As of this posting, 18,000 people are watching and are commenting live on the episode. It's an interesting experiment for the network which premiered the series Sunday, May 22. AMC skipped out on airing a new episode over Memorial Day Weekend so the second episode of the series won't premiere until Sunday, June 5.
It's also something I've never seen another network or movie studio do. For AMC, a subsequent Facebook live stream of "Preacher" could help remind viewers to tune in to the second episode.
For other networks and movie studios, Facebook Live could present an opportunity to debut teasers or trailers exclusively to the social network. Or, who knows? Maybe this is the future of TV.
