TwitterTwitter is a website, owned and operated by Twitter Inc., which offers a social networking and microblogging service which enables its users to send and read other users' messages called tweets. Tweets are text-based posts of up to 140 characters displayed on the user's profile page. Tweets are publicly visible by default, however senders can restrict message delivery to their friends list. Users may subscribe to other author tweets—this is known as following and subscribers are known as followers. As of late 2009, users can follow lists of authors instead of just following individual authors.[7][8] All users can send and receive tweets via the Twitter website, compatible external applications (such as, for smartphones), or by Short Message Service[9]phone service provider fees. The website is based in San Bruno, California near San FranciscoSan Antonio, Texas and Boston, Massachusetts. While the service is free, accessing it through SMS may incur (where the website was first based). Twitter also has servers and offices in (SMS) available in certain countries. Users can group posts together by topic or type by use of hashtags — words or phrases prefixed with a #.[30] Similarly, the letter d followed by a username@ sign followed by a username is used for mentioning or replying to other users.[31] allows users to send messages privately. Finally, the In late 2009, the "Twitter Lists" feature was added, making it possible for users to follow (as well as mention and reply to) lists of authors instead of individual authors.[7][8] Through SMS, users can communicate with Twitter through five gateway numbers: short codes for the United States, Canada, India, New Zealand, and an Isle of Man-based number for international use. There is also a short code in the United Kingdom which is only accessible to those on the Vodafone, O2[32] and Orange[33] networks. In India, since Twitter only supports tweets from Bharti Airtel,[34] an alternative platform called smsTweet[35] was set up by a user to work on all networks.[36] A similar platform called GladlyCast[37] exists for mobile phone users in Singapore, Malaysia and the Philippines. The messages were initially set to 140-character limit for compatibility with SMS messaging, introducing the shorthand notation and slang commonly used in SMS messages. The 140 character limit has also increased the usage of URL shortening services such as bit.ly, goo.gl, and tr.im, and content hosting services, such as Twitpic, memozu.com and NotePub to accommodate multimedia content and text longer than 140 characters. Twitter uses bit.ly for automatic shortening of all URLs posted on its website.  Flickr Flickr is an image hosting and video hosting website, web services suite, and online community created by Ludicorp and later acquired by Yahoo!. In addition to being a popular website for users to share and embed personal photographs, the service is widely used by bloggers to host images that they embed in blogs and social media. In September 2010, it reported that it was hosting more than 5 billion images. Twitter had 400,000 tweets posted per quarter in 2007. This grew to 100 million tweets posted per quarter in 2008. By the end of 2009, 2 billion tweets per quarter were being posted.[citation needed] By March 2010, Twitter recorded over 70,000 registered applications, according to the company.[22] In February 2010 that Twitter users were sending 50 million tweets per day.[23] In the first quarter of 2010, 4 billion tweets were posted.[citation needed] As of June 2010, about 65 million tweets are posted each day, equalling about 750 tweets sent each second, according to Twitter.[24]Twitter's usage spikes during prominent events. For example, a record was set during the 2010 FIFA World Cup when fans wrote 2,940 tweets per second in the 30 second period after Japan scored against Cameroon on 14 June 2010. The record was broken again when 3,085 tweets a second were posted after the Los Angeles Lakers' victory in the 2010 NBA Finals on 17 June 2010.[25]. When American singer Michael Jackson died on June 25, 2009, the Twitter server crashed after user's were updating their status to include the words "Michael Jackson" at a rate of 100,000 tweets per hour.[26] Twitter acquired application developer Atebits on April 11, 2010. Atebits had developed the Apple Design Award-winning Twitter client Tweetie for Mac and iPhone. The application, now called "Twitter" and distributed free of charge, is the official Twitter client for the iPhone.[27] Users can group posts together by topic or type by use of hashtags — words or phrases prefixed with a #.[30] Similarly, the letter d followed by a username@ sign followed by a username is used for mentioning or replying to other users.[31] allows users to send messages privately.

