Facebook rearranging notification buttons to highlight video

The shift announced Wednesday is part of Facebook's effort to turn its live video feature into a marquee attraction as more people use their smartphones to record and share snippets of their lives.

The update underscores Facebook's commitment to a live video option introduced last year to compete against Periscope, a similar service run by its smaller rival, Twitter.

Since its debut, Facebook's live video has been used to provide glimpses of parties and vacations as they happen.
