Reverb is a podcasting application that exists to help users discover new content. I conducted an extensive literature review on podcasting, radio, and community oriented applications for iPhone. The research revealed two existing problems for podcasting applications: first, that a gap existed for an application which connected users through a social component. Second, finding new podcast stations to listen to was a difficulty for users. Reverb is a community-centered podcasting application that helps users discover new podcasts through a variety of interactive methods: collected data, their friends, or their preferences. Reverb then recommends new podcasts that can fit a tight schedule, a boring evening, or a rainy day with a cup of tea.
