Bedtime stories now available on children's iPods

Don Katz has a vision for the kids of America: He wants to take the technology that brings the Jonas Brothers to their ears and use it to deliver the Brothers Grimm. Nearly a third of children ages 6 to 10 are regular users of digital audio players, according to market research firm the NPD Group. And thanks to entrepreneurs like Katz, they can now use them to listen to bedtime stories.

In March, the Audible.com founder launched AudibleKids.com, where children can download books directly onto their digital audio players.

"I hear lots of people talking, saying that when they put their kids to bed, they put them down with an audiobook," says Audio Publishers Association president Michele Cobb.
