JOHANNESBURG (AP) -- Facebook has opened its first office in Africa in a move aimed at cementing its business in the fast-growing region.
The world's largest social network says in a statement that the office in South Africa's largest city Johannesburg will help to grow the roughly 120 million users it already has in Africa, 80 percent of whom access the site via mobile devices.
Nicola Mendelsohn, Facebook's vice president for regions outside of North America, said 52 percent of the company's advertising revenue comes from outside of the U.S. and Canada.
South African digital strategist Toby Shapshak says sub-Saharan Africa is the world's second-fastest growing telecommunications market after Asia, underlining its importance to Facebook and rival networks.
Facebook already has offices in south and east Asia, according to its website.
