In this final edition of Speaker’s Box, David Stewart suggests that the advertising and marketing disciplines confront a crisis of accountability not seen since the television quiz-show scandals of the late 1950s. A perfect storm of concern among consumers, investors, business, and government has produced a growing call for heightened regulation of advertising and marketing practices. Stewart explores the sources of these concerns and calls for greater transparency, more proactive self-regulation, and greater dialog about industry-wide solutions. We thank him and our previous Speaker’s Box authors for their contributions to the series, which has aimed to bridge the gap between the time it takes to produce rigorous research and the acceleration of change within practice. I am joined in this sign-off by Nanette Burns, who has skillfully edited the series over the past five years. We look forward to new developments with the Journal.
