The National Association of Broadcasters has been asking mobile makers to change this. But the mobile industry, which profits from selling data to smartphone users, says that with the consumer's move toward mobile streaming apps, the demand for radio simply isn't there.
In the words of NPR's Robert Siegel
Samsung, Apple and LG are among those who have not switched on the chip, but HTC and Motorola chips haven't been blocked, Sprint has turned on the FM chip for phones on its network.
The smartphone has fueled a change in media consumption habits and it's a growing challenge to radio as the go-to audio source for news. To get local broadcasts, Users increasingly download podcasts or stream from news apps where they can skip or pause segments. As popular as this form of consumption is, these apps all suck up costly data.
Aside from the huge benefit he sees for the radio industry, Smulyan says users could avoid expensive data charges and save battery life if they listen to the FM chip for free.
