The AskHistorians Podcast showcases the knowledge and enthusiasm of the AskHistorians community, a forum of nearly 1.4 million history academics, professionals, amateurs, and curious onlookers. The aim is to be a resource accessible to a wide range of listeners for historical topics which so often go overlooked. Together, we have a broad array of people capable of speaking in-depth on topics that get half a page on Wikipedia, a paragraph in a high-school textbook, and not even a minute on the History channel. The podcast aims to give a voice (literally!) to those areas of history, while not neglecting the more commonly covered topics. Part of the drive behind the podcast is to be a counterpoint to other forms of popular media on history which only seem to cover the same couple of topics in the same couple of ways over and over again.
