In November 1998, SRSNet (Stone Rich Sight Information Technology Ltd), the most visited internet portal site in China, established by Wang Zhidong [zh] and Wang Yan in 1996, merged with Sinanet, a web site for American Chinese community, created in California by Hurst Lin, Ben Tsiang [zh], and Jack Hong in 1995.

After the merger, Sina maintained its dominant position as the most visited portal site in Mainland China over its major rivals Sohu and NetEase,[6] two other web-based companies in China. Especially through its fast, continuous, and comprehensive online news services covering a vast range of worldwide events, such as the NATO Bombing of the Chinese embassy in Belgrade in 1999.[7][6]

Sina was the first to be approved for listing on the Nasdaq National market on 13 April 2000, through a variable interest entity (VIE) based in the Cayman Islands, followed by Netease and Sohu in June and July respectively. It succeeded in raising US$68,000,000 before Nasdaq plummeted in May 2000. In July 2000, Sina was the official website for on-line coverage of the 2000 Summer Olympics in Sydney as selected by the government and the Chinese Olympic committee (Xin, 2002).[8][6]

The Cyberspace Administration of China reprimanded Sina in 2015, accusing the online portal of having "distorted news facts, violated morality and engaged in media hype".[9] On 16 April 2018, the CAC launched an investigation into the news portal for alleged inclinations to factual errors, and failure to curtail vulgar and explicit content.[10][6]

In August 2019, Sina Corp's Game Studio, Sina Games was sued by Blizzard Entertainment on a claim that their game Glorious Saga is a blatant rip-off of the long running Warcraft games and related products.[11][12][13][6]

Local content[edit]

To provide tailored internet services for local people, Sina has been conducting quantitative and qualitative marketing researches, including demographic research, psychograph, etc., on target audience in specific regions. Internationalized services have a common layout which consists of sections like news, information, infotainment and email services with localized content.[citation needed]

Localization involves political censorship. As with all internet content providers operating within mainland China, the web pages which are geared toward mainland China audiences have internet censors controlling the discussion for sensitive political content. In addition, the news from sina comes from local newspapers, which in the case of mainland China are themselves subject to censorship by the government. This censorship does not extend to pages and forums which are not intended for audiences within mainland China.[citation needed]
