As a social media marketer, I can tell you that facebook is by far the best place to advertise when you want to go after a specific demographic. You can use the ads to target very very specific niches that are otherwise unreachable. With Google, people are coming to you, they know what they are searching for and your ads are designed to appeal to that. The problem with search targeted ads though, is that you can't target people who don't know your product exists. Facebook's CPC(cost-per-click) and CPM(cost-per-thousand impressions) are way lower as well, especially for demographics that google AdWords would charge you through he nose for. And as a benefit to good marketers, the Facebook advertising platform rewards you with lower costs the more successful your ads are. You can create ads based on the interests you enter into your profile, city, age, sex, birthday, etc. A lot of companies are starting to take notice of the power of these ads, which is causing the advertising prices to rise (it's a bidding system), which in turn will increase FB's profit. Facebook isn't going to go away anytime soon, people will always need a way to map out their connections, and Facebook is the de facto online identity for most people. I don't see Facebook being dethroned anytime soon, maybe disrupted a bit, by the likes of twitter or foursquare, but the core services of FB are something that will always be in demand.
