Back in the day, cars had an AM radio. Then FM was added along with an 8-track player. In the 70s, the 8-track disappeared and was replaced by the cassette. In 1984, the first in-dash CD players started showing up and for a while, AM/FM/Cassette/CD players co-existed.
Around the turn of the millennium, satellite radio options were available, so we had AM/FM/Cassette/CD (and sometimes 6-pack changers)/satellite. And let’s not forget the cars that came with AUX inputs for things like iPods and smartphones and USB jacks for thumb drives. That’s a lot of options for sound.
But in 2009, the last factory-installed cassette player was shipped. And in 2013, GM announced two vehicles that would no longer come with CD players because the intended buyers had no interest in them. This year, Hyundai said that all of its 2016 models wouldn’t bother including a CD player for the same reason. How much longer before other manufacturers do the same thing?
