ByteDance Time: How a Top-50 Usage Share Turned Into a Public Data Fight

By Sarah Chen | MyTechDailyNews

A debate over whether 'ByteDance time' exists inside China's internet has moved from market chatter into a public exchange between Qin Shuo and Douyin Group Vice President Li Liang. Recently, the argument focused on one widely quoted usage statistic: the share held by ByteDance apps in the Top 50 mobile internet applications, and whether that share can be read as the share of all online time.

The starting claim: ByteDance apps are dominant in the Top 50

Qin Shuo wrote on Qin Shuo Friends Circle that Nomura Securities cited QuestMobile data to say that, in August 2026, ByteDance apps accounted for 41.8% of usage time among China's mobile internet Top 50 apps, while Tencent apps accounted for 28.6%, a gap of about 13.2 percentage points.

Qin Shuo's broader point is that China's mobile internet time is made up of many parts: ByteDance time, Tencent time, Taotian time, Pinduoduo time, Xiaohongshu time, Meituan time and others. In his framing, ByteDance apps already hold more than 40% of total user usage time, and the trend is significant, so the phrase 'China internet's ByteDance time' describes that visible shift.

The rebuttal: the data shows something narrower

Today, Li Liang posted on Weibo that Qin Shuo's analysis contained several basic errors of common sense. His first objection concerned the legal and economic threshold of market dominance. Li Liang noted that Qin Shuo mentioned Article 24 of the Anti-Monopoly Law, under which one operator can be presumed to have market dominance when its share reaches one-half, but the cited figure was 41.8%, still below one-half.

Li Liang also said that Tencent's instant messaging is the exception because its network relationship moat keeps it in a dominant position, while other products are more like flags changing on the city wall.

Li Liang wrote: 'I guess Japan Nomura's data was given to Mr. Qin Shuo by others, and Mr. Qin Shuo did not read it carefully. Nomura measured the time allocation inside the Top 50 apps. The calculation was: the sum of monthly total usage time of a group's apps included in the Top 50 divided by the monthly total usage time of all Top 50 apps. It did not count long-tail apps, and it did not count PC online time; many people need to stay online at work, and some WeChat and office software are kept open.'

The core gap: Top 50 time is not the whole internet time

Li Liang argued that this is not China internet's total usage time, but China internet's mobile-end Top 50 usage time. He noted that Nomura Securities' report itself labeled the measurement as a tracking estimate. He then said it was not rigorous to infer a conclusive 'China internet ByteDance time' from that narrower denominator, and that it was not excessive to say the original conclusion was not serious enough, because it did not fit his previous style as a real scholar.

The counter-test: if investment counts, the logic changes

Li Liang wrote: 'Nomura's statistical method is also worth discussing. If apps controlled through equity investment are counted, total usage time should belong to Tencent apps; then, according to Mr. Qin Shuo's logic, China's internet should be Tencent time, and it has already continued for 20 years and will continue. Mr. Qin Shuo, do you not feel absurd?'

Why the argument became personal

At the end, Li Liang used a sarcastic closing quote. He said he did not remember which celebrity had said it: 'We know why you are talking nonsense, you know why you are talking nonsense, you know that we know why you are talking nonsense, we know that you know that we know why you are talking nonsense, but you are still talking nonsense.'

What ordinary readers should take away

For everyday tech readers, the disagreement is not mainly about whether ByteDance apps are popular. The reported Top 50 share suggests that they were very prominent in that list. The debate is about whether that list can be expanded into a final judgment about China's entire internet time. Li Liang's criticism focused on the denominator: who was counted, which apps, which devices, and which assumptions about ownership.

Checklist before accepting a headline share number

• Ask what universe is being measured: all internet time, mobile internet time, or only Top 50 apps.
• Ask who provided the data and how the group share is calculated.
• Check whether long-tail apps are excluded.
• Check whether PC online time is included.
• Check whether the report describes the number as a tracking estimate.
• Check whether ownership through investment changes the group label.

Common misunderstandings

1. Seeing 41.8% in the Top 50 and treating it as the whole internet.
2. Treating a list share as proof of market dominance under Article 24 when the share is below one-half.
3. Assuming a group label automatically includes every app connected to that group.
4. Ignoring always-on messaging and office tools in WeChat and other PC or mobile contexts.

FAQ

Does the argument say ByteDance apps are not big?

No. The fact anchor from the debate is that QuestMobile data cited by Nomura Securities showed ByteDance apps at 41.8% of usage time in the Top 50, while Tencent apps were at 28.6%.

What did Li Liang object to?

He objected to the leap from a Top 50 mobile app measurement to a conclusive statement about China internet's ByteDance time. He said the data did not cover long-tail apps, PC time, or all always-on usage, and he cited the report's tracking estimate wording.

What is the practical lesson?

Read percentages as answers to a specific question. If the question is 'Which apps dominate the Top 50,' the number may support that. If the question is 'How is all China internet time divided,' the answer may require more data.

Action advice

When a platform claim sounds like a verdict, first identify the denominator. For product, market, and policy readers, the safer conclusion is to describe the measured environment precisely: a Top 50 mobile app usage share, a group share inside a tracking estimate, or a broader internet-time claim. That keeps the public debate factual instead of turning one number into a sweeping label.
