Commissaries often carry other, bargain-brand radios, but according to former inmates and employees of the Bureau of Prisons and the Keefe Group, who spoke on the condition of anonymity, America’s federal prisoners are most likely to own a Sony. Melissa Dolan, a Sony spokesperson, confirmed in an e-mail that selling portable radios in American prisons has long been a “stable business” that represents “sizable” sales for the company. Of the models available, the SRF-39FP remains an undisputed classic, still found on commissary lists an impressive fifteen years after its initial release, making it nearly as common behind prison walls as Apple’s iPod once was outside of them, despite competition from newer devices like digital radios and MP3 players.
Fascinating. Though I’m not sure this is a metric Sony would ever want to tout.
