AM Radio. Some will say that AM Radio has the largest audience of any media platform. Some are asking if it will survive in the future. There have been some headlines that a few car companies will no longer offer it. Tesla says the AM frequency interferes with the battery operations so Tesla's do not have AM Radio.  If you listen to AM Radio does that mean you are old? I listen to it a lot, mostly 770 AM. My kids will always insist on changing it when they are in the car. I guess that means I am old.
