Commercial broadcast radio is, in olde-worlde communications parlance, *narrowband* modulation of a carrier. Wideband - *not* broadband - modulation refers to signals with transmitted bandwidth that is a significant fraction of the carrier frequency. The baseband signal is essentially the information-bearing signal, sans any modulation of a carrier.

Broadband isn't a speed, it's a signaling architecture. The alternative is baseband. Ethernet is baseband. Broadcast radio is broadband.
