Why a product like radio declined and now once again emerging as an entertainment medium?

Radio's decline was primarily due to the rise of television and digital streaming platforms, which offered more visual and on-demand content. However, it is experiencing a resurgence as podcasts and internet radio have gained popularity, providing accessible and diverse audio content. Additionally, the growth of smart speakers and mobile apps has made it easier for users to listen to radio content anytime, anywhere, revitalizing interest in this medium.
