Really depends on what you are selling as to whether Facebook advertising will work. Not difficult with some simple demographic research.
Think young, hip crowd who don't want their father's automobiles. Established businesses trying to market to a younger generation is a difficult and expensive endeavor. Pepsi was able to pull it off well, I guess.
Sure, there are all ages and kinds on Facebook, but the ones who have a live wire on the mobile and post every 5 seconds are younger and have more time and are in a stage of life where fitting in with peers is important.
You can't market with reputation, "in business since 1953", family items, luxury goods.
