NAB has been pushing for the activation of FM chips, which can be found in most smartphone models, for years. Pilot has tracked activation rates since 2012. NAB also runs the website freeradioonmyphone.com, an advocacy group including NPR, APM (American Public Media), and NextRadio which gathers information and statistics about the push for making FM radio available on smartphones.
NextRadio is part of all this, of course, as its app provides an enhanced FM tuner for phones with activated FM chips.
