Final answer:
Rating systems like Nielsen Audio and Arbitron are used to measure radio listenership, which guides radio programming and advertising.
Step-by-step explanation:
Yes, there are rating systems in place for other forms of media such as radio. Specifically, Nielsen Audio provides ratings for radio listenership by collecting data to determine the size and composition of radio audiences. Another example is the Arbitron ratings system, which was historically used for radio audience measurement before being acquired by Nielsen. These systems enable advertisers and radio stations to understand listener demographics and preferences, shaping the programming and advertising strategies accordingly.
