Today's the day that a huge shift in the New York talk-radio wars begins, Newsday's Andy Edelstein reports. Rush Limbaugh, left, and Sean Hannity's long-running shows will be moving from WABC/770 to WOR/710. The shows will air in the same time slots as before: Limbaugh from noon to 3 p.m. and Hannity from 3 to 6 p.m. Meanwhile, Michael Savage, formerly a mainstay at WOR, will be moving to WABC, where his show will air in Hannity's old afternoon slot. No replacement for Limbaugh at WABC has been named yet.
