Instagram on Thursday revealed how ads will look like on the social network when they finally come to the photo-sharing app. The Facebook-owned company is treading carefully and says it will gently introduce users to the concept by posting a one-time sample ad for its US-based users “within the coming week.” Earlier this month, Instagram confirmed ‘occasional’ in-feed image and video ads were coming to the US. The company wouldn’t give timing details beyond “in the next couple of months.” Today, the company still won’t give a specific date, or even a month, but it is starting to show off its design for the ads. Instagram once again reiterated the need for ads on its service: “Our focus with every product we build is to make Instagram a place where people come to connect and be inspired. Building Instagram as a business will help us better serve the global—and ever growing—Instagram community.”
