The history of portable satellite radio is short compared to traditional terrestrial radio, but it has rapidly changed the face of radio listening like no other technology in recent memory. The two major satellite radio services, XM Satellite Radio and SIRIUS Satellite Radio, offer a stunning array of programming.
Their popularity has stunned many in the radio industry and some industry veterans worry about the future viability of traditional broadcast radio.
Digital Audio Radio Service (DARS) was established by the Federal Communications Commission (FCC) USA, in 1992 by establishing certain segments of radio frequency for satellite broadcast on radio.
WorldSpace broadcasts satellite audio and multimedia content to Africa, Asia, the Middle East and Europe. Founded in 1990, WorldSpace conceived of and built the first ever satellite radio infrastructure in the world. Today, the WorldSpace satellite network consists of two geostationary satellites: AfriStar™ and AsiaStar™. Each satellite broadcasts three beams capable of delivering more than 80 crystal clear audio and multimedia channels directly to portable receivers and personal computer adapters.
