Facebook (FB) - Get Report is planning to signal its control of Instagram and WhatsApp by adding its name to both apps, the Information reported, and both apps will become "Instagram from Facebook" and "WhatsApp from Facebook."

The change won't affect any of the apps' functions.

The "from Facebook" branding will be visible inside the apps - users will see it when they log on, for instance - and elsewhere, such as in app stores. A Facebook spokesperson told the Information that it wants "to be clearer about the products and services that are part of Facebook." Up until recently, Facebook had allowed the apps to operate and be branded independently.

Facebook's acquisitions are a central focus of a federal antitrust probe targeting the social media giant. The Federal Trade Commission is looking into whether Facebook acquired smaller technology firms with the intent of stamping out competition.

Shares of Facebook were down 1.9% to $185.30.
