Microsoft has done poorly in anticipating and developing products for the internet and mobile devices. On the enterprise side the server and tools business has done well. Microsoft's Server And Tools business made operating profit of $8.2 billion in the year ending June 2013, up 13% from the prior year. Office 365 sold on a subscription basis to accomodate the shift to cloud computing, and other cloud products are expected to make up for decline in Windows revenues with decline in PC sales. Satya Nadella, who ran the Server and Tools business from 2011 till he was shifted to head the cloud computing effort in the reorganization of 2013, is a candidate for the CEO position.
