How long will it take Cumulus to ask "Why is WYRK unchallenged?"
Even with my limited knowledge of the market, I can't see Cumulus doing anything more taking a bite at 'YRK's heels. Try to knock them down in rank a couple notches to help their own stations.
Mounting a full-on challenge - even with the likes of Mike McVay on board - is going to be long and costly, I don't see Cumulus willing...if indeed they are able...to make the investment. Also I find it hard to imagine them hiring a live, local airstaff at any of their stations in market #53. Heck, one of my Cumulus friends in Dallas VT's weekends in Atlanta.
I know someone who was once PD of a CC Top 40 that toppled a Cumulus competitor, a heritage Top 40s with a long track record of success. Later, this co-worker was interviewing with Cumulus for the PD gig at that former giant...and when it became obvious that Cumulus had no interest in changing anything to try to regain their #1 ranking, the interview ended. If this is typical of how they operate, the only thing I see them doing in Buffalo is making life easier for Townsquare, Entercom, etc.
