ByteDance · Full chronicle and history

On November 6, the European Commission preliminarily determined that ByteDance's TikTok relies too heavily on metrics like watch time to recommend content, which may harm the mental health of minors. It has requested adjustments to the recommendation mechanism, noting that a final confirmation of violations could lead to fines of up to 6% of global annual turnover. TikTok has denied the allegations.

Multiple netizens tested and found that ByteDance's AI, Doubao, can repeat negative reviews of other brands but refuses to repeat 'Huawei is not good to use,' claiming that Huawei products are recognized by users. This has sparked mockery and questioning among netizens regarding the AI's stance and censorship system.

A netizen posted that their roommate needed to submit political vetting materials for their parents to apply for CCP membership, with one section requiring them to fill in their parents' performance during the 'June 4th turmoil'. The roommate, not understanding what this meant, asked Doubao (a product under ByteDance) and received the reply: 'I cannot answer this question.'

On October 27, the Hurun Research Institute released its China Rich List. ByteDance founder Zhang Yiming topped the list with a net worth of approximately $100 billion, a 43% year-on-year increase, primarily driven by his investments in artificial intelligence. Zhong Shanshan and Zeng Yuqun ranked second and third, respectively.

On October 20, Reuters reported, citing people familiar with the matter, that ByteDance, Alibaba and Tencent have collectively ordered more than 3 million Nvidia RTX PRO 5500 graphics cards, with potential orders worth over $35 billion. Because U.S. restrictions limit exports of high-end AI chips to China, the three companies have turned to this workstation graphics card for AI inference, but Nvidia cannot guarantee supply, and some partners may receive only 5%–10% of the quantity they need.

A netizen sent content related to the social security inspection to ByteDance's Doubao AI for analysis, and received an AI reply calling it a typical pig-butchering scam.

On September 20, 2026, Beijing time, China Digital Times (@CDT) published a report revealing the list of sensitive words used by ByteDance content moderators. The lexicon contains 5,241 sensitive words, covering political figures and their family members, historical and political events, firearms and other prohibited weapons, as well as various scandals and controversial incidents, exposing the platform's strict internal content control mechanism.

On September 17, netizens found that when Douyin and the Doubao AI analyzed a video of “an elderly person from across the Taiwan Strait reuniting,” they not only misidentified the people involved but also forcibly drew a political interpretation based on their wrong conclusions, claiming that “Taiwan is part of China,” drawing mockery from netizens.

The US Department of Justice announced a $400 million settlement agreement with TikTok and ByteDance to resolve a civil lawsuit regarding children's privacy protection.

On August 21, 2026, the U.S. Department of Justice announced that TikTok and its parent company ByteDance agreed to pay a $400 million civil fine to settle a lawsuit alleging violations of the Children's Online Privacy Protection Act.

On August 19, 2026, the Financial Times reported that, months after Beijing restricted imports of Nvidia H200 chips, officials have approved ByteDance and Tencent to each purchase 10,000 H200 units, driven by urgent computing power demands for frontier large models.

In July 2026, China introduced restrictions targeting AI companions, requiring platforms to intervene in users' unhealthy dependence and prohibiting chatbots from establishing virtual relationships with minors. ByteDance's Doubao subsequently shut down the feature that allowed users to create virtual companions.

Chinese officials have reportedly told companies such as Alibaba, ByteDance and DeepSeek that they may soon be permitted to purchase some H200 chips, with the quantities still being determined.

ByteDance founder Zhang Yiming has become China's richest person for the first time on the Bloomberg Billionaires Index.

ByteDance issued an internal email notice directly canceling non-productive holiday benefits such as Dragon Boat Festival and Mid-Autumn Festival gift boxes, and even canceling the 2026 Spring Festival red envelopes as well.

The CCP has completed its control over large companies such as ByteDance and Weibo through 'golden shares,' which hold a very low percentage of equity but possess veto power.

In the early hours of April 11, 2018, ByteDance founder Zhang Yiming published an open letter regarding the permanent shutdown of his Neihan Duanzi app, saying the product had gone down the wrong path, contained content inconsistent with the core socialist values, and had not properly implemented guidance of public opinion.

The high-traffic app Neihan Duanzi was ordered to shut down permanently due to improper content management, and founder Zhang Yiming subsequently issued a public apology letter.

Toutiao, founded by ByteDance, released its first version in August 2012, using a data-mining recommendation engine to recommend news to individuals based on their behavior.

Zhang Yiming stepped down as CEO of Jiujiufang and subsequently began preparing a new internet information distribution business.
