Most modern smartphones are capable of accessing YouTube videos, either within an application or through an optimized website. YouTube Mobile was launched in June 2007, using RTSP streaming for the video. Not all of YouTube's videos are available on the mobile version of the site. Since June 2007, YouTube's videos have been available for viewing on a range of Apple products. This required YouTube's content to be transcoded into Apple's preferred video standard, H.264, a process that took several months. YouTube videos can be viewed on devices including Apple TV, iPod Touch and the iPhone. In July 2010, the mobile version of the site was relaunched based on HTML5, avoiding the need to use Adobe Flash Player and optimized for use with touch screen controls. The mobile version is also available as an app for the Android platform. In September 2012, YouTube launched its first app for the iPhone, following the decision to drop YouTube as one of the preloaded apps in the iPhone 5 and iOS 6 operating system. According to GlobalWebIndex, YouTube was used by 35% of smartphone users between April and June 2013, making it the third-most used app.
Both In-Stream and Discovery are pay-per-view -- you pay YouTube a fixed rate for every view the ad receives -- and their return on investment (ROI) can be measured in Google AdWords. YouTube tallies one new "view" after 30 seconds of watching, or a click on the video as it's playing. If the video is less than 30 seconds, views are tallied from people who watch the entire ad.
When a video goes viral, YouTube is typically the driving force. As of 2011, YouTube is the third-ranked website globally, with hundreds of millions of users. While you might be using YouTube only to look up video of cute cats and funny pranks, other users actually generate a profit stream ranging from pocket money to money in the bank using their personal YouTube channels and the videos they create. If you want in on the YouTube gravy train, the first thing you should know is that it's not as easy as it may look.

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), with mono MP3 audio. In June 2007, YouTube added an option to watch videos in 3GP format on mobile phones. In March 2008, a high-quality mode was added, which increased the resolution to 480×360 pixels. 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. 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. In June 2015, support for 8K resolution was added, with the videos playing at 7680×4320 pixels. In November 2016, support for HDR video was added which can be encoded with Hybrid Log-Gamma (HLG) or Perceptual Quantizer (PQ). HDR video can be encoded with the Rec. 2020 color space.
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. 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. 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.
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 ESPN.com on my browser ... and written absolutely nothing.
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.
