Remember when 14 minutes of commercials per hour seemed like a lot of clutter? We noted that Chicago’s Nine-FM plans to run only 9 minutes per hour when their 9,999 song marathon concludes. That’s a rarity. Today almost 1/3 of every broadcast hour is advertising. And now there’s a new term that media analysts are using to describe the problem: ad inundation. According to Variety, the commercial glut is eroding spot value, especially since most consumers know when the long commercial breaks occur and tune out. Add the commercial free satellite radio alternative, and it’s not surprising that five major banks have lowered their investment recommendations on the radio sector. If you ran a radio station, how would you deal with the issue? Give us your opinion on the Keener Bulletin Board.
