Remember when the first thing you did online was open Sina.com to read the news? What has it become today? This website’s journey is practically a history of the internet’s evolution.
Sina.com is like the “Transformer” of the internet world — its defining trait is constant evolution.
It started as an “information portal” providing news and search services. Now it has transformed into a “social platform” centered on “Weibo.” As of September 2022, the Weibo platform already had 584 million monthly active users in mainland China, demonstrating its massive social influence.
In the early days of internet adoption, users needed a clear starting point to explore the vast digital world. Sina.com seized this opportunity and quickly became the primary gateway for many.
In the early 2000s, the internet was still unfamiliar territory for most people. Sina.com, alongside Tencent, Sohu, and NetEase, was known as one of the “Big Four portals,” collectively defining the early Chinese internet landscape. It aggregated all kinds of information and services, acting as the “front door” to the online world.
For users at the time, opening the browser and typing Sina.com was equivalent to opening the door to the entire internet.
Users could read news, search information, and send emails here — meeting basic online needs. This one-stop service model made it a daily must-visit site for millions.
Sina.com’s original core was news. It aggregated content from media worldwide so users could quickly stay updated on current events. However, its ambitions went further. To build a richer content ecosystem, it once partnered with Google for search services and later developed its own search technology. This strategy enriched its portal functions and solidified its position as an information hub. From pure news aggregation, it gradually expanded into a comprehensive platform with diverse content.
With the arrival of Web 2.0, users no longer wanted only to consume information — they craved self-expression. The launch of Sina Blog was a crucial step in transforming into a content platform. This platform gave birth to mainland China’s first generation of online opinion leaders. Writer Han Han attracted massive readership with sharp commentary, becoming an iconic figure. Ordinary internet personalities like Sister Feng also rocketed to fame around 2005 through bold, confident blogging — becoming unique phenomena of early internet culture. The platform was not just a space for personal creation but a powerful amplifier of public opinion.

The success of blogs proved users’ strong desire for expression, but the market needed a faster, more real-time interaction format. Sina.com accurately captured this trend and launched “Sina Weibo” in 2009 — a decision that completely changed the company’s trajectory and reshaped the Chinese internet’s social landscape.
The core spirit of Web 2.0 is “user-generated content.” The birth of Sina Weibo was Sina.com’s key strategic move riding this wave. It adopted the microblogging model, allowing users to share thoughts and observations anytime, anywhere in 140 characters. This low-barrier design dramatically reduced content creation difficulty, turning ordinary people into information publishers. Weibo quickly became a platform for universal participation, ushering in a new era of real-time social interaction.
Weibo triggered a fundamental shift in user behavior. The purpose of going online changed from passively “reading news” to actively “posting on Weibo.” This was not just a platform change but a role change for users. To encourage this shift, Weibo invested heavily in product design.
Weibo’s design philosophy was to transform the platform from a content consumption venue into a vibrant content creation ecosystem.
It systematically empowered creators through a series of tools to motivate continuous content production. These tools include:
Additionally, the platform adopted card-style content blocks — not only improving visual experience but also making personalized content recommendations more effective. These designs collectively turned users from mere readers into active creators and disseminators.
As user base and influence exploded, Weibo gradually became a powerful brand independent of Sina.com’s portal. Its independence and further evolution are evident from these key milestones:
This listing was not only a capital success but also marked Weibo becoming financially and operationally independent. After independence, Weibo did not slow down — it accelerated feature evolution. It gradually introduced many new functions, transforming from a text-centric platform into a multimedia social square.
Investment in video paid off significantly. Financial reports show that focus on user-generated video directly drove significant active user growth in Q1 2017. This series of evolutions successfully transformed Weibo from a simple information feed into a comprehensive ecosystem integrating social, entertainment, and commerce.

Weibo’s evolution was not just Sina’s own transformation — it profoundly impacted the entire Chinese internet society. From an information platform, it became a powerful force shaping culture, guiding public opinion, and even changing industry ecosystems.
Weibo’s real-time nature and virality completely overturned traditional media’s news production process. Many major events were no longer first reported by journalists but initially exposed by ordinary users on Weibo.
Weibo turned everyone into a potential frontline “citizen journalist,” permanently rewriting the definition and dissemination path of news.
Some major news spread widely on Weibo before traditional media coverage, such as:
Facing this impact, traditional media institutions had to actively respond. They established official accounts on Weibo, using it as a key channel for news release and reader interaction. Many media began studying Weibo’s dissemination patterns to maintain influence in the new media ecology.
With its massive user base and unique product design, Weibo became one of mainland China’s most important public opinion arenas. Its Hot Search List (HSL) uses algorithms to instantly display the most discussed topics, directly influencing public attention.
The platform not only reflects public opinion but, to some extent, guides its direction through algorithms.
During major public events, Weibo became the core platform for people to express opinions, exchange information, and seek help. Taking the COVID-19 pandemic as an example, extensive key discussions unfolded on Weibo:
Government and experts could also monitor public opinion dynamics on Weibo to communicate more effectively with the public and formulate corresponding policies.
Weibo’s emergence also gave birth to organized, professionalized “fan economy.” Fans are no longer just admirers — they form tightly structured communities. These fan groups operate within Weibo’s “Super Topic” communities, even having internal divisions like copywriting, video production, and data management — functioning like mini companies.
Fans systematically “boost data” for idols online to increase their platform visibility and commercial value. This power extends beyond entertainment. For example, in health advocacy campaigns like “#National Mask Movement#,” celebrity idols effectively mobilized fans to forward and comment — greatly expanding the reach of public service information. This shows how Weibo transforms fan enthusiasm into powerful collective action.
Sina.com’s journey is like the evolution of an internet Transformer. From an entry portal meeting people’s need to “obtain information,” it successfully transformed into a social platform fulfilling the desire for “expression and connection.” This case reveals a core law of the internet era:
In the rapidly changing digital world, companies must dare to reinvent themselves. Only by riding the tide and continuously evolving can they stay ahead and remain invincible.
Sina.com was an early “information portal” mainly providing news and search services. Weibo is a “social platform” whose core function is letting users create and share short content for real-time interaction. The two represent Sina’s core businesses in different eras.
Weibo succeeded by riding the Web 2.0 wave. It lowered the content creation threshold to 140 characters, meeting users’ shift from “passively receiving information” to “actively expressing and sharing” — triggering a wave of universal participation.
Weibo’s real-time nature allowed every user to become a potential “citizen journalist.” Many major events were first exposed on Weibo, overturning traditional media’s reporting process. This forced media institutions to join Weibo, using it as a new channel for news release and reader interaction.
