Two weeks ago, we featured free classes available online for prospective and newly-admitted b-school students. Today, we’re featuring podcasts. Almost all universities have podcasts these days, and if you’re interested in a school, it’s worth poking around the website for lectures or interviews. But here are the top five that stand out:

1. Knowledge at Wharton: Wharton’s podcast follows a traditional radio-interview format. A host sits down with an interesting guest to discuss a meaty topic, like the next generation of Internet search or the future of the book business. Podcasts regularly feature Wharton professors speaking about their own research, as well as CEOs, government officials, venture capitalists, and others. And you don’t actually have to download the files”you can just stream the interviews from the website.
2. Darden School of Business, Speaker Series: UVA’s Darden School of Business uploads recordings of anyone who visits campus as part of the Darden Distinguished Speaker Series, the Darden Leadership Forum, or the 50th Anniversary Speaker Series. That makes for a lot of podcasts featuring a wide variety of leaders, from former Mexican president Vicente Fox to Under Armour founder Kevin Plank.
3. The London School of Economics, Public Lectures and Events: The LSE seems to host speakers constantly, and it’s no surprise the school draws some big names. Besides professors, the roster includes a number of presidents, plus social media guru Clay Shirky and Nobel laureate Muhammad Yunus. This series is especially great if you’re interested in emerging markets or global business. But their offerings vary widely, and they aren’t necessarily what you’d expect. The archive includes lectures on contemporary art, climate change, and even Slavoj Žižek on the end of capitalism.
4. Insead, Leadercast: Also good to check out if you’re globally inclined is Insead’s Leadercast series. Professors sit down with European leaders like Thomas Rabe, CEO of German media conglomerate Bertelsmann, and Todd Stitzer, CEO of British confectionary company Cadbury. You can either watch them as embedded videos or download the audio as mp3s, and next to each video is an overview of the company discussed, for further reading.
5. Harvard Business School, Working Knowledge: It isn’t updated regularly, but HBS has an archive of their Working Knowledge podcast, which features faculty members discussing their research, current events, and the like. It’s not extensive, but the available content is worth a look.
