The impact of Facebook advertisements run by Cambridge Analytica on the 2016 US Presidential election has been overstated by CEO Alexander Nix, the media, and Christopher Wylie. Regression models are not yet too accurate, and the micro-targeted Facebook advertisement strategy was probably not used for the Trump campaign. While the Facebook advertisements run by Cambridge Analytica may not have had that much of an impact on the 2016 US election, this is just the beginning in the field of micro-targeted advertising through social media. With 2.3 billion monthly active users on Facebook, and 1.5 billion daily active users, Facebook is a tool unlike no other. The fact that your friends taking a quiz could extract your data on Facebook may have caught many people by surprise. Thus, as the number of users on Facebook continues to grow around the world, Facebook has the critical responsibility of clearly communicating privacy options to users. This is just the beginning of the use of micro-targeted Facebook advertisements, don’t be surprised in the future if you see political ads on Facebook that strongly resonate with you, before an election.

You seem to be putting up this barrier of conditions for you to watch it. It's just a film, not a major undertaking or commitment.

Wow, if politcal ads don't work, why do campaigns spend so much money on them?

Because its the only game in town, at least until they figure a way to actually control people's minds.
