The messaging service WhatsApp on Monday will begin to display ads for the first time as parent company Meta seeks to make business changes to the encrypted global platform.

WhatsApp says that users will start seeing ads in some parts of the app, as owner Meta Platforms moves to a cultivate a new revenue stream by tapping the billions of people that use the messaging service.

Unlike other Meta apps, the company has traditionally kept WhatsApp ad-free. That’s set to change, though ads will be limited to specific areas of the app, away from your messages. Meta will soon include ads within the Status feature.
