Instagram's Global Rollout of One-Way Broadcast Channels.

Instagram's broadcast channels, a one-way messaging feature, will be available globally, allowing users to send messages to their followers, who can react to them and vote in polls, but can't respond directly. Creators can post images, videos, and audio clips, and invite others to join their channel as a collaborator. Meta plans to bring channels to Facebook and Messenger as well, and is developing a text-based "decentralized social network" to rival Twitter.
