Why has Facebook started putting advertisments all over its homepage/newsfeed?

I find it frustrating as well. They have so many because companie pay them to show ads. They make extra money if someone clicks on the add or the website that they are advertising. They put it all over the home and newsfeed pages because those pages are the most visited by users, so it's more likely that someone will click on the pages that are most visited. They do this in an attempt to make more money.
