I&#x27;m a big fan of podcasting, and I totally rely on iTunes for podcast discovery, indexing, curation, and syndication. Many Apple critics don&#x27;t seem to appreciate this amazing service. Whatever Apple&#x27;s motive was at the beginning (probably to promote the sale of iPod and iPhone hardware), podcasting has taken on a life of its own.<p>Most of my favorite radio shows are now available as podcasts, including ESPN. These podcasts are generally available with 24 hours after the first radio broadcast. Broadcasters generally edit out the commercials that radio listeners hear. Some broadcasters also insert a few new ads, often at the beginning or end of a podcast.<p>Commercial radio broadcasters everywhere have enjoyed a long run of high profitability, but their business model is under threat now. The tradition of free podcasting doesn&#x27;t fly with them. Podcasting as we know it may be over soon unless we take steps to preserve it.
