McDonald’s is testing advertisements from other brands on digital drive-thru menu boards at a limited number of company-owned restaurants. The adverts will appear after customers place their orders, while they wait for their food, as the company explores ways to provide post-purchase content and potentially create a new revenue stream.

The trial comes as McDonald’s faces falling US sales. The company has also announced plans to develop ArchIQ, an AI assistant demonstrated identifying repeat customers and remembering their usual orders, although McDonald’s did not immediately comment directly to The Verge.
