Final answer:
Rogers Wireless offering deals on larger data plans is an example of market segmentation, which is about targeting specific customer groups with shared characteristics. Bundling and product differentiation are related concepts but not the focus of the question.
Step-by-step explanation:
When Rogers Wireless offers a deal on bigger data plans for its wireless customers, this is an example of market segmentation. Market segmentation involves dividing a broad consumer or business market into sub-groups of consumers based on some type of shared characteristics. In this case, Rogers Wireless is targeting a segment of customers who are interested in larger data plans and may require different usage levels compared to other customers.
The concept you've mentioned about bundling, where firms sell multiple products or services together at a special price, is related but not identical to market segmentation. Bundling is often used to offer savings to consumers and can be part of a company’s strategy for product differentiation, which is any action that firms take to make consumers think their products are different from their competitors'. However, the question at hand more accurately relates to market segmentation, since Rogers Wireless is catering to a specific customer need with its data plan offer.
