Bilibili (stylized as bilibili, Chinese: 哔哩哔哩; pinyin: bīlībīlī) is a video sharing website themed around anime, manga, and game fandom based in China, where users can submit, view, and add commentary subtitles on videos. This website uses Adobe Flash Video and HTML5 technology to display user submitted videos hosted by third-party sources, while features a real-time overlaying subtitle system for interactive playback experience.
Inspired by similar video sharing websites Nico Nico Douga and AcFun, the founder of Bilibili, Xu Yi (Chinese: 徐逸; pinyin: xúyì), created a prototype website named Mikufans.cn in three days after college graduation. He launched the website on January 25, 2010 with the name Bilibili. Later in 2011, he founded a startup, Hangzhou Huandian Technology, to manage the development and operation of Bilibili.
Bilibili was ranked 1,991st by Alexa Global Ranking and it was ranked 232nd in China. (October 4, 2014)
Xu Yi was an AcFun user in 2009. He was unsatisfied by the instability of the service and decided to create an alternative out of fun. He spent three days and created a prototype website named Mikufans.cn as a fandom community of Hatsune Miku. As it grew, he reshaped the website to specialize in video sharing and launched it on January 14, 2010 with the name Bilibili (bilibili.us), which is the nickname of the protagonist Mikoto Misaka in the anime Toaru Majutsu no Index for her electric superpower.
In 2011, Bilibili's domain name bilibili.us was revoked because of the domain registrar enforcing .US restrictions. As a result, Bilibili switched to bilibili.tv on June 25, 2011. Afterwards, in late 2011, Xu Yi founded the startup, Hangzhou Huandian Technology (Chinese: 幻电; pinyin: huàndiàn; literally: "fantastic electricity") based in Hangzhou, Zhejiang, for better development and operation of Bilibili.
In April 2012, Bilibili obtained an agreement with Nico Nico Douga to webcast latest Chinese-subbed episodes of the newly airing anime Fate/Zero starting from April 7. However, this program was censored and ordered to stop after three episodes, for being reported as unauthorized operation of Internet audio-video broadcasting services. Its operating company Hangzhou Huandian Technology was administratively penalized and fined 10,000 yuan by local government.
In August 2012, Bilibili started to display logos on its homepage to indicate affiliation with the state-owned Shanghai Media Group and share the use of various content provider licenses in hope to avoid future legal risk. Meanwhile, anonymous visitors to bilibili.tv got redirected to a subdomain of Shanghai Media Group Broad Band subsidiary (bilibili.smgbb.cn).
Besides hosting video content, Bilibili's core feature is a real-time commentary subtitle system that displays user comments as streams of moving subtitles overlaid on the video playback screen, visually resembling a danmaku shooter game. These subtitles are called "danmaku" (literally "bullets"). Such subtitles are simultaneously broadcast to all viewers in real-time, creating a chat room experience in which users feel like watching and playing together with others. This system offers users various subtitle controls, including style, format, and movement. Users are also fond of creating translated and soramimi subtitles, or special effects with carefully formed subtitles. The site also offers a feature called "advanced subtitles", where users can use ECMAScript-based API to control video playback, dynamically change danmaku subtitles and draw shapes onto the screen. This functionality is only available with the video poster's permission.
Bilibili also has an API, enabling third-party developers to access website content including video lists, comments, "danmaku" subtitles, special topics and airing programs. The API service is open for signing up. It is rate-limited and requires developer keys for authentication.
Bilibili's operating company consists of a team of nine members all versed in the Japanese language and culture. Two are web developers, including Xu Yi himself, and the rest are website editors and moderators. Bilibili's service is completely free. Its main revenue comes from webpage advertisement and affiliate marketing.
Most content on Bilibili is free for anonymous viewing, while some is member-only to avoid censorship. Membership is required for submitting videos or comments. Bilibili limits membership availability to balance the quality of its user base and moderation capacity. Opportunity of signing up is available occasionally. Starting from March, 2013, the website is open for signing up with a limited number of invitation codes sent by existing users.
Challenges and Risks
Bilibili does not specify its video content sources, nor provide service to host or stream video, instead it relies on user-submitted posts which reference videos from third-party sources, such as Sina ，letv and Youku. Thus, it risks of being blocked from the sources as it grows large enough to become a burden. Even though its community has been resilient, it has difficulty in maintaining content availability and managing copyright infringement. Bilibili had success in negotiating with Japanese anime companies for licensed webcast, as mentioned above.
The Chinese government has stringent regulations and censorship on Internet services, particularly on Internet video services like Bilibili. Incomplete licenses or insufficient censorship compliance may be serious enough threats to shut down the entire operation of Bilibili if its legal defense is underprepared.
Bilibili has also established affiliated communities: Corari (Chinese: 协作乡; literally: "Hometown of Collaboration", currently offline), a collaboration project founding community; DrawYoo, a creative drawing community; The Ninth Channel, a support forum for Bilibili.
