That's a country with a very high penetration of DAB+ radios. DAB+ is a
modulation scheme that combines several program streams -- up to 30, IIRC
-- onto one broadcast on a single RF channel. It's excellent for countries
that have national radio networks where one can feed multiple sites on the
same channel and have seamless coverage.
DAB+ wouldn't do as well in the United States, where national networks are
the exception rather than the rule, which is thousands of privately owned
local stations that compete one with another. The digital broadcast
standard here is "HD Radio", which has far lower penetration and isn't
popular with listeners. "HD Radio" also uses the same spectrum as AM and
FM, so there's no spectrum to be freed by shutting down the analog modes.
Listeners in this country aren't buying "HD Radio" receivers. Shutting
down AM and FM would leave the U.S. with no broadcast radio at all
(Internet streaming is not a workable substitute).
