Sina

Sina.com is the international-facing domain of Sina Corporation, a foundational Chinese internet company. Founded in 1998, Sina launched as a comprehensive web portal that quickly became a daily destination for millions of Chinese-speaking users worldwide. The domain sina.com was registered on September 16, 1998, and has been continuously operated ever since, making it one of the oldest active Chinese internet domains. Sina's core offerings include Sina News, a leading online news platform covering politics, business, technology, and lifestyle; Sina Mail, a free web-based email service; and Sina Finance, which provides real-time stock quotes, market data, and financial journalism. The company also pioneered social media with Sina Weibo (launched 2009), which revolutionized microblogging in China and later became an independent entity. Despite the spin-off, Sina's portal remains a major traffic driver, with a global rank of #4978 according to available data. The domain's robust DNS and mail infrastructure supports millions of users daily. Over its 27-year history, Sina has navigated China's rapidly evolving internet landscape, adapting from desktop to mobile and competing with portals like Sohu, NetEase, and Tencent's QQ. While direct automated access is not available—likely due to regional access controls—the domain's longevity and consistent traffic attest to its significance. Sina.com's owner, Sina Corporation, has been a publicly traded entity (NASDAQ: SINA) until its privatization in 2020, reflecting its corporate maturity. Today, Sina continues to serve as a vital information hub, particularly for news and financial data, and remains a symbol of the early Chinese internet era. Its enduring presence underscores its role as a cornerstone of China's digital ecosystem.
