Google has answers for pretty much everything. If you are one of the 4.3 billion internet users, Google likely knows a lot about you too.
The data of personal information, preferences, likes/dislikes it collects from its browsers and services is mined to create ‘targeted advertising’ from other businesses, which is where Google makes most of its money, to the tune of billions of dollars. The tech titan is capitalizing on ‘network effects’ i.e. each additional user is making the company more valuable.
