Machinima filmed in Second Life
Machinima (/məˈʃnmə/ or /məˈʃɪnmə/) is the use of real-time computer graphics engines to create a cinematic production. Most often video games are used to generate the computer animation. Machinima-based artists, sometimes calledmachinimists or machinimators, are often fan laborers, by virtue of their re-use of copyrighted materials (see below). Machinima offers to provide an archive of gaming performance and access to the look and feel of software and hardware that may already have become unavailable or even obsolete; for game studies, "machinima’s gestures grant access to gaming’s historical conditions of possibility and how machinima offers links to a comparative horizon that informs, changes, and fully participates in videogame culture."[1]
The practice of using graphics engines from video games arose from the animated software introductions of the 1980sdemosceneDisney Interactive Studios1992 video game Stunt Island, and 1990s recordings of gameplay in first-person shooter (FPS) video games, such as id Software's Doom and Quake. Originally, these recordings documented speedruns—attempts to complete a level as quickly as possible—and multiplayer matches. The addition of storylines to these films created "Quake movies". The more general term machinima, a portmanteau of machine cinema, arose when the concept spread beyond the Quake series to other games and software. After this generalization, machinima appeared in mainstream media, including television series and advertisements.
Machinima has advantages and disadvantages when compared to other styles of filmmaking. Its relative simplicity over traditional frame-based animation limits control and range of expression. Its real-time nature favors speed, cost saving, and flexibility over the higher quality of pre-rendered computer animation. Virtual acting is less expensive, dangerous, and physically restricted than live action. Machinima can be filmed by relying on in-game artificial intelligence (AI) or by controlling characters and cameras throughdigital puppetry. Scenes can be precisely scripted, and can be manipulated during post-production using video editing techniques. Editing, custom software, and creative cinematography may address technical limitations. Game companies have provided software for and have encouraged machinima, but the widespread use of digital assets from copyrighted games has resulted in complex, unresolved legal issues.
Machinima productions can remain close to their gaming roots and feature stunts or other portrayals of gameplay. Popular genres include dance videos, comedy, and drama. Alternatively, some filmmakers attempt to stretch the boundaries of the rendering engines or to mask the original 3-D context. The Academy of Machinima Arts & Sciences(AMAS), a non-profit organization dedicated to promoting machinima, recognizes exemplary productions through Mackie awards given at its annual Machinima Film Festival. Some general film festivals accept machinima, and game companies, such as Epic GamesBlizzard Entertainment and Jagex, have sponsored contests involving it.

In November 2006, it was bought by Google for US$1.65 billion.[4] YouTube now operates as one of Google's subsidiaries.[5] The site allows users to upload, view, rate, share, and comment on videos, and it makes use of WebMH.264/MPEG-4 AVC, and Adobe Flash Video technology to display a wide variety of user-generated andcorporate media videos. Available content includes video clipsTV show clips, music videos, audio recordings, movie trailers, and other content such as video blogging, short original videos, and educational videos.
Most of the content on YouTube has been uploaded by individuals, but media corporations including CBS, the BBCVevoHulu, and other organizations offer some of their material via YouTube, as part of the YouTube partnership program.[6] Unregistered users can watch videos, and registered users are permitted to upload an unlimited number of videos and add comments to videos. Videos deemed potentially offensive are available only to registered users affirming themselves to be at least 18 years old. As of July 2016, the website was ranked as the second most popular site by Alexa Internet, a web traffic analysis company.[3]
YouTube earns advertising revenue from Google AdSense, a program which targets ads according to site content and audience.

Google is an American multinational technology company specializing in Internet-related services and products that include online advertising technologies, searchcloud computing, and software.[7] Most of its profits are derived from AdWords, an online advertising service that places advertising near the list of search results.[8][9]
Google was founded by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University, California. Together, they own about 14 percent of its shares and control 56 percent of the stockholder voting power through supervoting stock. They incorporated Google as a privately held company on September 4, 1998. An initial public offering (IPO) took place on August 19, 2004, and Google moved to its new headquarters in Mountain View, California, nicknamed the Googleplex.[10]
In August 2015, Google announced plans to reorganize its interests as a holding company called Alphabet Inc. When this restructuring took place on October 2, 2015, Google became Alphabet's leading subsidiary, as well as the parent for Google's Internet interests.[11][12][13][14][15]
Rapid growth since incorporation has triggered a chain of products, acquisitions and partnerships beyond Google's core search engine (Google Search). It offers online productivity software (Google Docs) including email (Gmail), a cloud storage service (Google Drive) and a social networking service (Google+). Desktop products include applications for web browsing (Google Chrome), organizing and editing photos (Google Photos), and instant messaging and video chat (Hangouts). The company leads the development of the Android mobile operating system and the browser-only Chrome OS[16] for a class of netbooks known asChromebooks and desktop PCs known as Chromeboxes. Google has moved increasingly into communications hardware, partnering with major electronics manufacturers[17] in the production of its "high-quality low-cost"[18] Nexus devices.[19] In 2012, a fiber-optic infrastructure was installed in Kansas City to facilitate a Google Fiber broadband service.[20]
Google has been estimated to run more than one million servers in data centers around the world (as of 2007).[21] It processes over one billion search requests[22] and about 24 petabytes of user-generated data each day (as of 2009).[23][24][25][26] In December 2013,Alexa listed Google.com as the most visited website in the world. Numerous Google sites in other languages figure in the top one hundred, as do several other Google-owned sites such as YouTube and Blogger.[27]
Google's mission statement from the outset was "to organize the world's information and make it universally accessible and useful," and its unofficial slogan was "Don't be evil".[28][29][30] In October 2015, the motto was replaced in the Alphabet corporate code of conduct by the phrase: "Do the right thing".[31] Google's commitment to such robust idealism has been increasingly been called into doubt due to a number of actions and behaviours which appear to contradict this.[32][33]
