You never know, maybe so or maybe not. Many in the younger end of the audience have grown up with the Internet, iPods, etc., and really pretty much just want radio to be a jukebox.(hence, the explosive success of Pandora, which was just this week named the most listened to "radio station", if u want to consider it that, in LA.) And these people are no longer just teens/20's. This applies to many in their 30s/40s. I know it really bothers many, and maybe it should, but I'm not sure the lower end of the 25-54 demo really cares about the "full service" elements of stations like WIVK any more. If they need weather warnings, live traffic conditions, breaking news, latest happenings in the area, or celebrity gossip; These are all available instantly on demand now from smartphones via apps & social media such as Facebook & Twitter, which most everyone uses now. Granted, the upper end of the demo are not as technologically savvy, or willing to be, but there is a big line around the 45 year old mark and under that indicates a real shift in the way that audience uses radio today.
As I say, I'm not saying this is a good thing, but I don't necessarily see WIVK's/Cumulus's move towards this trend as a death nail in WIVK and similar heritage stations. After all, they have to give the target demo what they demand. Otherwise, if they choose to age with their older audience out of the 25-54 demo, they become irrelevant to advertisers and lose profiteability.
