Facebook Unveils Watch

Facbook introduces Watch, a video tab that's a bid to grab viewers from TV and YouTube. According to Facebook, it will be a new home for original video content produced exclusively for it by partners, who will earn 55 percent of ad break revenue while Facebook keeps 45 percent. The Watch tab and several dozen original shows will start rolling out to a small group of US users and soon to others on mobile, desktop, and Facebook's TV apps.
