On Tuesday, Instagram announced that users can now browse photo feeds on the web -- something users have only been able to do on their mobile devices for the past two-odd years. The feed is, essentially, just a blown-up version of the one that exists on mobile, with one big difference: There's plenty of room in the margins for ads.
Our senior tech analyst, Christina Warren, created a mockup of what Instagram.com could look like if it began displaying ads in the style of its parent company, Facebook. A column of ads could sit just to the right of Instagram's photo feed, seamlessly mimicking the format of Facebook's News Feed pages. Navigation that links Instagram to Facebook could easily be integrated in the left rail, for that matter.
This is, of course, purely speculation. Neither Facebook nor Instagram have announced plans to incorporate advertising into Instagram's apps.
