This document summarizes a study into the effectiveness of advertising to millennials on the Facebook mobile app. The study found that millennials tend to view mobile ads on Facebook as hindering their social media experience and consciously ignore them, defeating the purpose of the ads. The study conducted a survey using ads for the mobile game Game of War to understand millennials' reactions. It found that millennials respond better to more subtle ads following the "weak theory of advertising" rather than overtly persuasive ads based on the "strong theory of advertising." For mobile ads on Facebook to be effective for millennials, they need to slowly increase awareness over time through unobtrusive reminders rather than sales pitches.
