Justin.tv is a website that allows users to produce and watch live streaming video. Like YouTube, Justin.tv user accounts are called "channels", and users are encouraged to broadcast a wide variety of user-generated live video content, called "broadcasts".
The company is an Internet startup based in San Francisco, California, with seed funding from Paul Graham of seed capital firm Y Combinator[1] and Series A funding with Alsop Louie Partners and Draper Associates[2]
Justin.tv is notable for its origin: The original Justin.tv was a single channel featuring founder Justin Kan, who broadcast his life 24/7 and popularized the term lifecasting. In 2007, Justin Kan stopped broadcasting and Justin.tv relaunched into its current form as a network of thousands of various channels.[3]
Users are permitted to broadcast to an unlimited number of people for free, and watching broadcasts do not require user registration. Broadcasts that are considered to contain potentially offensive content are available only to registered users over the age of 18. Broadcasts containing defamation, pornography, copyright violations, and material encouraging criminal conduct is prohibited by Justin.tv's terms of service.[4]

Company history
Lifecasting origins
Justin Kan speaking at Gnomedex in 2007
The original Justin.tv was a single channel featuring Justin Kan. Wearing a webcam attached to a baseball cap and streamed online via a laptop-backpack system designed by co-founder Kyle Vogt,[5] Kan decided he would wear the camera 24/7, and he began streaming continuous live video and audio at midnight March 19, 2007.[6]
The novelty of the concept attracted media attention, and Kan interviewed with Ann Curry on the Today Show (April 2, 2007), Tom Merritt on the first episode of CNET Live, Nightline (April 6, 2007) and World News Tonight (April 8, 2007). His lifecasting project has been compared to EDtv, Being John Malkovich, and The Truman Show.[7]
Expansion into platform
In the summer of 2007, Justin.tv became a platform for more than 60 different channels.[8] Beginning July 21, 2007, channels were listed by popularity, starting with the most popular on the left. The Directory at the top of each channel showed which channels were live and which were not broadcasting. Depending on the entry time, a visitor might have seen only a small selection of the available channels.
By August 2007, channels were being added at an average rate of two a day, with content covering both lifecasters and event streaming. The international locations range from Australia, Brazil, the United Kingdom, and France to the Netherlands and Sweden. In some cases, a lifecaster might travel from one country to another, as was the case when Lisa Batey traveled from Brooklyn to Tokyo and Kyoto in 2007 and 2008. Not all the participants have mobile equipment, however, and most simply transmit an image of themselves sitting at their computer. During this same time frame, singer-songwriter Jody Marie Gnant and others began lifecasting independent of Justin tv on Ustream and elsewhere.
On October 2, 2007, Justin.tv became an open network, allowing members of the public to register and broadcast.[9] By April 10, 2008, Kan stated in an Interview with Tom Merritt that Justin.tv had signed 30,000 broadcasting accounts.[10]
On March 14, 2008, Justin.tv added selectable Categories for broadcasters including: Featured, People & Lifecasting, Sports, Music & Radio, Gaming, News & Tech, Animals, Entertainment, Divas & Dudes.[11]
On Friday, June 27, 2008, Justin.tv added networks to the site, in which the user can make their own network with a forum, and officers that act as moderators for the network.[12]
On Monday, October 27, 2008, Justin.tv added Headlines which allows users to make reports on other broadcasters doing interesting things on the site, which then becomes edited and published for all users on the website to read and comment.[13]
For ease of use, a simplified redesign was introduced July 14, 2009.[14]
Technology
Justin.tv's broadcasting and viewing technology is based on Adobe Flash, a browser plug-in found in 95% of all personal computers,[15] and available for all of today's widely-used operating systems.
Users can broadcast directly from the site, with Justin.tv using Flash to auto-detect and stream from an attached webcam. Justin.tv also supports broadcasting using other third party software, most notably QuickTime Broadcaster, Camtwist, Flash Media Encoder, Wirecast, and VLC, to allow broadcasters to add effects or stream higher quality video.[16][17]
Justin.tv has no default video quality setting; instead, it sets bitrate on a case-by-case basis by testing the broadcaster's available bandwidth. The broadcaster can also manually adjust the bitrate before going live. While broadcasting from the browser, the maximum quality settings are 1000 kbps for video and 44 kHz for audio. As a comparison, YouTube High Quality video are 400-500 kbps, and 720p high definition video is approximately 2000 kbps.[18][19] The 1000 kbps limit can be exceeded by using alternate broadcasting methods, such as Flash Media Encoder and Quicktime Broadcaster, and 720p video in H.264 has been broadcast by some users.[20]
Following the Justin.tv re-design in July 2009, the default channel video size changed from a standard aspect ratio of 468 x 353 pixels to a widescreen 630 x 353 pixels.
Content accessibility
Like YouTube and other static video sites, Justin.tv allows each channel to be accompanied with an HTML snippet, which allows users to embed video onto pages outside the Justin.tv site.[21] Another snippet is given to embed the associated chatbox as well, thus allowing users to recreate the basic Justin.tv functionality on another page. Broadcasters have the option of disabling embedding for their specific channel.
