Soma Media and IDG World Expo today announced the release of MacworldEncore, the first suite of products enabling people to purchase Macworld Conference and Expo presentations online and on DVD-ROM.

The first MacworldEncore DVD-ROM set features more than 80 presentations from January’s Conference and Expo in San Francisco. Each presentation includes full-screen PowerPoint slides, live demos and synchronised audio, searchable speaker bios and abstracts, and iPod and iPod video compatibility.

The MacworldEncore Online product features the same content and functionality, but further enables people to download presentations individually and immediately from the web. The cost for individual presentations ranges between $5-$30, and the DVD-ROM set costs $299.

“We are excited to bring our innovative conference proceeding recording and delivery technology to the Macworld audience,” said Romy Randev, president of Soma Media. “Providing Macworld's content on DVD and online creates a comprehensive library of the Mac market's best technical presentations.”

Both the DVD-ROM and the web versions are now available for purchase. For a limited time, MacworldEncore is offering a $5 coupon that can be used to download presentations online. (Google Checkout coupon code: macworldencore$5off)
