It was almost the entirety of AM radio for the past 40 years. Sports and this right-wing trash. On in the background at every work place, hardware store, and cafe until Muzac took over. Had that ranting asshole and his friends pumping into our ears wanting it or not. Many areas of the country had only that and Country Music for hours in any direction.
When I said "if you knew what you were doing" I meant you can build an AM receiver out of literal trash with a middle school understanding of electrics but no one bothered because you had one built in to every car, every tape player, boom box, alarm clock, and anything else with a speaker. You had a radio in every room of the house and 2 in the garage even if you never turned it on. There's no way to believe that phones have less cultural push than AM radio had pre-1990.
Sorry, didn't pay my Netflix cultural tax this year. Maybe I'll sail the sees for it.
