Today in Media Files, Australian Financial Review columnist Joe Aston and Harvey Norman boss Gerry Harvey are in a war of words, and newspaper ad spend was down by a third last month.

Good feud guide. The Australian Financial Review's Rear Window columnist Joe Aston has stepped up his latest feud with Harvey Norman boss Gerry Harvey. Aston picked a fight with Harvey in a column last week, reporting on the business' financial state. And Harvey responded with a particularly nasty, unchallenged attack on Sky on Wednesday night. Norman called for Aston to be "stripped and flogged". "He should be hung [sic] or he should be stripped and flogged, the bastard. The Fin Review is supposed to be this wonderful paper with quality journalists and instead of that they have this gossip writer telling lies. He should be sacked tomorrow. He's an absolute disgrace."
