How Youtube Become Reality Among People- Rewiews

YouTube is an online video-sharing platform headquartered in San Burno, California.three performers Paypal_employees Chad Hurley, Steven Chen,

and  Jawed Karim created the service in Feb 2005. Google brought the site in 2006 for US 41.6 billion;  youtube now operates as one of Google’s subsidiaries.

Youtube allows users to upload, use, share, add to playlist, comment on videos and subscribe to other users. It provides a wide verity of user-generated and corporate videos.

Available content including a video clip, TV show clip, music video, short and documentary films and other content such as video blogging, short original video, and educational videos.

Most content on youtube is uploaded by the individual, but media corporations including CBS, the BBC, VEVO offer some of their material on youtube as a part of the youtube partnership program.

Unregistered users can only watch videos on the sites, while registered users are allowed to upload an unlimited number of videos and comment on videos.

Background Of Youtube Creation:

YouTube was founded by Steve Chen, Chad Hurley, and Jawed Karim, who were all early employees of PayPal. Hurley had studied design a Indiana

University of Pennsylvania, and Chen and Karim studied computer science together at the University of Illinois at Urbana-Champaign.

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. 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. Difficulty in finding enough dating videos led to a change of plans, with the site’s founders deciding to accept uploads of any type of video.

According to a story that has often been repeated in the media, Hurley and Chen developed the idea for YouTube during the early months of 2005,

after they had experienced difficulty sharing videos that had been shot at a dinner party at Chen’s apartment in San Francisco.

Karim did not attend the party and denied that it had occurred, but Chen commented that the idea that YouTube was founded after a dinner party “was probably very strengthened by marketing ideas around creating a story that was very digestible”.

FEATURES OF YOUTUBE:

Video Technology:

YouTube primarily uses the VP9 and H.264/MPEG-4 AVC video formats, and the Dynamic Adaptive Streaming over HTTP protocol. By January 2019, YouTube had begun rolling out videos in V1 format.

Playback:

Previously, viewing YouTube videos on a personal computer required the Adobe Flash Player plug-in to be installed in the browser. In January 2010,

YouTube launched an experimental version of the site that used the built-in multimedia capabilities of web browsers supporting the HTML standard.

This allowed videos to be viewed without requiring Adobe Flash Player or any other plug-in to be installed. The YouTube site had a page that allowed supported browsers to opt into the HTML5 trial.

Only browsers that supported HTML5 Video using the MP4 or WebM (with VP8 video) formats could play the videos, and not all videos on the site were available.

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, 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.

3D videos:

In a video posted on July 21, 2009, YouTube software engineer Peter Bradshaw announced that users could now upload the 3D video.

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.

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. The feature set has since been reduced, and the 3D feature currently only supports red/cyan anaglyph with no side-by-side support.

User Features:

Community:

On September 13, 2016, the website launched a public beta of Community, a social media-based feature that allows users to post text,

images (including GIFs), live videos and others in a separate “Community” tab on their channel. Prior to the release, several creators had been consulted to suggest tools Community could incorporate that they would find useful;

these YouTubers included Vlogbrothers, AsapScience, Lilly Singh, The Game Theorists, Karmin, The Key of Awesome, The Koons, Peter Hollens, Rosianna Halse Rojas, Sam Tsui, Threadbanger and Vsauce3.

After the feature has been officially released, the community post feature gets activated automatically for every channel that passes a specific threshold of subscriber counts or already has more subscribers.

This threshold was lowered over time from 10000 subscribers to 1500 subscribers, to 1000 subscribers, which is the current threshold as of September 2019.

Channels that the community tab becomes enabled for, get their channel discussions (name prior to March 2013 “One channel layout” redesign finalization: “channel comments”) permanently erased, instead of co-existing or migrating.

YouTube TV:

On February 28, 2017, in a press announcement held at YouTube Space Los Angeles, the organizer announced the launch of YouTube TV, an over-the-top MVPD-style subscription service that would be available for United States customers at the price of US$35 per month.

Initially launching in five major markets (New York City, Los Angeles, Chicago, Philadelphia and San Francisco) on April 5, 2017, the service offers live streams of programming from the five major broadcast networks

(ABC, CBS, The CW, Fox, and NBC), as well as approximately 40 cable channels owned by the corporate parents of those networks,

the Walt Disney Company, CBS Corporation, 21st Century Fox, NBC Universal and Turner Broadcasting System (including among others Bravo, USA Network, Syfy, Disney Channel, CNN, Cartoon Network, Fox Sports 1, Freeform, FX, and ESPN).

Subscribers can also receive Showtime and Fox Soccer Plus as optional add-ons for an extra fee and can access YouTube Premium original content (YouTube TV does not include a YouTube Red subscription).

During the 2017 World Series (in which it was the presenting sponsor),  TV ads were placed behind the home plate. The trademarked red play button logo appeared at the center of the screen, mimicking YouTube’s interface.
