Catch and Release Online Viewers

So I noticed today that a lot of companies that advertise on Youtube and Facebook (two sites that are pretty cutting-edge on the internet right now, you may not have heard of them) don't direct you to their own websites. Instead, they take you to that company's own profile page. Since the idea is just to get the product or brand name in your head, there's no sense in taking you away from what you were doing in the first place. If you're going to spend some time on Facebook, but you click an ad and it takes you away from Facebook, you'll exit that window right away and go back to what you were doing. However, it it takes you to a Facebook profile, you might look around for a bit. That's what you were going to do anyway.
