Microsoft’s Copilot advertising has been criticized by an industry watchdog for its productivity claims and confusing use of Copilot branding. The BBB National Programs’ National Advertising Division (NAD) has reviewed Microsoft’s Copilot advertising, and recommended that the software giant discontinues or modifies productivity claims about Microsoft 365 Copilot and more clearly disclose the limitations of its Business Chat feature. Microsoft 365 Copilot Chat as it’s known now, started off as Bing Chat Enterprise before Microsoft then rebranded it, confusingly, to just Copilot. Somewhere in the middle of all this rebranding, Business Chat — which was originally a chatbot in Teams — is now Business Chat for Microsoft 365 Copilot. It’s all part of trying to make businesses use Copilot more, and then pay extra for the Microsoft 365 Copilot subscription.
