WGMD found its niche and is doing well. Thankfully for WGMD, its owner is happy with the profits he/she is making doing a live and local format in Lower Delaware. Delmarva (WDEL's owners) also seem to be doing quite well with their live and local format in the Wilmington Metro Market, so it can work in both small and medium sized markets.
Unfortunately, CC makes its money by selling national spots on their Premiere Radio Network shows (Rush, Hannity, Jim Rome, for a while longer Dr. Laura, Big D and Bubba, etc, etc). Of course the more markets those programs clear, means the more CC (Premiere) can charge to air those national spots. This is a different type of marketing strategy that makes the corporate offices money, but doesn't do much for the local radio business as witnessed by WILM's lack of local spots and the continuing shrinking of their local employee base.
Radio, as with all other parts of industry have the mind set to make the most possible money, even if it means having less employees (employees are a companies largest expense). The Radio business: goes automated computer, satellite syndicated programming, minimum to no local content, voice tracking, etc. Industry: closes American plants, moves those jobs to Mexico, Vietnam, China, India, etc, where they can get away with paying a Chinese worker 40 cents/hr (saw this on PBS Frontline), no pollution laws so a polluting factory is far cheaper to run than one in America where we do have environmental laws, etc. That is the reality of our world today. It's not a pretty picture for American employees of radio or industry, but the excessive greed of these corporations is one of the root causes for what's happening.
I wonder how long it will be before CC and CBS radio, etc, gets the idea that they could produce their programs from a studio in India and pay those on air folks 40 cents/hr as many telemarking, customer service centers have been relocated with India people answering the phone and saying in a heavily accented English, Hi ! This is Robert. I always want to say back to them, yea sure and my name is Harish. So who knows, maybe the next big thing in radio (both talk and music) will be the Indian version of Rush. I can hear it now, Hi this is Ramesh Patel Show, your conservative guiding light for US. We go to phones shortly, but let's listen to sound bytes first, etc, etc.
