Facebook's Finally Turning on the AD machine

Having a cousins wedding coming up in October, I started looking for flights to LA on Orbitz. After finding a good deal, I bought a ticket and called it a day. Going on Facebook about 20 minutes later there was an Advertisement I had never seen before. Looking for a hotel in LA, go to orbitz.com. Seems like they are turning the ad machine on, got to make up that 50 billion lost somehow
