Akimbo Systems is getting set to launch their television-via-internet service. They're working with a smattering of sites that provide video (including, of course, a porn site or two) that are instantly accessible via your television, thanks to a big silver box.
It's an interesting attempt to circumvent the cable/satellite/over-air broadcast model entirely by using the internet in a new way, and it's great to see a new company innovating in the space. However, unless they sign on some pretty significant heavyweight content providers, they'll have a tough time luring customers with their current offerings (which seem too niche and not that extensive). They're also limited to DRM-laden Windows Media 9 video, so don't expect to be playing your own DVD backups captured as MPEGs anytime soon.
