I am not in the radio business but I know some people who are.
They’ve been telling me for the past few years listenership is way down , and as a result, advertising income is way down as well.
One reason many AM stations have infomercials on the weekends , is because they’re selling airtime for those program length infomercials. It is an additional source of income.
I’ve noticed the infomercials. Maybe I’m dating myself as an old Rush listener.