Following the release of the API in August 2009, Justin.tv released Flash SWF files that allows developers to include Justin.tv video in Flash projects.[22]
Localization
While the primary Justin.tv site is in English, there is support for users to translate the site into other languages. 4 languages (Chinese, French, Latvian, and Spanish) have been translated completely, and an additional 14 are over 50% translated.[23]
Criticisms
Copyright
Justin.tv has been criticized for failing to ensure that its videos respect the law of copyright.[citation needed] Although Justin.tv complies with the Digital Millennium Copyright Act, [24] the nature of live broadcasting makes it difficult to take down streams in a timely manner.
In August 2009, Justin.tv announced a deal with Fox to actively filter streams in real-time.[25]
Lifecasting pranks
During the period when Justin.tv consisted solely of Justin Kan lifecasting, Justin became the target of several pranks. A viewer spoofed Justin's caller ID (publicly available on the site) using an IP Relay service. On March 21, 2007, the spoofer called the San Francisco Police Department and filed a false report about a stabbing in the apartment. The following day, someone reported a fire at the apartment. The San Francisco emergency services then put Justin.tv's number on a list which requires a confirmation call before responding to any emergencies.[26] Kan changed his number and kept the new one private.
Security
In July 2008, TheDefaced.org, a computer security group, released a non-malicious cross-site scripting (XSS) worm onto the Justin.tv site. After successfully propagating the virus, TheDefaced.org contacted Justin.tv programmers and worked with them to fix the vulnerability.[27]
[edit] Abusive users
On November 19, 2008, 19-year-old Abraham K. Biggs committed suicide while broadcasting to a room full of viewers on his Justin.tv channel by ingesting an overdose of benzodiazepine and opiates. He was also struggling with bipolar disorder[28][29] Biggs posted his suicide note online, as noted in The New York Times:
Much of the evidence of Mr. Biggs’s suicide and the reactions of users was removed from BodyBuilding.com and Justin.tv after his death was confirmed. But according to a chronology posted by a fellow user, Mr. Biggs listed the pills he had obtained and posted a suicide note that he had copied from another Web site. He directed people to his page on Justin.tv, where anyone can plug in a webcam and stream live video onto the Internet. In a chat room adjacent to the live video, the “joking and trash talking” continued after Mr. Biggs consumed the pills and lay on his bed, according to the user, who said he tried to reach the local police from his home in India.[30]
The man's father, Abraham Biggs, Sr., says those who watched share some blame in his son’s death.[31]
Justin.tv CEO Michael Seibel stated, "We regret that this has occurred and respect the privacy of the broadcaster and his family during this time. We have policies in place to discourage the distribution of distressing content and our community monitors the site accordingly. This content was flagged by our community, reviewed and removed according to our terms of service.”[32]
Justin.tvは基本24時間鑑賞してても飽きない事が売りではないでしょうか？
You Tubeと比べても動画時間など比べ物にならない位満足感がありますし、先取り動画もUPされていてとてもGoodです。
日本のアニメとかも欧米向きに放送されていて日本のアニメが世界で人気があるのが解ります。
その人は１３歳の時、海に飛び込もうとして飛び込んだら
下がテトラポットで、首に重度の障害を負い、車椅子生活を
しているんです。
しかし・・。
その人のある意味すごい所は、その前にも無茶して死にそうなケガを
しているのに無茶をやめない。
２０メートルの鉄塔に登る。
観光客に自分で獲ったさざえやアワビを売りつける。
とにかくやりたい放題の人なんです（笑）。
そんな彼もケガをして戸惑い悩んだ時もあったようですが、
１７歳の時にネットビジネスに出会い、そこでもバイタリティー
を発揮しあっという間に年収１億円のステージへと駆け上って
しまいます。
今回はその若干２１歳の和佐大輔さんが自分がどのように
ネットビジネスを始めて、成功し続けているかということと
和佐さんがやっているビジネスの素晴らしさ（好き＝仕事＝人生）
を無料で教えてくれます。
・・・・・！！。
・・・・・！！。
無料なんです。
無料動画ですので得することはあっても損はありません。
あなたが今回支払うのは１時間３０分という時間だけです。
そしてそのビジネスのどういったところが素晴らしいかと
簡単に言いますと、圧倒的な利益率の高さ、基本的にコーヒーを
飲みながらクーラーの効いた部屋でできるということ。
そして何といっても自分の好きなことを仕事にできるということ
なんです。
まあ私がこれ以上グダグダ言うよりも実際に無料動画を見て
もらったほうが良いですね。
この動画はホントにビジネスをやるすべての人、夢をあきらめない人
、現状に満足していない人、に見て欲しいです。
本音を言えば日本人全員見たほうが良いんじゃないかと思いますが。
でも、学校では教えてくれない、一般書籍には出ない情報だと
思いますので、あなたも和佐さんのような好奇心をもって
この機会に是非見てみてください。
