This is more about the digital dashboard than anything else. lots of stations have their own apps and there is a strategy behind that, but radio stations also want to be part of the apps that are being pre-programmed into the new digital dashboards in cars (Like Toyota Entune, Ford Sync, Hyndai Blue Link & Cadillac Cue.) Google them and you will see that many of the new car in-dash systems don't actually have a hard wired radio. It's more like an ipad screen that comes loaded with a digital radio, GPS, phone connect, internet browser & pre-programmed apps like I Heart Radio, Pandora & Tune In Radio. Getting individual radio apps pre-programmed in the car will need a huge amount of nationwide buzz or a huge amount of money for the car makers. (maybe both!)
