I don't know what happened with the Dodgers and KFWB (which is also right-wing but never ran hate promos during games), but it's almost always the stations that don't renew broadcast contracts because carrying baseball just isn't profitable in most markets.
Play-by-play radio consultant Bob Snyder has one word to describe the current radio rights environment: horrible.
"For every profitable radio rights play-by-play deal, there are probably 10 that are not," said Snyder, who owns Beason Broadcast Partners outside Chicago. Across all sports leagues, the soaring rights fees paid to teams over the last decade have caught up to the radio stations, and many are now drawing the line. The stations' financial losses "used to be a justifiable expense," he said. Now, he said the losses have gotten so large that "it's no longer justifiable."http://www.boston.com/sports/baseball/redsox/articles/2006/04/13/red_sox_radio_deal_likely_to_top_12m/So, if it's such a crappy deal, why would KABC — which is owned by Citadel, a public corporation — sign with the Dodgers when they could make more money by filling that time with O'Hannity and other fascists?
One thing, though: Maybe they have a lot of sponsors who didn't buy time for spring, and the hate ads will be fewer when the regular season starts.
