Facebook celebrated an incredible milestone today with the announcement that it had reached 1 billion monthly active users, and it appears they did it ahead of schedule after claiming 955 million monthly active users in July. As a celebration of sorts, the social giant has released its first ever ad campaign, created by Wieden + Kennedy who you may recognize as the creative genius behind Nike’s powerful commercials. The ad campaign will roll out in 13 countries, including the U.S., Brazil, Mexico, Russia and Spain. Check it out below and let us know what you think!
