So anyway, what was this really "huge" channel shakeup? It seems like it was more of a bad thing than good. Just because people had to reprogram their presets, or was there something I don't know about?
Most have been small tweaks. The biggest I remember (aside from Nov 12th) was April of 2006. ClearChannel won the rights to put commercials on their channels so XM had to immediatly cloan 4 channels to keep the 69 commercial free channels moniker to match Sirius. They added Flight 26 to shadow The Mix, Hitlist to shadow Kiss, Eascape to shadow Sunny, and US Country to shadow Nashville. They dropped 4 channels as well. This happened about 2 months after they split Top Tracks into Top Tracks and Big Tracks.
