>>>Rights fees are too expensive to be absorbed by one station. They won't be getting cheaper, and in this marketplace, it's unlikely that advertisers will pick up the expense.<<<
Like every other price in a free market, rights fees are determined by what a buyer is willing to pay, and what a seller is willing to accept.
If CBS is losing millions a year on baseball broadcasts in the New York market, it's hard to understand why they would want to pay more and lose more by bidding even higher, or why competitors would bid big so they could lose big money too. At some point there has to be an equilibrium price that makes some kind of sense for the broadcasters.
Some other professional sports teams buy their own radio time and sell their own spots, which guarantees a profit for the radio stations. And look at the problems the NY Islanders have had finding a good radio signal for game coverage, at different times in recent seasons they have been heard on a daytime AM, a low power local commercial FM, and an even lower power non-commercial college station.
At some point, the teams have to realize that while the prestige of being a particular team's radio affiliate may help promote the station brand, if the stations consistently wind up losing millions as a result that, kind of, defeats the station's reason for existing. You can't eat "prestige" or pay your bills with it either, and radio stations have bills to pay from electricity to employee salaries.
Splitting the "pain" of losing money on game coverage across multiple outlets in a market doesn't make sense. It's hard to imagine Bloomberg Radio 1130, or Salem's WNYM caring a bit about carrying sports if they can't be paid up front with a guaranteed profit on the coverage. Both stations provide backup sports coverage, and neither station relies on Arbitron ratings to sell advertising on its regular programs.
It will be interesting to see how much of a cume boost WEPN gets from being on FM when the numbers come out soon. If the FM numbers are large WFAN might have more incentive to go after the cume boost that being the Yankees affiliate could provide next year. However, looking at the WCBS numbers, it appears the Yankees provide a boost of only about 500,000 listeners to station cume, and that may not be near the size of the boost that being on FM could bring. Remember the top music stations have a weekly audience that is ten times that size. It's going to be an interesting few months for sports radio in New York.
