Final answer:
A yoga business channel focusing on classes for specific groups uses narrowcasting to provide specialized content tailored to the needs and preferences of the targeted audience.
Step-by-step explanation:
The type of yoga business channel that focuses on a series of classes tailored to a specific group of people is best described by narrowcasting. This approach involves the creation of specialized content for a targeted audience, much like major networks segment their programming to cater to distinct preferences such as reality TV or sports. For instance, a yoga studio may offer classes specifically designed for athletes, expecting mothers, seniors, or individuals dealing with stress, thus ensuring the content is relevant and beneficial to the participants' unique requirements. Even though the westernization of yoga has shifted its focus, instructors may still occasionally use Sanskrit in their teachings to maintain a connection to the practice's origins.
