A South Jersey media executive tells me an announcement could come as early as today re the sale of the Press of Atlantic City newspaper, which owner John F. Bitzer 3d's Pittsburgh-based Abarta Inc. listed for sale in January. Rupert Murdoch's organization, which owns the Wall Street Journal, the New York Post, and the Fox TV networks, and billionaire Warren Buffett's media group, which owns dailies in Buffalo, Omaha and other smallish cities, are among the rumored would-be buyers.
