|Starting in January, Instagram users might be surprised to find their photos or faces starring in advertisements when they log onto the photo-sharing service or are browsing Facebook.
The new terms bring Instagram's terms of service in line with parent company Facebook and are part of a wider push to scale revenue, especially on mobile devices where Instagram is popular. Converting user content created when a post is "liked" by a user and turning that into an ad is a core part of Facebook's ad model.
In a post on the company blog, Instagram said the changes were made to prevent spam and to more closely integrate its service with Facebook.
"Nothing has changed about your photos' ownership or who can see them," the blog post says.
Minors are included in this scheme as well. If a user is younger than 18 years old, he or she acknowledges that a parent has agreed to letting Instagram use his or her content for advertising purposes.
"I don't think people should freak out," Mr. Schafer said. "The Internet freaks out real easily. This is what happens every time."
"They have no interest in re-selling individual photos. I don't think that's the intention here," he said.
