Although TikTok’s U.S. shopping rollout has gone slower than planned, the company continues to add features, with invited brands fielding an in-app checkout test.

After nine years as CEO of the world’s largest video-sharing platform, Susan Wojcicki announced last week that she was stepping down from YouTube, to be replaced by the company’s chief product officer Neal Mohan. The move comes after nearly 25 years of working for parent company Google, where she started as its first marketing manager (founders Larry Page and Sergey Brin famously set up Google’s early office space in Wojcicki’s Menlo Park garage). Wojcicki is known for leading the charge to acquire YouTube, co-creating Google Image Search and helping to launch AdSense, among numerous other accomplishments.

Another state has joined the federal fight to ban the short-form video app, with Virginia this month passing legislation prohibiting TikTok and WeChat from use on state government devices.
