IDG, the company behind Macworld and more than 300 other publications, will soon launch iPodworld — a magazine dedicated to Apple’s iPod, iTunes and iTunes Music Store. iPodworld will feature iPod and music news, previews of upcoming products, software and hardware reviews, digital lifestyle how-to articles, and reviews of music available from the iTunes Music Store. It is not yet clear whether the magazine, which will be available on newsstands in August, will be a single issue, quarterly or monthly. Update: Macworld informed us that the magazine will be a special, newsstand-only supplement — not a new monthly publication.
