Facebook disclosed in March that about 1.65 billion people now use the site each month. According to the International Telecommunication Union, a total of 3.17 billion people used the Internet globally in 2015.
To date, Facebook has only showed ads across its Audience Network to Facebook users, targeted based on information the company has collected about its users’ tastes and behaviors. Now Facebook plans to collect information about all Internet users, through “like” buttons and other pieces of code present on Web pages across the Internet. It will then use the information it collects to target ads to non-Facebook users.
