In a 2005 presentation, Steve Jobs explains the then-emerging concept of podcasting to an audience.

Here's a summary of his key points:

• Gauging Familiarity: He begins by asking the audience a series of questions to see how many have heard of podcasting, how many know what it is, and how many have listened to or subscribed to one, revealing that while the term was known, deep familiarity was still low.
• Defining "Podcast": Jobs explains that the word is a combination of "iPod" and "broadcasting." He simplifies the concept as a "radio show" that anyone can create and put on the internet for anyone else to listen to.
• The Power of Subscription: He highlights the subscription model as a key feature. Users can subscribe to a show, and new episodes are automatically downloaded to their computer and then synced to their iPod.
• Early Growth and Statistics (as of 2005): He shares some "factoids" to show its rapid growth, mentioning there were over 8,000 podcasts and 6.2 million Google search results for the term.
• Key Advantages: He points out that because podcasts are distributed over the internet and don't use radio spectrum, they are free from FCC regulation and have a worldwide reach, allowing anyone in the world to listen.
