The latest front in the war between The New York Times and The Wall Street Journal is the glossy luxury magazine. Both T Magazine and WSJ . Magazine will have new editors this fall, and both are veterans of big consumer magazines: T’s Sally Singer was a features and fashion news editor for Vogue, while WSJ.’s Deborah Needleman worked for Domino. Journal employees say Needleman’s hiring was not a response to The Times’ hiring of Singer, but the old editor of WSJ. announced her resignation just nine days after Singer’s hiring made news. From the outside it sure looks like a luxury mag arms race. The move follows a big challenge from The Journal to The Times’ metro New York coverage with ads clearly mocking the Gray Lady.
