Final answer:
Companies producing CDs are affected by digital music, as streaming services and downloads become mainstream, similar to how prior music formats were superseded.
Step-by-step explanation:
CD production companies are currently being impacted by digital music the same way previous music formats were affected by technological advancements. With the rise of music streaming services and downloads, consumers are moving away from purchasing physical CDs. This shift mirrors the impact past innovations, like the iPod, had on devices such as the Sony Walkman. Digital music platforms offer vast libraries of music without the need for physical storage, making it a more convenient option for consumers.
