Ad sales at Facebook rose 63% to $6.24 billion, accelerating from a 57% rise in the first quarter and fourth quarter. Around 84% of second-quarter ad revenue came from mobile. Facebook warned that ad growth will slow in the third and fourth quarter as it deals with tougher annual comparisons.

(AAP holds Facebook in its portfolio). "The balance is key in this business in order to keep both users and advertisers happy. Facebook has put together a team that can cater to both sides of the spectrum. What a glorious time to be a Facebook shareholder, indeed."
