Final answer:
In 2005, Steve Jobs likened podcasts to 'TiVo for radio' due to their on-demand nature. Podcasts have experienced significant growth, with listeners enjoying a variety of topics and celebrity-hosted shows. This shift reflects the continued evolution of radio into the digital realm.
Step-by-step explanation:
In 2005, Steve Jobs referred to podcasts as being like 'TiVo for radio.' Unlike traditional radio programming that requires one to tune in at a specific time to listen to a desired show, podcasts allow users to download audio shows and listen to them at their convenience. This ability to control when and where to listen is similar to how TiVo allowed users to record television shows for later viewing. Podcasting harnesses the power of the internet to offer a wide variety of topics and enables celebrity talent like Anna Faris and Ricky Gervais to reach audiences through this medium. The United States has seen significant growth in podcast listeners, with over 106.7 million people and 77.9 million listening at least once a week. The rise of podcasts demonstrates the evolution of radio and its adaptation to the digital age, leveraging technologies such as smart speakers to increase their accessibility.
