Popular video-sharing social network TikTok has officially gone dark in the United States, as a federal ban on the app comes into effect on January 19, 2025."We regret that a U.S. law banning TikTok will take effect on January 19 and force us to make our services temporarily unavailable," the company said in a pop-up message. "We're working to restore our service in the U.S. as soon as possible, and we appreciate your support. Please stay tuned."An immediate outcome of the ban means that existing users will no longer be able to access TikTok content, and new users won't be able to download the app from the official app stores for Android and iOS. Other apps from its parent company ByteDance, including CapCut, Lemon8, and Gauth, have become unavailable as well.
