ABC's Muir to do brief Facebook newscast

NEW YORK -- ABC's "World News Tonight" anchor David Muir will do a one-minute newscast each weekday for Facebook, touching on the day's top stories and trending topics online.

The "Facecast" will usually be posted in the early afternoon, and started Monday.

ABC said Facebook users will see the report in their news stream if they have "liked" ''World News Tonight," or else will be able to find it on the newscast's Facebook page.

ABC said it was the first newscast created specifically for social media by an evening news anchor.

Called "Facecast: The One Thing," the brief newscast will feature video and updates on breaking news, the economy, politics and sports.
