Ajit Pai, the new chairman of the FCC, last week issued a call for activation of the FM chips in smartphones. The vast majority of smartphones sold in the U.S. have FM chips, but they're activated in only about 44 percent of the top brands, Pai told attendees at the North American Broadcasters Association symposium on the future of radio and audio. Although that's nearly twice the 25 percent figure of two years ago, it's not good enough, Pai suggested, noting that 80 percent of smartphones sold in Mexico have their FM chips activated.
