The early 2000s era Nokia feature phones that were extremely popular in India had an FM tuner. It was a killer feature and I have seen people young and old playing the radio on their phone with the speakerphone turned on. Others might have their earphones plugged in. It kinda captures the zeitgiest of the time just as boombox toting youth in the 80s or early 90s or the Sony Walkman generation would do for the earlier periods.
It is a shame that the arrival of smartphones made that feature disappear from mobile devices.
