On September 3, 2013, Microsoft agreed to buy Nokia's mobile unit for $7 billion. Also in 2013, Amy Hood became the CFO of Microsoft. The Alliance for Affordable Internet (A4AI) was launched in October 2013 and Microsoft was part of the coalition of public and private organizations that also included Facebook, Intel and Google. Led by World Wide Web inventor Tim Berners-Lee, the A4AI seeks to make Internet access more affordable so that access is broadened in the developing world, where only 31% of people are online. Google will help to decrease Internet access prices so that they fall below the UN Broadband Commission's worldwide target of 5% of monthly income. In line with the maturing PC business, in July 2013, Microsoft announced that it would reorganize the business into four new business divisions by function: Operating System, Apps, Cloud, and Devices. All previous divisions were diluted into new divisions without any workforce cuts.
