And it’s not even the best scenario for companies either. In Q4 of 2015 Facebook brought in $5.9 billion in revenue with 1.59 billion active users/month. That’s roughly $1.23 of revenue/user/month. If, in the same quarter, Facebook moved away from ads and instead charged each active user just $1.50 a month for the service, their Q4 2015 revenue would have increased by $1.2 billion dollars, from $5.9 billion to $7.1 billion.
