Facebook tests TikTok-style, full-screen video first experience

Facebook plans a reimagined, full-screen video-first experience and will test it later this year in video-loving markets, with a US rollout possible next year, in a bid to curb user loss as rivals like TikTok grow (TikTok surpassed 1 billion monthly users). Meta has already deployed Reels to compete and is expanding experiments to keep users from migrating to shorter-form video apps.
