We started 2016 off well. 1.65 billion people now use Facebook every month and 1.09 billion people use Facebook every day. In recent weeks, we're also consistently seeing more than 1 billion people using Facebook on mobile every day.
We're also pleased with our business results. Total revenue this quarter grew by 52% year on year to $5.4 billion, and advertising revenue grew by 57% to $5.2 billion. I'll have more to say about these results in a minute, but first I want to talk about a proposal by our Board of Directors to reclassify Facebook stock.
