Most of the known AM figures claim they produce a program, three hours daily. Check the ads: seven minutes before the hour, seven minutes, after, two to three minutes on the quarter hour and five minutes on the half hour, and the bloviators produce about two hours out of three.
Yeah, same for TV, 20 min of program, 10 min commercials. Too bad we can’t install commercial-killer programs on TV’s like we can on our computers...
