Laurie Sullivan writes in an article in Information Week, "Finding Profits In Podcasting":

Oracle is among the latest companies to embrace podcasting, which is the act of publishing digital-audio broadcasts to MP3 players such as Apple Computer’s iPod and the Dell Jukebox via the Internet.

Oracle, which began offering podcasts from its Web site in May, now envisions technologists donning earphones as they traverse its Oracle OpenWorld conference next month. Oracle will publish two 10- to 20-minute podcasts daily during its user conference on subjects such as middleware, applications, databases, and grid technologies, designed for the ears of the software developers and database administrators who buy its products.

What a great idea for your next tradeshow. Why not offer a podcast on your blogsite to prime your prospects? Your prospects won’t wade through a white paper until they’re ready to buy, but a podcast gets them ready to hear your message.
