In the high-flying world of HD video and new media, it is no surprise that the oldest form of communication still alive has moved to the stratosphere. Sirius XM satellite radio has revolutionized the medium, and led to numerous people making radio a part of their lives again. The early 1900s, when entire families would crowd around a box the size of a small refrigerator, are long gone, but thanks to satellites, radio is back in the greater public ear.

The idea began in the early 1990s, when Sirius and XM Satellite Radio's respective parent companies were founded. Over the years as technology evolved and the services grew more and more popular in the United States and elsewhere, Sirius and XM merged to form Sirius XM Radio in 2007. The merger proved controversial, as it made Sirius XM the sole provider in the US; however it has since been proven by the Department of Justice that the merger was not enacted to decrease competition.

Sirius XM Radio is only looking to expand its services for the future. With applications released for Apple's iPhone and iPod Touch, users will be able to listen to satellite radio as easily as they could place a call on their mobiles -- a natural progression in the technology.
