<p>Over 1 million users have signed up for Microsoft's Office 365 Home Premium service, Microsoft said Wednesday, a milestone that the company touted as a success for the subscription service.</p><p>Microsoft also said that the new Office (presumably including both Office 365 and Office 2013) "is officially the best-selling Office edition yet, with more than one sold every second on average since it launched." That works out to 120 days since it launched on Jan. 29, or 10,368,000 seconds, presumably meaning that Microsoft has sold more than 10 million Office licenses.</p><p>However, the company didn't say how many users had signed up for the corresponding Office 365 versions for business or education. In March, the company said that more than 1 million workers are now using Office 365 in federal, state, and local government agencies.</p><p>Update: When asked for clarification, a Microsoft spokeswoman responded with the following statement: "Office 365 is the fastest growing business in Microsoft history; it's a one billion dollar run-rate business and last quarter the number of paid Office 365 seats increased 5x year over year."Office 365</p><p><a href="http://www.pcworld.com/article/2040088/microsoft-signs-up-1-million-office-365-home-subscribers.html">Keep reading...</a></p>
