In what comes as little surprise to those who have been watching Facebook’s general trend towards advertising, Facebook will announce a full fledged Mobile Ad network at its F8 developer conference in San Francisco at the end of this month. The goal, of course, is to get publishers and developers to leverage the social network’s giant database of user information for the purpose of expanding ad reach more broadly. Now, Facebook will be able to make money off of its users beyond the confines of the Facebook platform. Facebook’s been trying out different models for different types of ad networks, but with $1.24 billion in mobile ads generated in the last three months of 2013, it’s clear that Facebook understands that it’s going to need this network to move forward financially. It’s also going to allow mobile advertisers to market to mobile phone users in an extremely granular fashion, in the very near future.
