endless annoying mainstream music, tons of politic propaganda... god even the idea that I must to watch ads every 2 minutes (at this point I prefer turn on the old TV) but ever since tik tok ads invaded I feel I want to drink acid, pull my eyes off, blow my ears with firecrackers and die slowly... it’s TOO MUCH... I’ve never experience this level of despair for society. But anyways maybe I’m too old and bitter... even though i’m freaking 27!!

What kind of sales multiple does this fast-growing video juggernaut deserve? It's tough to think of a direct comparison. Netflix, which trades for over eight times its 2018 revenue consensus, relies on subscription revenue rather than ads. And whereas YouTube largely relies on ad revenue-sharing deals with content partners, Netflix directly pays its content partners for their material.
Some YouTube videos have themselves had a direct effect on world events, such as Innocence of Muslims (2012) which spurred protests and related anti-American violence internationally.[269] TED curator Chris Anderson described a phenomenon by which geographically distributed individuals in a certain field share their independently developed skills in YouTube videos, thus challenging others to improve their own skills, and spurring invention and evolution in that field.[254] Journalist Virginia Heffernan stated in The New York Times that such videos have "surprising implications" for the dissemination of culture and even the future of classical music.[270]

Facebook and Twitter could pose new challenges to YouTube, because those social networks are creating their own video services. “If YouTube wants to move towards strong profitability, or to be profitable, they are gong to have to take that advertising and make it part of any actual programming,” Bajarin said. “And one way to have control over all that is to create their own content.”
All that money is providing Google with more financial firepower to buy the rights to stream cable networks' shows on YouTube, too, which is likely to reel in even more viewers. It also is helping finance Alphabet's investments in projects such as self-driving cars and Internet-beaming balloons. That segment, known as Other Bets, lost $865 million during the July-September period, narrowing from a $980-million setback last year as Alphabet imposed more expense controls.

National Geographic magazine has announced the winning entries in its annual photo competition. The grand-prize winner this year is Jassen Todorov, who will take home a $5,000 prize for his aerial image of thousands of recalled Volkswagen and Audi cars in the Mojave Desert. The contest organizers have shared with us the top winners and honorable mentions below, selected from a pool of  nearly 10,000 entries. Captions are written by the individual photographers and lightly edited for content.
All YouTube users can upload videos up to 15 minutes each in duration. Users who have a good track record of complying with the site's Community Guidelines may be offered the ability to upload videos up to 12 hours in length, as well as live streams, which requires verifying the account, normally through a mobile phone.[78][79] When YouTube was launched in 2005, it was possible to upload longer videos, but a ten-minute limit was introduced in March 2006 after YouTube found that the majority of videos exceeding this length were unauthorized uploads of television shows and films.[80] The 10-minute limit was increased to 15 minutes in July 2010.[81] In the past, it was possible to upload videos longer than 12 hours. Videos can be at most 128 GB in size.[78] Video captions are made using speech recognition technology when uploaded. Such captioning is usually not perfectly accurate, so YouTube provides several options for manually entering the captions for greater accuracy.[82]
