Podcasting was born out of some work I did on the RSS format to allow it to carry enclosed files, along with former MTV veejay and radio host Adam Curry's desire to disseminate audio shows in an easy way. He built the first version of iPodder in Applescript and released the code less than six months ago. The technology has caught on quickly. Already, hundreds of podcasts are available, including content from National Public Radio and progressive talk station Air America, as well as homemade shows on technology, music, cooking and pretty much anything else someone feels like talking about.
