While I would have problems handing a four-year old an iPod long enough to actually watch something, I'm surprised it took someone this long to start offering video podcasts for toddlers and preschoolers. You can watch the files on an iPod or your PSP, if you're brave enough to give the kid control of your portable electronics. I also know firsthand how quickly children of that age group get into playing games with the characters they see on television and read about in books. The next step is here: tailoring on-demand content to even very small children. Between these podcasts and web destinations built for children to be able to use and navigate, this is a market everyone wants to be a part of. It's not so much that this content is being directed to children, it's that the content providers want the children to have control over it.
Here the kids watch things on DVD and videos saved onto the computer. It's not that we're against television as such, all things in moderation, it's the ceaseless advertising for snacks and toys that we try to limit their exposure to. We've also found that the few times we've watched something on network television it was a nightmare. Why? Without it being on a Tivo or on DVD if Luke or Ivy want to use the bathroom or grab a snack they get incredibly upset when we can't pause the show or rewind to show them what they've missed. Unlike most of us, many kids will grow up only with content on-demand in their homes, so the concept of changing your schedule to watch a show will most likely be completely foreign to them by the time they have grown up.
It's crazy the things that are already anachronisms. I used to invite people over to my house on Fridays to watch the X-files, if you didn't tape it or catch it that night you were sunk. Can you imagine telling your kids you had to look up library books on little slips of paper in a big wooden file?
