TikTok is looking to significantly expand its e-commerce platform. This year, the short video app’s business with advertising links for goods during live broadcasts is expected to quadruple to as much as $20 billion, Bloomberg reported, citing people familiar with the matter. The app, which is particularly popular with young people, is increasingly targeting markets such as Indonesia and working to expand its sales in the U.S. and Europe. TikTok and its Chinese parent ByteDance are currently facing criticism around the world for their closeness to the Chinese government, privacy concerns and lobbying.
