The Jewish community in SoCal -- not even limiting that to Orthodox Jews near Pico -- is big by comparison to the SFBA or Puget Sound, but it's a fraction of New York City and suburbs. (In fact, Long Island alone dwarfs it.) And there is no radio station anywhere in the entire NYC market that specializes in Jewish programming, and there hasn't been since WEVD was sold off by the Forward Association 20-or-more years ago. There's a program here and there (Zev Brenner's Talkline comes to mind), but no dedicated stations. So why would you think that idea would work on KABC?KABC's transmitter is about four miles from Pico -Robertson, the largest Orthodox Jewish community west of New York. Would a format targeting this community work for KABC?
Like David says repeatedly, regarding the Hispanic/Latino populations in the USA, the Jewish "community" is made up of many communities, with different levels of religiosity (including "completely secular"), different cultural tastes, different musical/entertainment tastes, different political orientations, different sexual orientations, different, different, different. About the only thing that draws us together is support for Israel, and even there, where there are two Jews, there are three opinions. So again, why would you think that idea would work on KABC? Even assuming it was for sale, and there was a willing and foolish buyer to take it off Cumulus's hands?
