SAN JOSE, Calif.—Facebook debuted an overhaul of its core social network on April 30, taking its first concrete steps to refashion itself into a private messaging and e-commerce company as it tries to move past scandals while tapping new revenue sources.
Chief Executive Mark Zuckerberg unveiled a fresh design for the world’s biggest social network that de-emphasized its News Feed. It also ditched the signature blue banner that has been on the app since its launch.
