The WSJ this week launched CEO Brief, a newsletter designed to inform readers, and to attract new members to the WSJ Leadership Institute. This organization is already a Dow Jones profit center, and a great example of how Tier 1 can lessen dependence on advertising. Former Fortune CEO Alan Murray runs the institute and is the nominal editor of CEO Brief — and promises to read every bit of reader mail — though he has delegated the writing of the newsletter to subordinates in the early going.
