Within a year of launch, how many users did Douyin have?

Within a year of launch, Douyin had 100 million users.

ByteDance launched Douyin in China in September 2016, and the app reached 100 million users within roughly its first year. That early milestone showed how quickly its short-video format and recommendation system were spreading among Chinese smartphone users. The same history notes that Douyin users were viewing more than one billion videos each day.

The figure refers to Douyin, the China-focused service, rather than a combined worldwide total for Douyin and TikTok. ByteDance later expanded internationally under the TikTok name, and TikTok eventually absorbed musical.ly’s international audience in 2018. Those later user counts are much larger and belong to a different stage of the company’s growth.

The 100-million milestone is especially notable because Douyin was still a young product. Its algorithmic feed reduced the need for users to search for creators manually, helping unfamiliar accounts reach large audiences. That discovery model became one of the defining features of TikTok worldwide.
