Microsoft has watched a lot of the parts of their business that they have chased so far. They had expanded their business in many fields but now they are going for what Google is the best at, searching.
If you just ask someone, they would tell you that they are not searching but "googling" and it has become a phrase from a long time ago. This phrase was not even invented 2000 but by 2005, this phrase has become common and it is growing among the internet users.
The Chief Executive Officer of Microsoft said "I’m optimistic that we’re taking a big first step. And yet I want to be realistic. We’ve got to take a lot more steps."
