“Instagram as a Growing Business” Is an Odd Euphemism for Adding Ads blog.instagram.com

Instagram:

We have big ideas for the future, and part of making them happen is building Instagram into a sustainable business. In the next couple months, you may begin seeing an occasional ad in your Instagram feed if you’re in the United States. Seeing photos and videos from brands you don’t follow will be new, so we’ll start slow. We’ll focus on delivering a small number of beautiful, high-quality photos and videos from a handful of brands that are already great members of the Instagram community. 

You knew this was coming sooner or later.
