나카모리 아키나
The influence idols had on television led the 1980s to be known as the "Golden Age of Idols", in part due to Japan's economic bubble and growing commercial interest in them. Several figures who defined the Golden Age of Idols are Seiko Matsuda, Akina Nakamori, Kyōko Koizumi, and Onyanko Club. Television programs in which idols appeared often enjoyed high viewer ratings. Dentsu also created the "CM idol" business model, where idols were able to gain fame by singing and appearing in commercials.
