Facebook: Breaking Up Facebook Is Not the Answer

In messaging, we’re not even the leader in the top three markets — China, Japan and, by our estimate, the United States — where we compete with Apple’s iMessage, WeChat, Line and Microsoft’s Skype. Almost all of our revenue comes from digital advertising, and most estimates say Facebook’s share is about 20 percent of the United States online ad market, which means 80 percent of all digital ads happen off our platforms. In Facebook’s case, our size has not only brought innovation, it has also allowed us to make a huge investment in protecting the safety and security of our services.
