Debranding
Debranding has two definitions, both aligning with market base strategies, but having two separate meanings
Debranding (de-corporatizing) occurs when a company removes its name from its logo for a marketing campaign, this is usually in an attempt to make themselves appear less corporate and more personal.
Debranding (transitioning into "generic") occurs when a company with a well-known brand opts to appear more generic. This means the company will eliminate advertising and reduce prices and debranding in this sense can increase profit margins.
