So, I pulled this from search engine watch. Apparently Google is part of a coalition of companies petitioning the FCC for some of the airspace that will be vacated by broadcast television when the move to digital TV takes place in a couple of years.
Personally, I like this idea. I currently have one viable option for high-speed: cable through Comcast, and I'll just say that as an ISP they leave a whole lot to be desired. We generally have a couple of down times a month.
