If the term GridNetworks seems vaguely familiar, it's because it is. After being invested in by Cisco back in March, the outfit is finally pushing out a quasi-tangible product in the form of GridCast TV. You see, the service actually relies on other boxes to handle the dirty work, meaning that content owners have complete control over how their material is distributed and via what channels. By leveraging UPnP technology, content owners can beam out programming to anyone with an internet-connected PC, Xbox 360, PlayStation 3 and HDTV (for example), and we're told that online video mainstays Revision3, IndieFlix and havocTV have already begun using it. Good luck out there -- with a space this crowded, you're bound to need it.
