Columbia University, which hands out the annual Alfred I. duPont Awards for Journalism Excellence each year, presented one award Wednesday night to NBC's Dateline and another award to a Texas TV station for a feature that condemned the NBC magazine show. Dateline received the award for an August 2006 feature titled "The Education of Ms Groves," about a neophyte Atlanta teacher's struggles with her first-grade class. Shortly thereafter, an award was presented to Dallas TV station WFAA, an ABC affiliate, for a feature titled "Television Justice," which condemned Dateline's "To Catch a Predator" series. TV Newser reported Thursday that several NBC executives, including NBC News President Steve Capus, walked out of the ceremony before the WFAA award was presented, then returned afterwards.
