Podcasting -- a system that delivers audio content from the Internet to a digital music player -- has been available for barely a year. But automakers are quickly embracing the medium's marketing and advertising possibilities.
General Motors, the Chrysler group, Lexus, Volvo and Acura are among the auto companies and brands that sponsor or have developed podcasts. The technology takes its name from Apple Computer's iPod, the most popular digital music player.
Automakers are experimenting with podcasting formats that range from 15-second commercials to 20-minute broadcast interviews.
