Satellite Radio

From OAPedia.com

Satellite Radio is a medium of radio that is broadcast across the United States, Canada, Asia, Europe, and Africa through satellites in space. XM and Sirius are the only satellite radio companies currently broadcasting in North America, with plans to possibly merge into a single company. Worldspace Satellite Radio broadcasts to the eastern hemisphere on multiple continents. XM and SIRIUS satellite radio are now available in Canada.

Opie and Anthony did ads for satellite radio during their time on WNEW. They saw the future of this new medium then, and thought it was stupid for their bosses to take money for ads for what was essentially competition. Eventually, terrestrial radio stations started doing anti-satellite radio ads. O&A soon became the first radio show to simulcast their satellite show on terrestrial radio (up until that time, terrestrial radio shows typically had their shows aired on satellite, but not vice versa).
