Comscore: Microsoft tops time spent, 3.9B hours
According to Comscore’s time spent share study, Mirosoft experienced 43% YOY growth in the number of 
hours spent on its properties worldwide. At 3,920MM hours, MS tops the next runner up (Google) by over 56%. Given the nature of these two companies, this differential should not be too surprising. Google has many contacts at smaller durations, MS fewer contacts at longer engagements.
What is telling is the differential between MS and Yahoo!; about 242% more time spent. While Yahoo! is doing well in the US with 11.2% of total time spent vs. 8.6% for MS, Yahoo! is falling short globally, where the real growth will be seen. Combine the standing with the 14% decline to total hours on Yahoo! properties, and Yahoo! has a real problem to overcome. If Yahoo! is trading on engagement, this is going to be a problem. Yahoo! is going to need to give the global 
market place reason to care.
Not surprisingly, Facebook has seen phenomenal growth of 193% jumping from 474MM from 1,387MM hours.
