When Sprint added some popular Sirius satellite radio channels to its streaming data customer packages years ago, it seemed like a great solution for those that like low-fidelity satellite radio through those (at the time) 1xRTT handsets. When Sprint's EV-DO handsets started shipping, Sirius was right there as usual but sounded the same (read: not that good). Those music channels did suffice in a pinch, but the value was just not there. Well, Sprint must have finally realized this, as a recent billing insert to customers states that Sirius streams will be going away in favor of 10 new genre-themes music channels, though no date was given on when the change / transition will take place. Could those eye-squinting Sprint Movies be on the chopping block next?
