Q4 was a strong finish to the year with revenue of $1.29 billion, up 28% year over year, reflecting better-than-expected performance across all major products and geographies. Strong revenue performance also drove better-than-expected profitability, with GAAP operating income of $252 million and GAAP operating margin of 20%.

Average monetizable DAU (mDAU) reached 192 million, up 27% year over year and up 5 million quarter over quarter, driven by global conversation around current events and ongoing product improvements.

We made significant progress on our brand and direct response products in advance of the recent relaunch of our Mobile Application Promotion (MAP) offering. New ad formats, stronger attribution, and improved targeting resulted in a 31% year-over-year increase in total ad revenue and greater than 50% year-over-year growth in MAP revenue in Q4.
