Meta’s “broadcast channels,” previously available for Instagram and WhatsApp, will be coming to Facebook and Messenger “in the coming weeks,” according to Meta. CEO Mark Zuckerberg also shared the news in a post from his personal Facebook account. Broadcast channels function a bit like giant but limited group chats. A creator can invite their followers and then blast things like voice notes, polls, text posts, videos, and photos to anyone who joins. Channel members receive notifications whenever the creator drops content. Specifically, these channels will be available for Pages on Facebook, and they’re in testing now. Those who manage the official page for a celebrity or a company, for example, will be able to start a channel directly from the page. Those who wish to join a broadcast channel will be able to do so directly from any specific page. Broadcast channels have proven to be a handy thing on Instagram, where they’ve been since February of this year.
