Will New Radio Technology Anialate FM Radio?

According to CNN.com, "a growing number" of Americans are ducking from the long commercial breaks of FM radio and investing in satellite radios. With these radios from XM and Sirius, listeners can tune into over 120 channels with no commercials at all. According to CNN, 30% of airtime on U.S. radio is taken up by commercials. In order to obtain this service, a $13 a month charge is issued. Both Sirius and XM have signed major deals with automakers which have made their radios standard features in cars. Is this a good thing to invest in? What will become of FM and AM radio? Local radio shows?
