From several sources in the last week:
"Google announced a partnership with satellite radio firm XM that will allow advertisers to use Google's technology to buy commercial time on XM stations."
Here's why I'm filing this under "Impractical": Why should I pay to listen to satellite radio and have to listen to ads? Besides, I actually like hearing static on radio: it reminds me that, despite its attempts to usher in the Age of Perfection, technology isn't. Nor can it make people perfect.
That's why I don't have cable tv: I can't see paying $300 or $600 a year to watch advertising. In any case, the $100 Radio Shack rotating antenna above my house picks up about a dozen tv stations out where I live, about 50 miles from the nearest really big city.
Plus, I get a bonus from the pod-shaped device situated on my roof: makes my neighbors nervously ask what it is.
