In 2016 Sirius discontinued broadcasting from tundra orbits. Their newest FM-5 uses geostationary. [1]
Satellite radio was tried a few times in other geographies, but only in North America did it succeed. [2] In 1999 Worldspace launched for EMEAI, and looks like it collapsed in 2008. MobaHo! was a mobile satellite digital audio/video broadcasting service in Japan whose services began on October 20, 2004, and ended on March 31, 2009.

- m4rtink 7y agoInteresting, I totally missed that they use GEO now! Still pretty cool that one can receive digital radio without a directional antena from a satellite all the way up 36000 km in GEO. Though looking at the article about Tundra Orbit you have linked it was 25000 x 39000 km already, so not that much of a difference.
