TikTok’s Chinese owner, ByteDance, finalized a deal on Thursday to set up a majority American-owned joint venture company to avoid a U.S. ban on the popular social media app used by more than 200 million Americans.

The deal is a milestone for the short video app after years of battles that began in August 2020, when President Donald Trump first tried unsuccessfully to ban the app over national security concerns.
