What does a single rating point represent in television viewership?

A single rating point in television viewership represents one percent of the total potential television audience. This metric is essential because it provides advertisers and networks with key insights into how many viewers are engaging with a program relative to the entire population of potential viewers. For example, if a show's rating is 10, it indicates that 10% of the total target audience is watching that show, making it a crucial tool for measuring and comparing the popularity and reach of different television programs.

Understanding this concept allows networks to make informed decisions about programming and promotions, while advertisers can gauge where to allocate their budgets effectively. Other options do not correctly convey the meaning of a rating point, focusing instead on specific time periods, individual audience figures, or channel-specific data.
