Final answer:
The term for brands owned by the retailer is 'Private label brand.' These brands are exclusive to the retailer and can help differentiate from competitors.
Step-by-step explanation:
The term used to refer to brands that are owned by the retailer is Private label brand. These are products that are manufactured by one company but are sold under the retailer's brand name.
Retailers might choose to sell private label brands to differentiate themselves from competitors and to offer exclusive products to their customers. For example, a grocery store might sell its own house brand of cereal alongside national brand names. This strategy allows retailers to control product manufacturing, pricing, and branding.
