Microsoft's Copilot advertising claims have been challenged by the Better Business Bureau's National Advertising Division (NAD). NAD found Microsoft's productivity claims lacked sufficient evidence and recommended modifications. Additionally, NAD criticized the confusing Copilot branding across various products, particularly Business Chat. Microsoft, while disagreeing with NAD's conclusions, will adjust its advertising to clarify claims and address branding concerns.
