Zuckerberg said "the camera is the composer" during an all-hands meeting with Facebook employees over the summer, according to someone familiar with the meeting.
The statement was an obvious nod to Snapchat, which recently rebranded itself as "Snap Inc., a camera company," but since day one has prioritized photo and video messages in its app.
During Facebook's quarterly earnings call in October, Zuckerberg explained that Facebook now sees the camera as the future of how people share and communicate.
"In most social apps today, a text box is still the default way we share," he said. "Soon, we believe a camera will be the main way that we share."
