With the addition of Atlanta, there will be an all news station in every Top ten market. However,KRLD and WBZ are all news from 5AM to 8PM. I 'm not sure if KRLD does all news on Saturday and Sunday.
I guess Miami, Minneapolis-St Paul, Phoenix and San Diego are the biggest markets without an all news station. I don't even think Minneapolis and San Diego do all news in morning drive.
Miami will never get an all-newser. Too many Spanish listeners to put on an English speaking all newser
