For Instagram, this is an obvious move to further monetize its popular photo and video-sharing platform. The way the company handles ads isn't as intrusive as something like YouTube -- as a user, you don't have to wait to scroll past and see what your followers have been posting -- but the nature of the feed means it's still hard to ignore them completely. That, combined with its 400 million users, makes Instagram an attractive place for companies to spend their ad dollars. For normals, however, it means the service might feel just a little more commercialized than before.
