Facebook (FB) , which trades for about nine times its 2018 revenue consensus, is still seeing 40%-plus revenue growth and has some big growth levers left to press, is arguably a better comp for YouTube, given its business model, network effect and market dominance. But Facebook is quite profitable -- in spite of heavy spending on data centers and content security, Facebook's 2018 net income consensus stands at $22.5 billion -- and based on comments made by YouTube CEO Susan Wojcicki and others -- YouTube's profits might still be minimal thanks to large data center and content investments.
Watching my daughter play with my phone is a horrifying experience, precisely because her mimicry of adult behaviors is already so accurate. Her tiny fingers poke at buttons, pinch to zoom, endlessly scroll. It’s as though she’s grown a new brain from her fingertips. Most parents feel some version of this horror. Watching them poke and pinch at our devices, we realize that these rectangles of light and compulsion are not going away, and we are all dosing ourselves with their pleasures and conveniences without knowing the consequences.
The YouTube interface suggests which local version should be chosen on the basis of the IP address of the user. In some cases, the message "This video is not available in your country" may appear because of copyright restrictions or inappropriate content.[200] The interface of the YouTube website is available in 76 language versions, including Amharic, Albanian, Armenian, Bengali, Burmese, Khmer, Kyrgyz, Laotian, Mongolian, Persian and Uzbek, which do not have local channel versions. Access to YouTube was blocked in Turkey between 2008 and 2010, following controversy over the posting of videos deemed insulting to Mustafa Kemal Atatürk and some material offensive to Muslims.[201][202] In October 2012, a local version of YouTube was launched in Turkey, with the domain youtube.com.tr. The local version is subject to the content regulations found in Turkish law.[203] In March 2009, a dispute between YouTube and the British royalty collection agency PRS for Music led to premium music videos being blocked for YouTube users in the United Kingdom. The removal of videos posted by the major record companies occurred after failure to reach agreement on a licensing deal. The dispute was resolved in September 2009.[204] In April 2009, a similar dispute led to the removal of premium music videos for users in Germany.[205]
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]
The Hawaii native (real name Mark Fischbach) launched his YouTube channel in 2012 when he was a biomedical-engineering student at the University of Cincinnati. He was going through tough times: He’d broken up with his girlfriend, been laid off from his desk job and had an adrenal-gland tumor removed that surgeons found when they went to take out his appendix.   
On January 27, 2015, YouTube announced that HTML5 would be the default playback method on supported browsers. YouTube used to employ Adobe Dynamic Streaming for Flash,[76] but with the switch to HTML5 video now streams video using Dynamic Adaptive Streaming over HTTP (MPEG-DASH), an adaptive bit-rate HTTP-based streaming solution optimizing the bitrate and quality for the available network.[77]

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.”
YouTube offers users the ability to view its videos on web pages outside their website. Each YouTube video is accompanied by a piece of HTML that can be used to embed it on any page on the Web.[123] This functionality is often used to embed YouTube videos in social networking pages and blogs. Users wishing to post a video discussing, inspired by or related to another user's video are able to make a "video response". On August 27, 2013, YouTube announced that it would remove video responses for being an underused feature.[124] Embedding, rating, commenting and response posting can be disabled by the video owner.[125]
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.”

This year, Heather Hund and her family will gather in West Texas on December 25 and solidify a new Christmas tradition, in which each relative is randomly assigned to give a gift to another family member and to a house pet. “The rules are basically a regift for the human and then $10 for the pet,” Hund told me. “And my 18-month-old son got put in [the latter] category too, so it’s small humans and small animals.”

For any well-meaning kids’ producer, one model to look to for inspiration is Fred Rogers—PBS’s Mister Rogers. Rogers didn’t have any deep academic background in children’s development, but early on, he grasped the educational possibilities of the new medium, and in the 15 years between the first children’s show he produced and the national premiere of Mister Rogers’ Neighborhood, he worked constantly to make it better for kids. ChuChu could well be going through a similar stage now. Founded just five years ago, it’s encountering a different, and tougher, media landscape than Rogers did—but his path is still worth following.

But there is something the company could do immediately to improve the situation. YouTube knows that I—and tens of millions of other people—have watched lots of videos made for toddlers, but it has never once recommended that I switch to YouTube Kids. Think of how hard Facebook works to push users from Instagram onto Facebook and vice versa. Why not try to get more families onto the YouTube Kids app? (Malik Ducard, YouTube’s global head of family and learning, said in a statement that YouTube has “worked hard to raise awareness of the YouTube Kids app through heavy promotion. These promos have helped drive our growth. Today, YouTube Kids has over 14 million weekly viewers and over 70 billion views.”)
It's the perfect option for videos managed by charities and nonprofits, but even for-profit businesses and independent creatives can publish videos and YouTube Live streams that encourage contributions from their audience. Streaming platforms such as Twitch.tv, which webcasts video games and general interest content, sees accounts that are two years or older make $80 in "tips" per year on average.
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. 
6. Meet up with fans in the real world: Meetups and similar events let YouTubers connect with viewers and sell merchandise. They’re usually best suited to those with active and engaged subscribers. Those with smaller audiences might want to skip ticketed events and bank on merchandise sales instead. Or if, for example, your videos teach viewers how to draw, you could set up a free class at a local park and sell your book of drawing techniques afterward.
YouTube earns advertising revenue from Google AdSense, a program which targets ads according to site content and audience. The vast majority of its videos are free to view, but there are exceptions, including subscription-based premium channels, film rentals, as well as YouTube Premium, a subscription service offering ad-free access to the website and access to exclusive content made in partnership with existing users.
