XM Satellite Radio Surpasses 5 Million Subscribers

XM Satellite Radio on September 27th surpassed 5 million subscibers . They even expect another million by the end of this year. This industry is growing so quickly. There are only a few companies out there right now who offer satellite radio but its booming either way. XM being the leading company is offering more and more new channels every year to accommodate all listeners. Sirius Satellite Radio, the next largest company is offering a Howard Stern channel this fall. Both companies offer tons of sport choices and Sirius even has every pro football game on a channel. There are even over 100 channels of commercial music to choose from. Both companies also offer channels for women, comedy channels, cooking channels, car channels, and the list goes on and on. My question is; what's going to happen to good old fashion radio. If this industry continues to boom like it is now will we even listen to regular radio. There is talk about major automobile companies making deals with these companies so cars come with XM already built into the car. Why would you even listen to the radio when you have satellite? How much is this going to hurt our FM or AM radio stations.
