Some 60 years ago humans first began transmitting television signals powerful enough to reach beyond our earth's atmosphere. Since then the media has continued to broadcast messages from I Love Lucy to the five o'clock news into space, potentially reaching intelligent alien life forms beyond our solar system.
Which of course is pretty hip. I'm sure radio will drop packets though. You'd certainly need a liberal RSS parser on the other end.
But then again these are ALIENS so they probably have AWESOME parsers!
