These problems were\nreduced to some extent with the introduction of frequency modulation (FM),\nwhich could also provide stereo transmission and CD-quality audio, but analog\nradio was still not devoid of channel imperfection effects and limited coverage\narea. During 2003, two commercial start-ups, XM and Sirius (these merged and\nbecame SiriusXM<sup>\u2122<\/sup>), introduced the huge footprint of\nsubscription-based digital satellite radio in the United States, with a revenue\nmodel similar to that of Pay-TV channels. Around the same time, WorldSpace\nRadio started satellite broadcasts for Asia and Africa.<o:p><\/o:p><\/p><p>The Satellite Digital Audio Radio Services (SDARS) enabled\nmobile car audio listeners to tune into the same radio station anywhere within\nthe satellite\u2019s coverage map, limited only by intermittent blockage of\nsatellite signal due to buildings, foliage, and tunnels. XM satellite radio\ntook the lead in circumventing the blockage problem by installing terrestrial\nrepeaters, which transmit the same satellite audio in dense urban areas and\ncreate a hybrid architecture of satellite and terrestrial broadcasts.<o:p><\/o:p><\/p><p>Around the same time the&nbsp;<i>traditional<\/i>&nbsp;terrestrial\nbroadcasters also charted a digital course\u2014for two reasons. First, they\nperceived that their life span on the&nbsp;<i>analog<\/i>&nbsp;concourse had to\nbe quite short, as the world migrates to the higher quality&nbsp;<i>digital<\/i>&nbsp;runway.\nSecond, the frequency spectrum is getting scarce, so additional content within\nthe same bandwidth could be delivered only by digitizing and compressing the\nold and new content, packaging it, and then broadcasting it. Thus, the world\nstarted migrating from analog to digital radio. These techniques for radio\nbroadcast had the advantages of clearer reception, larger coverage area, and\nability to pack more content and information within the existing bandwidth of\nan available analog radio channel\u2014as well as offering users increased control\nflexibility in accessing and listening to program material.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Amplitude modulation (AM) was the dominant form of radio broadcasting during the first 80 years of the 20th century, but channel fading, distortion, and noise led to poor reception quality.
