Facebook Inc. (Nasdaq: FB) reported robust Q2 2015 earnings Wednesday after the close.

Leading up to the results, anticipation was running high for FB to finally cross the $100 per share milestone. The social networking trailblazer has been flirting with triple digits since reaching an all-time high of $99.24 on July 21. Year to date, shares have climbed 23.15%.
