Facebook makes some big changes to its advertisements

Facebook is making significant changes to the advertisements on its network, and will give users more control over which ads they see on its network.

The move comes as the company is also expanding its advertising program to include information that it pulls from sites users visit outside of its own network. Users will begin seeing notifications on their accounts about the changes starting June 11. "Today, we learn about your interests primarily from the things you do on Facebook, such as Pages you like," the company said. "Starting soon in the US, we will also include information from some of the websites and apps you use." Facebook does not currently show ads based on what users look at or buy outside of its own network -- though it does partner with some ad networks that do. This change means that Facebook's advertising system more closely mirrors those of its competitors, such as Google. That change is significant, if not particularly surprising as the 10-year-old service looks for ways to pull in more regular revenue.
