China tech crackdown: Alibaba, Tencent, ByteDance posts weaker ad revenue growth in 2021, report says
- Growth of China’s internet advertising market declined last year, as regulatory pressure on tech firms increased
- Antitrust investigations and a ban on off-campus tutoring services dampened online advertising business on the mainland

Growth in advertising revenue at China’s three biggest technology companies – Alibaba Group Holding, Tencent Holdings, and ByteDance – slowed in 2021 amid Beijing’s regulatory clampdown on the internet industry, according to new research.
Top-ranked Alibaba, owner of the South China Morning Post and the subject of a major antitrust investigation last year, saw its advertising market share among Chinese internet companies decline to 29 per cent, from 30 per cent a year ago, according to a report published by research firm Interactive Marketing Lab Zhongguancun, accounting and consulting firm PwC, and other organisations.
The advertising business of second-ranked ByteDance, owner of short video platforms TikTok and Douyin, rose to 21 per cent from 19 per cent in 2020. Social media and video gaming giant Tencent, ranked third, retained a 15 per cent share last year.
Overall, the growth of China’s internet advertising market dropped to 9.3 per cent from 13.8 per cent a year ago, according to the report.
The past year was challenging for China’s tech industry, as authorities moved to rein in the country’s powerful Big Tech companies after years of relatively lax governance.
