An anonymous reader writes "During his company's quarterly earnings call, Facebook co-founder and CEO Mark Zuckerberg discussed how Instagram will be monetized. The answer isn't too surprising: there is a big expectation for the app to one day be profitable, and advertising will be the name of the game. 'Kevin [Systrom] has always been clear that we're building Instagram to be a business,' Zuckerberg said. 'We expect over time to generate a lot of profit from it. We think the right focus for now is to continue increasing the footprint of Instagram and, when the right time comes, we'll think about advertising.'"
