Prop 8 News Coverage

I noticed that in the Bay Area I saw numerous commercials in favor of "No on Prop 8" and a few for "Yes on Prop 8." However, a friend of mine from Orange County explained that in her hometown there wasn't broadcasting for "No on Prop 8" and a lot of broadcasting about "Yes on prop 8." This seems a little biased and makes me question the "objective" angle the media "takes".
