A podcaster is someone who creates and hosts a podcast, which is an audio show people can download or stream on their phones, computers, or tablets. Think of it like a radio show, except you can listen whenever you want, and there are podcasts about almost any topic imaginable: science, history, comedy, sports, true crime, storytelling, and even video game walkthroughs.

Some podcasters work alone, recording themselves talking into a microphone in their bedroom or home office. Others work with co-hosts or interview guests, like the way talk show hosts interview celebrities on TV. A science podcaster might explain how rockets work or why the sky is blue. A history podcaster might tell stories about ancient Rome or the American Revolution. Some podcasters make silly comedy shows, while others have serious conversations about current events.

Unlike traditional radio hosts who broadcast at specific times, podcasters create episodes that listeners can enjoy anytime. Some podcasters have millions of listeners and earn money through advertising or subscriptions, while others create podcasts purely as a hobby, sharing their interests and knowledge with anyone who’s curious enough to listen.
