Answer:
brand extension
Explanation:
Whizzle Corp. first introduced a line of toothpastes under the Whizzle brand name. A few years later, it introduced two different products, a mouthwash and a chewing gum, using the same brand name. Whizzle is using a brand extension strategy to market its products. Brand extension or brand stretching is the act of using an established brand name on new products in a bid to get fast visibility and patronage.
