wat does brand extension mean? cud u give me an example?

Brand extension or brand stretching is a marketing strategy in which a firm marketing a product with a well-developed image uses the same brand name in a different product category. The new product is called a spin-off. Organizations use this strategy to increase and leverage brand equity (definition: the net worth and long-term sustainability just from the renowned name). An example of a brand extension is Jello-gelatin creating Jello pudding pops. It increases awareness of the brand name and increases profitability from offerings in more than one product category.

Wat is this saying? Like Secret be an example?

I don't know how to simplify the above passage from Wikipedia.

Secret seems to make only deodorant products, where Jello extended it's original gelatin to pudding pops.

This means that brand extension refers to when a company uses the same brand name for a new product in a different category. It is a marketing strategy used to capitalize on the existing reputation and awareness of a brand and extend it to new products. For example, Secret, a well-known brand of antiperspirant and deodorant, introduced Secret Body Cleansing Wipes, extending their product line to include personal hygiene products beyond just antiperspirants. This helps Secret leverage its established brand equity and potentially increase profitability by expanding into new market segments.
