Instagram, the photo and video-sharing app owned by Facebook, is the fastest growing social network with 35 million monthly smartphone users spending 257 minutes per month. Forty percent of their traffic is in the United States where 58 percent use the app every day. Seven in ten are women (18-44) with household incomes of $75,000 or more who are actively looking to be surprised, diverted and delighted. Instagram, according to research by L2 Think Tank, registers 15 times the engagement and double the engaged user base of its parent, Facebook.
