It's been a long, long time coming but the once separate XM and Sirius universes are now finally, officially intermingling, resulting in some new channels, some renamed channels, some moved channels, and no doubt quite a bit of confusion for satellite radio listeners. The short of it is that XM users can expect to find 22 new channels, while Sirius listeners get 11 (mostly music channels), with a whole slew of other channels either moved, renamed, or both. Dig into the links below for the complete details, and expect to wait two to five minutes to receive the update if you haven't already turned on your radio today.