Three former PayPal employees created YouTube in February 2005.[3] The name and logo of the company are an allusion to the cathode ray tube, a display device used since the early days of electronic television.[citation needed]The company is based in San Bruno, California, and uses Adobe Flash Videouser-generated video content, including movie clips, TV clips, and music videos, as well as amateur content such as video blogging and short original videos. Most of the content on YouTube has been uploaded by individuals, although media corporations including CBS, BBC, VEVO and other organizations offer some of their material via the site, as part of the YouTube partnership program.[4] technology to display a wide variety of Unregistered users can watch the videos, while registered users are permitted to upload an unlimited number of videos. Videos that are considered to contain potentially offensive content are available only to registered users 18 and older. In November 2006, YouTube, LLC was bought by Google Inc. for $1.65 billion, and now operates as a subsidiary of Google. Copyrighted materialYouTube has been criticized for failing to ensure that uploaded videos comply with the law of copyright. At the time of uploading a video, YouTube users are shown a screen with the message "Do not upload any TV shows, music videos, music concerts or advertisements without permission, unless they consist entirely of content that you created yourself".[39] Despite this advice, there are still many unauthorized clips of copyrighted material on YouTube. YouTube does not view videos before they are posted online, and it is left to copyright holders to issue a takedown notice under the terms of the Digital Millennium Copyright Act.Organizations including Viacom, Mediaset and the English Premier League have filed lawsuits against YouTube, claiming that it has done too little to prevent the uploading of copyrighted material.[40][41][42] Viacom, demanding US$1 billion in damages, said that it had found more than 150,000 unauthorized clips of its material on YouTube that had been viewed "an astounding 1.5 billion times". YouTube responded by stating that it "goes far beyond its legal obligations in assisting content owners to protect their works". Since Viacom filed its lawsuit, YouTube has introduced a system called Video ID, which checks uploaded videos against a database of copyrighted content with the aim of reducing violations.[43][44] On June 23, 2010, Viacom's lawsuit against Google was rejected in a summary judgment, with Judge Louis Stanton[45] stating that Google was protected by provisions of the Digital Millennium Copyright Act. Viacom announced its intention to appeal against the ruling. In August 2008, a U.S. court ruled in Lenz v. Universal Music Corp. that copyright holders cannot order the removal of an online file without first determining whether the posting reflected fair use of the material. The case involved Stephanie Lenz from Gallitzin, Pennsylvania, who had made a home video of her 13-month-old son dancing to Prince's song "Let's Go Crazy" and posted the 29-second video on YouTube.[46] PrivacyIn July 2008, Viacom won a court ruling requiring YouTube to hand over data detailing the viewing habits of every user who has watched videos on the site. The move led to concerns that the viewing habits of individual users could be identified through a combination of their IP addresses and login names. The decision was criticized by the Electronic Frontier Foundation, which called the court ruling "a set-back to privacy rights".[47] U.S. District Court Judge Louis Stanton dismissed the privacy concerns as "speculative", and ordered YouTube to hand over documents totalling around 12 terabytes of data. Judge Stanton rejected Viacom's request for YouTube to hand over the source code of its search engine system, saying that there was no evidence that YouTube treated videos infringing copyright differently.[48][49]Controversial contentYouTube has also faced criticism over the offensive content in some of its videos. The uploading of videos containing defamation, pornography and material encouraging criminal conduct is prohibited by YouTube's terms of service.[50] Controversial areas for videos have included conspiracy theories, religion, Holocaust denial, and the Hillsborough Disaster, in which 96 football fans from Liverpool were crushed to death in 1989.[51][52]YouTube relies on its users to flag the content of videos as inappropriate, and a YouTube employee will view a flagged video to determine whether it violates the site's terms of service.[50] However, this procedure has been criticized by the United Kingdom government: in July 2008 the Culture and Media Committee of the House of Commons of the United Kingdom stated that it was "unimpressed" with YouTube's system for policing its videos, and argued that "Proactive review of content should be standard practice for sites hosting user generated content." YouTube responded by stating: "We have strict rules on what's allowed, and a system that enables anyone who sees inappropriate content to report it to our 24/7 review team and have it dealt with promptly. We educate our community on the rules and include a direct link from every YouTube page to make this process as easy as possible for our users. Given the volume of content uploaded on our site, we think this is by far the most effective way to make sure that the tiny minority of videos that break the rules come down quickly."[53] BlockingMain article: Censorship of YouTube Several countries have blocked access to YouTube:
Video technologyPlaybackViewing YouTube videos on a personal computer requires the Adobe Flash Playerplug-in to be installed in the browser. The Adobe Flash Player plug-in is one of the most common pieces of software installed on personal computers and accounts for almost 75% of online video material.[70]In January 2010, YouTube launched an experimental version of the site that uses the built-in multimedia capabilities of web browsers supporting the HTML5Adobe Flash Playerplug-in to be installed.[71][72] The YouTube site has a page that allows supported browsers to opt in to the HTML5 trial. Only browsers that support HTML5 Video using the H.264 or WebM formats can play the videos, and not all videos on the site are available.[73][74] standard. This allows videos to be viewed without requiring or any other UploadingVideos uploaded to YouTube by standard account holders are limited to 15 minutes in duration. 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.[75][76] The ten minute limit was increased to fifteen minutes in July 2010.[77] Partner accounts are permitted to upload longer videos, subject to acceptance by YouTube.[78] File size is limited to 2 GB for uploads from YouTube web page, and to 20 GB if Java-based Advanced Uploader is used.YouTube accepts videos uploaded in most container formats, including .AVI, .MKV, .MOV, .MP4, DivX, .FLV, and .ogg and .ogv. These include video formats such as MPEG-4, MPEG, and .WMV. It also supports 3GP, allowing videos to be uploaded from legacy mobile phones.[79] Videos with progressive scanning or interlaced scanning can be uploaded, but for the best video quality, YouTube prefers interlaced videos to be deinterlaced prior to uploading. All the video formats on YouTube use progressive scanning.[80] Quality and codecsYouTube originally offered videos at only one quality level, displayed at a resolution of 320x240 pixels using the H.263 Sorenson Spark codec, with monoMP3 audio.[81] In June 2007, YouTube added an option to watch videos in 3GP[82] In March 2008, a high quality mode was added, which increased the resolution to 480x360 pixels[83] In November 2008 720p HD[84] With this new feature, YouTube began a switchover to H.264/MPEG-4 AVC as its default video codec. In November 2008, the YouTube player was also changed from a 4:3 aspect ratio to a widescreen 16:9. 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 4096x3072 pixels.[85][86] format on mobile phones. support was added. |
