This paper looks back at the last 10 years of the use of podcasting as a language teaching and learning tool. It considers the potential that was identified at the early stages, to the work that has been carried out to evaluate whether this potential has actually been realised. It presents a taxonomy of podcasts that can be used for language learning and suggestions regarding the format of podcasts. It also reports on how users utilise podcasts and on how different audiences have markedly different practices. It concludes that podcasting allows learners flexibility and personalised learning.
