Why?
Because of digital streaming Interent music and because of Sirius and XM radio through satellite.
I have an old, old Fisher Studio Standard AM/FM tuner that still provides outstanding AM/FM and it is over 35 years old. I bought it because it was one of the first digital tuners. At the time, AM/FM were big, no CDs, no video switching VHS, Betamax or blu Ray DVDs. You either listened to 78 or 45 RPM records or reel-to-rell tape. Therefore tuner specs were critical and competiton produced some great AM/FM receivers and tuners. Yes, today, AM/FM is mostly an after thought!
