LeaderBrief is the MediaBrief interview series with the people who run marketing, communications and consumer businesses. Each piece gives one named leader room to explain a decision: how a brand was repositioned, how a media budget was rebuilt, how a discipline is changing. Headlines in the series carry the LeaderBrief label. It is one of the oldest things on the site, first published on 23 December 2015, the same day MediaBrief published its first Public Relations piece, and it now runs to more than three hundred and fifty conversations.
