WhatsApp is a free application, but Facebook still wants to monetize it by implementing advertising.
What is known
Advertisements will appear in the “Status”, just asIt works in Instagram Stories. It will occupy the entire screen and display the name of the company. It is currently unclear whether Facebook is going to insert it somewhere else, but I would not want it to be too intrusive.
The company also wants to simplify in-app purchases. The product catalog can be viewed and sent to friends directly in WhatsApp, without going to the browser.
