Instagram Will Be a $10 Billion Business by 2019

Instagram is growing its user base rapidly and its advertiser base even faster. In September, Instagram announced it surpassed 800 million monthly active users, but the fact that it surpassed 2 million active advertisers was, perhaps, more interesting.

Instagram is well ahead of the curve its parent company Facebook (NASDAQ: FB) set, and that's an impressive feat. In a previous article, I wrote, "[Instagram] should be able to produce more than the $3.7 billion Facebook made when it reached the same level of users back in 2011." Indeed, Instagram will generate $4.1 billion this year, according to an estimate from eMarketer. The research group expects that number to balloon to $10.9 billion by 2019.

Let's take a look at what's fueling growth at Instagram, and the importance of that growth for Facebook investors.
