AOL Ad Chief stepping down after six months; revolving door continues

Lisa Brown, the latest head of ad sales for America Online, is leaving the company, according to a story reported in the WSJ. Brought in by AOL head Jon Miller, Brown joins a list of equally hard-driving successors– Bob Sherman, Bob Friedman, Bob Pittman–who were announced with great fanfare, then edged out as their miracle cures failed to revive the behemoths flagging ad revenues within a few months.
The WSJ story says that executive management is talking to TW ad guy Mike Kellyabout overseeing the unit. The Journal also reports that the well-respected Michael Barrettmay assume more of her responsibilities on a interim basis.
