TikTok

ByteDance's app built its reach on a recommendation feed rather than on who you follow, so a first post can find an audience and a large following guarantees nothing on its own. Clips run from a few seconds to 10 minutes. The culture rewards fast openings, on-screen text and trends picked up within days of them appearing. Most YouTube creators treat the app as a second home for vertical work rather than a channel to build from scratch. Its ownership and availability have been politically contested in several countries, most publicly the United States, which makes it a real planning risk for anyone whose income depends on one app.
